[Q] e: can't mount /sdcard! ASUS Transformer EEE Pad

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After following the NVflash guide, my tablet is rooted with a flashed ROM, however I think it's a little outdated.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

[MOD] Data2SD (Enhanced) - I/O Fix

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

Thanks Gonna try this.
done the work install all three files in the OP, however it is taking a long time to boot....Can someone give me an idea as to how long this normally take onn first bootup after a fresh install?
please advise
tyfoxx

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!!!!!!

I don't know which kernel you installed, but with my kernel you don't need any modules at all - just mount and go.

Yes as _that says if you choose his kernel from the options then CIFS MOUNT works as it always does
Also you should upgrade to CROMi-X 5 found here

Hy and many thanks for your fast support.
I have tried with those 2 kernels:

and
TF700ata2SD Asus 10.6.1.14.8 Modded_that v4 Kernel.
In ether case cifs dont will work.
The errors are, no such a device or directory... this error I have fixed, I have createt a new account named asus, after that I become I/O Error.

I have tried with and without load via Insmod, but for load via insmod.
Even noiw I have changed the Account Name on PC from Asus Infinity to Asus, there comes now no I/O Error, but now permission denied...
First now I reboot PC and Tablet.
I´m confused....
With Account Name on PC Asus Infinity and no Password, I become I/O Erros.
I have deletet the Password, permission denied.
Change the Name to ASUS with Password, no such device or adress.
Without Password I/O Error...
Something is wrong in state denmark...

I have checked and disebled Firewall in my Fritz.Box and on my PC, nothing was blocked.
And yes, connected via the same Router over Wlan.
With ES File Explorer I have acces to the Directorys on my PC.
Now I have Installed Cromi V5 and it has Data2SD Kernels and Support.
Now first start runs and I will try it with new Rom...
New Rom is installed, but also here I have some Problems, not only with cifs...
Now cifs Error is again, no such file or directory...
...but I have found an other possibility to play my Files on Asus Pad.
Splashtop and Power Cinema V5 on PC. Works fine. I have full control over the tab to the pc desktop. Start Power Cinema, choose Music and the Sound comes from the Tablet only, I can also browse and start an play all my Files...
Is not the perfect way, but now I will try to connect the Pad via mini-HdMI-HDMI to my Yamaha Receiver.
Also I think that was not a clean installation.
I have flshed first mod_Data2SD.zip and bevor that I have wiped Cache and Dalvik.
Than I have flashed also with perform a full wipe the new Cromi V5 and the second Kernel I have choosen.
After the Reboot, all Apps, installed in the Crome V4.7 are still there...
Maybe I have some missunderstandings about Data2SD using.
I have to read and read again.
This is not my first Android an Flash... I have flashed some HTC, Samsung, unlocked, rootet ans so on, but the Asus confused me...
Hope for changes...

Well if you had data2sd on 4.7 and updated to 5.0 then you will still see the apps. I force it to use the correct partition regardless of the mount-data2sd file being flashed....

Yes, I also think so...
But where is a possibility to format the second ext4 Partition on SDCard???
There is no way in the first flash, modData2SD and nothing by flashing the CromiX.
I only can format SDCard, but this formats only the first Partition. I have a 16 GB Class 10 UHS 1 mSD Card, one Part is 10 GB second Part is ~4 GB. If I format the SD Card, only the 4 GB will be formated.
I think, this is the beginning of all my Problems here with cifs and so on.
I have seen, that the error "No such Device or Directory" doesnt mean the path to the PC, it means the path to the mountpoint. Under mnt/cifs is nothing Named like Music aand I cant create it there, its a read only file system...
So what can I do to become a really clean installation with nothing old in it?
Have I to flash first without Data2SD Support, than maybe instal a partition Manager for Android to format the ext4 Part on SD and than flash again but now with Data2SD???

I don't understand how your card is set up. Is the Ext4 partition 4GB? That isn't really big enough.
Also if you want wipe the 4GB ext4 then you must flash the mount-data2sd first in twrp.....

Yes, but the initial formatting must be done on a Linux system (or from the command line in Android with a proper mke2fs binary).

No no, missunderstanding...
10 GB is the ext4 Partition, 4 GB ist the rest from the total 16 GB IHS 1 Class 10 mSD Card.
And I did this as well, first flash the mount Data2SD.zip file, and I also wiped there, than I reboot, Power off and go again to twrp and flash the CromiX5 with Kernel how supports Data2SD an perform a full Wipe...
Allways there are still all apps on SDCard, I cant controll it, I dont have a Linux system here...
After the flashs I have only a updated Cromi, not a new system.
First boot runs and its like before.
Is there no way to format the 10 Gb ext4 Partition? Win7 x64 and Acronis could´nt read the ext4.
ooops, I did it again...
I have seen, that I can format the ext4 with paragon partitons manager suite 11 I have installed.
Is this a conform format for this job?

In my Tablet ist shows only 4 GB, the 10 GB I cant see.
Retest with Acronis Disc Director Suite 11 and it shows 4 GB Fat32 first part and 10 GB second Part as unformated.
A friend has done the partition and format Job for me, so how can I change this??
Can a take Paragon to create first Part ext4 10 GB and the rest 4 GB Fat32 for this job?

What a f....
Now the using of Data2SD is history.
From 7am to 1pm I have tried to format an correct the Partitionstype of my 16 GB Class 10 UHS 1 mSD Card but it was only wasting time.
I have tried these jobs with MiniTool Partitions Manager Home Edition and SD Formatter.
Here I found a german page with Infos to create a ext4 Partition:
http://www.handy-faq.de/forum/android_forum/219275-ext4_partition_erstellen.html
But the Card was useless in PC and Tablet.
Now I have a fresh Installation, without Data2SD, but all my Apps are gone and not recovered by Market Place.
So I have to flash again.
Have someone here a Link to an Howto to create ext4 10GB first Partition an the rest ~4 GB with Fat32?
I´m helpless and frustrated.
So please, give some help.

People in the Data2SD thread said that MiniTool doesn't work correctly and that you have to use a Linux-based partitioning and formatting utility, e.g. gparted.
And if you create your ext4 partition first, it won't be usable for Data2SD either. As the documentation of my Data2SD add-on says, the ext4 partition must be the second primary partition.
I'd suggest you attack one problem after the other - this thread was originally about some CIFS problems - are these fixed now?

No nothing is fixed an I have created this thread to fix the problems.
All goes hand in hand.
Without a clean installation of cromi nothing works, than all apps are still there with all the errors. If I cant instal properly correct than I have the same problems like bevor.
This all I have told ya, here in this thread.
Normaly the mount data2sd.zip has to format the ext4 partition while flashing and perform a wipe, but this was not happend. After flashing mount data2SD.zip, reboot and flashing than cromix5 with full wipe all former installed apps an accounts are still there, and so I have overtaken all old problems too.

Data2SD Tf700 - exact steps to do - please help!

Hi,
I used my TF700 for several month, and I am very dissatified. At the moment I use a cleanrom, without external SD. As I am allready rooted an unlocked, I am not able to send it back to my seller ...
So, my last chance to get the device a little bit faster, is to install cromi rom and use data2sd. But after reading hours in several forums, I am not sure, which steps I should do to install it and which files I actually need.
I bought a class 10 microsd card, partitioned into a fat32 and an ext4 partition.
So , whats next? (It never mind, if i loose my internal sd-card)
1. I have to flash an data2sd kernel, right ? Which one?
2. I have to wipe the sd