Before you guys say anything, I've googled it and done everything there is to do. Here's a list:
1) Format and partition your SD Card in FAT32
i) Followed this guide http://forum.xda-developers.com/wiki/SD_card_partitioning
Didn't Work. I partitioned it with an ext 2. partition. No Success.
2) Followed this guide and NVflashed my tablet. I was able to restore it to factory settings, but it's still not mounting my sdcard.
http://www.tabletroms.com/forums/tr...ment/976-nvflash-unbricking-forever-root.html
3) Went into CWM, tried to format my sdcard, but it said ERROR! Sdcard not found (something along those lines)
4) Tried 3 other different SD Cards
The current version I'm running right now is: PRIME v1.4 (HMJ37.WW_epad-8.4.4.5-20110527
After following the NVflash guide, my tablet is rooted with a flashed ROM, however I think it's a little outdated. What should I do?
Thanks for reading guys!
Are you using a full size SD card or a microSD?
In my experience you have to use a microSD in CWM (and it is called SD)

Thanks for the reply! I've tried both. However, I tried them at the store. I didn't format them to FAT32 I just used them straight out of the package. Not sure if that would make a difference.
Also, my tablet version is currently PRIME! V1.4 and it can't update. I'm a little lost. The build number is 8.4.4.5 and I know there is a higher version. I followed the NVflash guide mentioned in my first post.
Prior to downgrading my tablet version was 8.6.5.21 and it wasn't mounting my SDcard, which is why I downgraded. Now some of the accessory keyboard functions don't work (ie Alt+Tab) and the weather check app isn't working.
Anyway to restore it to stock settings without root?
Edit: Found the answer to my own question. How to reset to stock? Can't post links here so google "Asus Transformer NVFlash Stock 3.1 & Stock 3.2 Recovery Roms" and look for the post by zerofeel. I downloaded the NFVlash of the 3.2 Build of 8.6.5.13 for US.
I would still like help with the microSD card error though! Please and thank you! I'll try formatting the microSD to FAT32
At the suggestion of several users, I am forking the previous thread. I am planning on supporting several ROMs and this is the best course to keep everything organized and provide support.
What is this?
Background:
The speed of the flash memory in the Transformer line of tablets is very poor. This is very apparent when installing or updating applications from the Play Store, copying files over USB, or using an app that caches lots of data like a web browser. The tablet will hiccup and stutter due to the I/O bottleneck. Running Androbench shows random write speeds averaging less than .2MB/sec.
The workaround:
Utilizing a fast, class 10 microSD card, we can move the /data partition to something significantly faster. The /data partition is where apps are installed to and where they store their configuration information and data. By redirecting /data to these fast microSD cards, we eliminate this bottleneck from our devices. With a properly fast card, users have reported a complete elimination of I/O related hiccups and system freezes. I have based my enhancements on the initial work by TweakerL on the Transformer Prime. Credit to fordwolden to porting his work to the Infinity.
The enhancements:
Previous implementations of this mod had the internal data partition mounted to /data2, with the media subfolder (your internal user storage) only available via root apps. There were symlinks set up at /sdcardi, etc, but these still required root permission to access. This is due to permissions on the /data partition and applies to both /data and /data2. Google gets around this by creating a "virtual" sdcard that points to /data/media. I have created a second "virtual" sdcard that points to /data2/media. This mod creates the scenario below:
/data = ext4 partition on microSD (fast)
/data2 = ext4 partition on internal storage (slow)
New changes:
/data/media -> Virtual SD Card Daemon -> /storage/sdcard0
/data2/media -> Virtual SD Card Daemon -> /storage/sdcardi
/sdcardi -> Symlink -> /storage/sdcardi
/mnt/sdcardi -> Symlink -> /storage/sdcardi
/storage/sdcardi is the virtual SD card for the internal storage. You should see all the files you had saved to this space before using data2sd. These files should be accessibly by any standard non-root Android app.
Note to kernel developers: This mod is more than just changes to the kernel. In order for the internal storage to be properly mounted at /storage/sdcardi, I have modded the Virtual SD Card Daemon that comes with Android. The stock binary is /system/bin/sdcard. I made a copy, modified it using a hex editor, called it /system/bin/sdcardi, and included it in my flashable zips. If you wish to make a data2sd version of your kernel, you must include this file in your zip. Additionally, be sure to add the "service sdcardi" line to your init.cardhu.rc that I have in mine.
Installation
Requirements
1) Class 10 microSD, at least 8gb
2) A computer with card reader
3) Partitioning software. Recommended: gparted LiveCD
Instructions
1) Decide how big you want to make the ext4 partition for /data. Remember, this is going to be the space for installing applications AND the /sdcard space that games will use the cache their extra data. Kindle books, Dropbox files, pics from the camera WILL ALL GO HERE. Personally, I decided to make the ext4 partition the whole 64gb of my card.
The ext4 partition has to be partition #2 on the microSD card. Why? This is to give people with large cards the option of creating a FAT32 or NTFS area as partition #1. This allows the card to be read by a Windows or Mac computer using a card reader. I use my tablet as my card reader with the USB cable, so I wasn't worried about this. I used gparted to create a small 8mb unformatted partition as partition #1, then a second 64gb partition to fill the rest of the card. I formatted this second partition in ext4.
2) Format your microSD card - Download Gparted Live CD (http://goo.gl/dJQAu) and use Imgburn (http://goo.gl/33MY9) to write to disc. Boot to Gparted using your CD after setting the CD as the primary boot device in your BIOS. Once in Gparted, create the 2 partitions described above, the first partition is Fat32, the second partition is ext4 or ext2. Set both partitions to type: Primary.
3) Insert microSD into tablet and flash any data2sd kernel for your ROM. (Note: Flashing any ROM will overwrite your data2sd kernel. You will have to re-flash the data2sd kernel if you change ROM or even upgrade your current one) After booting back into Android, you should be greeted with the Setup Wizard. Remember, this is a fresh /data partition, so it's a clean slate. It's a good idea to take a TitaniumBackup** ahead of time. I am experimenting with ways to make the transition more painless.
**Note about taking a TitaniumBackup before switching to data2sd. After the conversion, your internal storage will be mounted to /sdcardi. By default, TitaniumBackup looks for previous backups in /sdcard not in /sdcardi. You have two choices. Copy the TitaniumBackup folder from /sdcardi to /sdcard and restart the app, or change the backup location to /sdcardi/TitaniumBackup in the app preferences. Either of these options should work fine.
Optional: Verify data2sd is working. Pick any method you like:
a) Open a file explorer such as Root Explorer, ES, etc. You should see /sdcard and /sdcardi and be able to browse the files within. /sdcard is your ext4 partion on the microSD while /sdcardi is the internal storage. You should able to copy data between them.
b) Download "Androbench" app from the market and run "micro" sdcard check, if you see 0.4mb/sec or more in random write you're on data2sd.
c) Power off your device, remove your microSD card, then power back on your device. You should received an error message "Encryption unsuccessful". Insert microSD and reboot to fix.
Uninstallation
Don't like data2sd? Just flash a non-data2sd kernel using recovery and when you boot back into Android your /data will be on the internal storage. This could also be accomplished by flashing your ROM on top of itself without wiping.
Troubleshooting
1) Grab the mount-data2sd.zip from the second post.
2) Boot into TWRP and flash the mount-data2sd.zip. This will mount the microSD as /data in recovery. It will allow us to wipe it, format, etc using recovery.
3) Wipe "Internal Storage". This will erase the entire ext4 partition on your microSD.
4) Flash ROM
5) Flash data2sd kernel for ROM
*CAUTION*: If you don't flash mount-data2sd.zip before your wipe, you will be wiping your internal memory.
Download data2SD kernels
These are flashable zips. It will disable journaling on the microSD ext4 partition. You do not have to do this manually! Flash these after flashing the ROM.

Recovery
I made a flashable zip to help the recovery console understand our modification. By default, if you go into recovery and do a factory reset, it is formatting the /data partition on the internal storage. The issue same applies to nandroids. We may be using the second partition of our microSD card for /data, but the recovery does not know this. It will look to the internal /data partition during backup and restores.
This zip does not make any modifications to your tablet or copy any files. It simply updates your recovery mount points. The changes are temporary and are lost during the next reboot. You will need to flash it each time you boot into recovery.
After flashing this zip you will be able to:
1) Wipe data / Factory reset. The /data partition on the microSD will be wiped
2) Backup and restore nandroids. The /data partition on the microSD will be backed up or restored.
3) Choose "Flash zip from internal sdcard" and browse the files on the internal storage
4) Access and flash zips from the microSD storage. Choose "Flash zip from internal sdcard" and notice the !microSD folder at the top. This is a symlink that will kick you over to the microSD storage. This !microSD folder appears on your internal storage after you flash this zip for the first time. It remains unless you delete it. Even so, next time you enter recovery this !microSD symlink will not go anywhere until you flash this zip.
Please report your experience with this.

This one too.
So this is basically flashable on CleanRom 2.3 right? Only thing wrong is that it doesn't show up in windows over USB? I can live with that as long as apps can read it in the Android OS itself.
can I use flash this on cleanrom 2.3 to diasable journalling on my ext4 partition

Use recovery to wipe the /cache partition. Due to the changes in framework-res.apk this may be necessary if you aren't coming from a completely clean install of a ROM.
I just booted to recovery and wiped my microSD /data partition. I also wiped /cache and /system. I installed CleanROM 2.3 and in the same recovery session I flashed the clemsynTF700ver22GPU650VC-data2sd kernel and it booted right up.
May be a stupid question but do you still need TWO primary partitions on the SD card (i.e., first is FAT32 while second is Ext4 and used by the mod)? If this isn't necessary or not possible, should the recovery (i.e., installation) files be placed in internal storage?
Forgot to mention I'm using Windows 7 MTP and CleanROM 2.3

Couldyou make one for blackbean? i tried thecm 1029,but it doesnt boot. Would greatly appreciate it.
Sweet
I just ran every shortcut I could think of:
I used Mini partition tool to reduce reduce my 32 gig fat down to 16 gigs & then created a 16 gig ext4 partition.
Wiped everything in twrp and re flashed Clean 2.3 then the new zip.
All I can say is WOW.
Restored everything. Works great no more stalls and stable so far. Hope it stays this way. Now to focus on battery life.

Glad it's working! I've prepared a little treat for everyone to make our recovery lives a little easier. Need to test a few more things before I post!
I'm running CleanROM 2.3 and ClemsynTF700ver22GPU650VC (awesome combo, btw). If I want to use this MOD, should I need to flash first CleanROM-2.3-data2sd.zip and later ClemsynTF700ver22GPU650VC-data2sd.zip, right? Of course, also, formating my microSD using ext4.
Awesome work here Mistar!!!! Thank you so very much for this!!! Gonna replace my SanDisk 32gb Class 4 card with a SanDisk 64gb Class 10 before I run this on CleanRom. I'm super excited about this mod!!!!!! Thanks a million!!!!!!

*** The sdcard card created by this thread is not compatible with the original sdcard installation of CM10/CM10.1.
This is a work-in-progress and things are changing very fast so you may lose some of your data as we moved from one version to another.
After a brief discussion with leapinlar few weeks back, this is a new CM10.1 sdcard installation based on that discussion.
Features:
Dual boot stock and CM10.1.
Using only three partitions to allow stock to boot properly.
/data is stored in emmc while /system is in sdcard (Caveat: Doing stock factory reset inside stock will wipe out data of both the stock and CM10.1)
Can be flashed with ROM from this thread starting cm-10.1-20130130-UNOFFICIAL-hummingbird.
/data maximum size is now only limited by the size of the emmc.
For installation instructions follow this post. Thanks Diogenes5.
CWM Image file: sdcard-cwm-hummingbird-hybridv2.zip. Date Posted: 2/2
Data Wipe/Factory Reset now working.
Backup/Restore to/from both emmc and sdcard now also working. (/boot will not be backup and restored)
uImage.20130613.hybrid.hd.zip and update.20130613.ramdisk.hybrid.hd.zip *** latest ***
Fixed: Intermittent boot problem
cyanoboot now working for lg display.
update-20130221.zip
cyanoboot modified to pass serial number to kernel command line for android to properly report a valid number instead of unknown.
update-20130204v2.zip
Fixed device booting to stock recovery instead from the stock ROM.
update-20130204.zip
cyanoboot modified to allow CM10.1 (cm-10.1-20130203-hummingbirdv2 and above) rebooting directly to its menu.
Older downloads:
CWM Image file: sdcard-cwm-hummingbird-hybrid.zip.
Update: Download View attachment update-20130201.zip and extract uImage and ramdisk.stock to the boot partition of the SD card created from the above file. You can now delete kernel.stock as it is no longer being used.
Stock now booting normally.
Added Boot from SD alternate in cyanoboot menu.
Thanks to leapinlar for the suggestions above.
TODO: Wipe/Backup/Restore operations under CWM.
Only CM10.1 ROM dated 1/30/13 and above will work properly with this new SD card installation.
Currently this installation is compatible only with leapinlar Stock recovery tool provided in this thread.
This hack/trick is already superceded by the above post.
BEWARE: This hack/trick should be used only by HD owners who are very familiar with SD card installation of CM10/CM10.1. This may or may not work. Using this tools could brick your device, you have been warned!!!
Prerequisite: Working CM10/CM10.1 SD card installation from this thread.
Instructions
Download the attached hybrid.zip file.
Make a backup copy of /boot/uImage before copying all the files to the /boot partition of the SD card.
Insert SD card to the HD and let the device boot from it.
Hold the 'n' button of the device until the cyanoboot menu is shown.
Press the 'n' button multiple times until 'Initialize Hybrid' is highlighted.
Hold the 'n' button for at least 3 seconds to activate it.
Wait until the device rebooted (Depending on the speed of the SD card, you may have to wait for a long time).
Enjoy a faster and smoother CM10/CM10.1
Note: To uninstall, delete ramdisk.hybrid*, ramdisk.sync*, ramdisk.sys*, ramdisk.data* and u-boot.altboot from the SD card. Delete both cm_system.img and cm_data.img from the EMMC to recover the 2GB of storage space.
Technicals/Details
uImage - updated cyanoboot for hybrid booting.
Boot menu descriptions
Boot Hybrid - uses ramdisk.hybrid as the ramdisk.
Initialize Hybrid - uses ramdisk.sync as the ramdisk.
Sync System: SD -> EMMC - uses ramdisk.sys-sync as the ramdisk.
Sync Data: SD -> EMMC - uses ramdisk.data-sync-emmc as the ramdisk.
Sync Data: EMMC -> SD - uses ramdisk.data-sync-sd as the ramdisk.
Default Boot Image - uses u-boot.altboot as configuration file.
ramdisk.sync - will check whether cm_system.img and cm_data.img are present in /emmc. If not create the two files with sizes 800MB and 1200MB respectively. Loop mount both files and copy the contents of partition 2 and partition 3 of the SD card. Rename ramdisk.hybrid.copy to ramdisk.hybrid to enable the cyanoboot menu Boot Hybrid. Store the value 1 to the file u-boot.altboot to enable default booting from hybrid/EMMC.
ramdisk.hybrid.copy - will be renamed automatically by ramdisk.sync to ramdisk.hybrid to enable booting from cyanoboot menu and default booting when the value 1 is stored in u-boot.altboot
ramdisk.sys-sync.copy - should be manually renamed to ramdisk.sys-sync to enable cynoboot menu Sync System: SD -> EMMC. This is needed to update cm_system.img after a CM10/CM10.1 update of the SD card by CWM.
ramdisk.data-sync-emmc.copy and ramdisk.data-sync-sd.copy - should be manually renamed to ramdisk.data-sync-emmc and ramdisk.data-sync-sd to enable syncing data both ways. (Not included yet)
u-boot.altboot - created with a value of 1 by ramdisk.sync. Changing the value to 0 will default to normal SD boot. Value can be changed while in the cyanoboot menu.
Pros/Cons
Pros
Very fast and smooth interface.
SD card can be unmounted and removed.
Cons
SD card is always needed during boot time.
Update should be done to the SD card first before syncing with EMMC.
Consumed 2GB of spare EMMC storage.
Reboot to recovery sometimes is not working and will reboot to EMMC/Stock recovery.
Bokbokan, if you get this working so that you can get the SD down to 3 or less partitions, I have a trick to let it boot to stock with the card still in.

Is there a speed gain for those whose cards are already faster than nand, or that's mostly for those what have slow(er) cards?

I can try booting from the stock using customized kernel and a ramdisk sourced from the EMMC but so far haven't tested it because of my bricked stock. Did not bother to restore it yet since this make my device easier to boot/reboot from SD.
What trick do you have up your sleeve?

This is very useful for those having very slow/moderate card speed. For faster card the benefit is to allow the device continue running even without the card except during boot time.
Very cool! Will play with this shortly!

Actually there are two ways.
The first is to put the stock ramdisk in the SD boot partition. For me I don't run your CM10 so it was easy for me to make it boot to stock by putting it in the CWM SD card. Then I select SD and it boots to stock. But that does not help CM10 users because they need ramdisk to be for CM10.
But for CM10 users, you can install Quick Boot from the Play Store and install it in CM10. Then tell Quick Boot to boot to bootloader and it boots to stock. But with verygreen's/your CM10 SD partition structure, stock hangs at 99%. That is because stock chokes on 5 partitions on the SD. That is why I was saying that if you could get down to 3 partitions, you could boot to stock from CM10.
But on my HD+, which I do run CM10, I changed the partition structure so it only has 3. But I don't expect users to do that. It needs to be built into the SD from you and verygreen. That is why I like your idea of putting some things on emmc so the partitions can get down to 3.
But I will briefly explain what I did to customize my HD+ CM10 SD. I deleted partition 4 and 5, normally the sdcard partition and the extended partition that holds it. Then I moved partition 2 and 3 to the end of the SD. Then I expanded partition 1 to fill the space. So I have a large fat32 partition 1 and partitions 2 and 3 the same size as original at the end of the SD. Then I modified vold.fstab in /system/etc to point to partition 1 for sdcard instead of 5. And now the hard part. I modified the CWM SD so it also points to partition 1 for sdcard so it can find updates. I also removed the /boot entry so a nandroid would not backup my sdcard as part a backup. The /boot was not backing up/restoring properly anyway.
This is highly customized and I don't think users should do this, but it works.
The down side is your boot files are mixed in with your sdcard files and are vulnerable to tampering by the user. But the Nook Tablet SD installs do this, which is where I got the idea. And on the positive side, Windows can now see sdcard when plugged in directly and stock can use the card as an external SD with no modifications.
One of the challenges for you and verygreen would be how to dynamically build the SD with this structure for varying SD sizes. I had to do it all manually and I don't think you would want users to do have to do that.
So this is just some ideas for future configurations.
Edit: One idea is if you could put /system and /data both on emmc, and create sdcard as p2, then you could have the boot files and sdcard files separate. And it makes it easy to create the SD dynamically. But you do not get the advantage of Windows seeing the partition or stock seeing sdcard without modification.
I do have my HD customized that way. I have my CWM card modified for stock with a big fat32 p2 to use for stock external SD and then modify the stock vold.fstab through symlinking. And I put the stock ramdisk on the SD boot partition like I described earlier. That way I never have to take the SD out. Stock and CWM are available in the boot menu.

Wow! This is great!
[edit - some more thoughts]
Spent some more time playing with this - the performance is vastly, vastly improved over my sdcard. Virtually all lag is gone. The actual conversion process was an absolute snap, and everything is running perfectly. Really, really excellent work.
Now, to upgrade, I assume that I boot into recovery, install the system, then *on next boot* choose the sync to EMMC option? Is that what you suggest?

CyanoBoot is not useable
I have used leapinar's sdcards as well as yours for cm10 and cm10.1 but I have always had this problem where on boot, I can sort of see the screen for cyanoboot, but it is compressed and distorted at the top of tablet. I can not operate the cyanoboot menus at all and pushing n seems to do nothing.
I have copied the hybrid zip files to /boot but the tablet just skips through cyanoboot and boots cm10.1.
How do I get cyanoboot viewable and to function properly?

The way you describe the screen is normal with the flash of distorltion at the top. As soon as you see that flash press and hold the n key until the boot menu comes up. If it does not come up, you may have a defective n key.

I missed adding that in my original question. When the distortion pops up and I press n, the screen goes blank and then nothing ever happens, just a blank screen. I have tried this with 3 different sandisk 4gb class 4 cards and the behavior is the same. My n button seems to work fine under stock, CM, and in CWM; it only seems to be a problem when trying to access cyanoboot.
Do you still think it could be the n button, and if so would there be a way to use ADB to do the hybridization check?
If this is the button how do I get B&N to replace it? "well ya see it works fine until I try to hack your loader and install a third party ROM, can I have a new one?"

You say this happens with my CWM for stock version too? The latest version? Some users were having that problem on an earlier version of my CWM. Bokbokan said earlier that the HD comes with two different screens and my earlier version was failing on one kind of screen. I revised the image and it fixed the problem.

You say this happens with my CWM for stock version too? The latest version? Some users were having that problem on an earlier version of my CWM. Bokbokan said earlier that the HD comes with two different screens and my earlier version was failing on one kind of screen. I revised the image and it fixed the problem.

I tried again with different cards using the hummingbird-v3.img from bokokan's HD CM10/10.1 thread. I also used the 6025 for emmc stock rev2 4gb img from your root/gapps thread on a freshly formatted sdcard and I always get the distorted screen.
There is nothing actually being written to the nook correct? Cyanoboot is the u-boot.bin file on the sdcard? Since I have had this problem all along is there a bad file from an early attempt I am not aware of that is on the internal? When I remove any cards the nook boots normally although I used your OTA plus gapps on the stock.

As I said earlier, the jagged distortion at the top of the screen is normal for everyone. And nothing important is being written to internal memory. All files for booting are on the card. I am thinking you may have the second screen manufacturer that bokbokan has not been able to test. Can you run an experiment?
Boot to CM10 and open the terminal emulator app. Type su enter. The prompt should change to a # after you grant superuser access. Then type dmesg. This should be done right after booting so the data is fresh. The screen should scroll a lot of data across the screen. Scroll to the beginning of that data and look for a line that starts "kernel command line:". In that line there should be a statement that says "display.vendor=". Tell us what it says after the equal sign.
I know just enough about this to guess that line is what we want to look at. Bokbokan will have to tell us for sure.

That is the second device he could not test. That is probably the problem. When he catches up with these posts maybe he can do something. His and my device say display.vendor=AUO.

You beaten me on this. Thinking to post the same thing. :laugh:
I wanted to go the data2sd route and tried installing by formatting the 64mb class 10 microsd with minitool partition. After installing everything , the tablet stuck at "encryption error" only option was to reset. It did that everytime i started it. So i did a factory reset, format system and it threw a error saying cannot format sdcard android secure. So i then reinstalled cleanrom using the unters rom at the bottom selection and deleted cache then dalvick took sd card out and rebooted. Finally no encyption error.
Looked in es file explorer cleanrom installed to the /data, ilooked in sdcard/ and there is a file that data2sd installed called !microSD and i cannot delete it. I opened /sdcard in root explorer and the !microSD isnt there, i tried "show hidden files" in settings but it still wont show. I booted clockworkmodand chose installfrom internal sd and the !microSD shows. I click on it and it just opens another !microSD, i can keep clicking it and at the top if the screen it will look like this /!microSD/!microSd/!microSD/ and on and on. I want to delete it or format the internal sd but i am scared to format it, i have heard horror stories of bricking when choosing format emmc or format sdcard. I have tried format system to startfresh but it will format system,then data but it will say cannot format android secure skipping format. I dont mind wiping /sdcard since i backed up a few pics and movies.
I did format the 64gb with gparted. I want to try data2sd again but imicrosd file needs to be removed most likely. I tried to rename it too but es file explorer wont let me.

Nevermind, i decided to bite the bullet and install cleanrom 3.0.3 and followed directions for data2sd. It installed without encryption error and the imicrosd file was gone. But from what i have eread about data2sd it didnt install correctly because the file system should have showed sdcardi which it didnt. I tried downloading a torrent movie and the tablet became unuseable,freezing. Also moving files from the ext4 to fat32 were sloooow. I decided to flash a kernal from the t700t forum on the data2sd subject. That resulted in the encryption scenario. So i factory wiped in clockwork and installed the newest cleanrom 3.3 and the 3.2 chromidata2sd file then the mount2sd file and then the kernal pack and used the 10.4.20 tf300 kernal. Rebooted fine. The tablet is real fast but i havent tried a torrent download. I also had two weird half reboots with each one when i tried deleting a file in file manager and then in es file. I do have a folder called internal sdcard which has the usual files on it. Didnt have that with the old 3.03. I did but it was empty.
Anyone know why it reboots when deleting a file? I did disable fsync though.
Don't use minitool to partition the card. It corrupts and causes reboots, etc. Even though the d2sd thread recommended it, don't.
Use gparted instead and all will be well.

I figured that out after the first encryption Error. I then spent all for one day trying to figure out how to partition the card in gparted. I should have deleted both partitions and then format them, instead I moved them in gparted and that took 4 hours. Then i found a write up on exactly what to do.

Well i just went through 4 hours of being terrified that I bricked my tablet. I kept getting reboots, i installed androbench and when i clicked on the benchmark button the tablet rebooted. Tried to run the benchmark again and rebooted again. I then tried to uninstall it which rebooted the tablet again. I went to clockwork recovery and wiped /factory reset i then proceded to reinstall cleanrom 3.3 with stock kernal,then format cache, installed chromi.3.2data2sd,wiped cache,started the kernal installer and chose unters 10.4.4.20 ,wiped cache,flashed mountdata2sd.zip, factory reset. I restarted to a bootloop. I then wiped and factoryreset again and installed cleanrom again this time choosing no kernal and wentthrough the steps and had a bootloop again. I started worrying and did another factory reset but installed stock kernal and didnt install data2sd, rebooted to a the asus screen with blue loading bar, that screenflashed black and then stuck on asus screen.
I then freaked outa bit because i dont save backups. I then did a horrible thing, i formatted emmc. I had read a few posts about installing a fresh rom for thepurpous of selling. A few posts mentioned that it was safe to format emmc but to be careful since it might format an external card too. I rremoved the sd card beforehand. I then did a factory reset in clockwork and proceded to install cleanrom . Install went fine and i clicked on reboot system. BOOTLOOP! I was really freaking out now. So i looked up format emmc some more and the horror stories started appear. I downloaded peri one click root+recovery/fix-bootloops+softbricks. I had android phones listed in system properties but no adb. While searching for a work around i came across how to reinstall stock firmware over a rom. I downloaded the tf300t firmwware 2013.01.18 up date unzipped it and threw it ona microsd. In clockworkmod i chose install zip from sdcard and boom fixed!!!!!!!!!! I was sooooo happy. So i now have a locked tf300t unrooted factory fresh. But there is one problem, in file manager on /sdcard/ there is that file that mountdata2sd.zip installed called !microSD that shows 0.0bytes and i cannot delete it. It doesnt show up in windows 7 though. I have show hidden files checked too. My plan is to reinstall clockworkmod and try data2sd one more time but i want to delete that !microsd file first. I need to make a few more posts until i can ask in developer forum.

i am same problem
I am new with data2sd.
I read from another discussion that in order to use data2sd on my TF700 tablet I have to create two partitions on my external SDcard (partition1 = FAT32, while the secod partition is ESXT4). I am using Samsung SDXC 64GB class 10 card. For some reason I could not format the EXT4 successfully. I have tried MiniTool partition and GPart USB and Disk boot.
With latest GPart I receive error "Input/Output errro during write on /dev/mmcblk0" with header message "Libpart Bug Found!".
I tried to leave the first partition empty then format the 2nd partition EST4 as well but it made no different.
Finally I ask a frined to format the card from his Apple laptop and he said he did it. However I am still unable to detect the 2nd paritition.
This time the Gpart softare has shown a Warning message as shown in the attachment.
Can anyone help me? Thanks

I have heard that MiniTool has corrupted a few users SD when they use it. If it is still new, you can get the exchange from where you bought it.
Otherwise, you could try this to see if it works out for you.
You can use a card reader and plug it in your window pc. You need to reformat your SD with extfat. If everything works, then you can use gparted to format two partions, fat32/ext4, to use for data2sd.
If it is still not working, you can go to the SD card associate website and download the format4.0 tool. You need to install the software on your pc and use it to format your SD. In the pull down option, you need to select the "overwrite" option in the menu and hope that they can repartition your allocation table in order for your SD to work again. Good luck... :fingers-crossed:
Finally made EXT4 partition successfully but still fail on DATA2SD
I finally able to format my second partition with EXT4 using TWRP software. However my TF700 tablet is unable to mount the EXT4 or read it under storage menu. I read another forum saying the SDXC UHS-1 card cannot be used for my tablet. Is this true?
Can anyone confirm this? Thank you

Note: When flashing using that4 DATA2Sd kernel, the screen hung at Asus logo. Tried using Hunsbuah kernel too but no luck. I am using CROMI-X 4.7.0.
Is it a micro SD you are trying to use? The full sized SD in the dock won't work for data2sd.
You must use gparted to format the card. There is no other way.
Take the microSD out and check if it boots normally. You may have corrupted your card with Mini Tool...

I am currently using an exactly the same SD as your. It is working for me. Something may be wrong your end..
Got the partition working and NOW is the mounting problem...
Finally i got my second partition working. The formatting worked after I recreated the partition table using gPART.
Now my ASUS TF700 could not mount the second partition of my Samsung card. It only read th first primary partition. After flashing ROM with CROMI-X 5.0 and select that_4 kernal (DATA2SD), it loop at initial Asus boot logo and then reboot repeatly and endlessly. Is there any step I am missing here? Thanks for any help here.

am using MicroSDXC UHS-1 card 64GB
Hi,
I am using Samsung 64GB microSDXC UHS-1 card and I inserted it into the tablet directly. The tablet could read first FAT32 partition but not the second one (EXT4). I could see the second partition using Mini Partition Tool as well as GPART though.
I am thinking hard now on how to let my TF700 read the EXT4 second partition on my card. ANy idea? Thank you

I try
1. I bought a SanDisk Extreme with 32 GB
2. I have used gparted to partion my SD Card. First with 4 GB Fat32. Second with Ext4. Both are primary.
3. I flashed the new TRWP 2.6.1.0 on my Tab.
4. Reboot the recovery an flash mount-data2sd.zip
5. flashed the Cromi 5.0.1 odex and use _thats data2sd Kernel
6. I flashed data2sd-jb42-intmedia-that1.zip
My Tab runs with this but i can't use the Ext4 form my SD-Card.
Pics go to the internal storage.

That's what "intmedia" does.
The ext4 partition should contain your apps and app data.

You have to use the mount-data2sd.zip from the data2sd thread to temporarily switch your recovery to use /data on the microSD card.

Hi, do you mind giving me tips on how to solve my problem? I am thinking if my tablet could not read the 2nd partititon on extenral MicroSD card, I will not get DATA2SD works no matter how. Please correct me if I am wrong. I have also installed mount-data2sd.zip from TWRP 2.6 and then flash Cromi 5.0 ROM using built-in DATA2SD kernel by that_4. the outcome is still negative.

May I ask how do you try to read your ext4 SD? Did you flash _that's data2sd zip file? I don't recall that I have ever gotten any problems with the exactly SD that you have...
Edit: If you use _that data2sd kernel, then you don't need to flash _that's data2sd zip file.. However, it is not a bad idea to flash it again to see how your tablet responses..

Hi, the way I checked is when I goto storage option, i could only see the internal and first partition on my external SDcard so I assume the 2nd partition is not recognized? Also using ES Explorer, I clicked "MicroSD" option and it only showed the content in the first SDcard partition.
These are the steps I did:
1- From TWRP 2.6.0, I flash a separate mount-data2sd.zip
2 - still in TWRP, once the above flashing complete, I flash CROMI-X 5.0 deodex and select that_4 data2sd kernel
3 - wipe cache and dalvik cache
4 - reboot system
5 - I got message there is no OS in the internal parition/disk do you want to continue? Since I got no choice, I clicked yes then the screen hang at initial Asus logo screen.
Luckily I have TWRP backup prior so I managed to restore my complete /data, /system and /boot or recovery.
Plz help and advice my misunderstanding or missing steps here. Thanks

First, can you tell me what rom and kernel you are running? I don't think that you can see your ext4 on your external sd unless you are using data2sd.. For now, you can use gparted to see if there is a second partition with ext4.. I need to understand your system a little more in order to help you set up data2sd..
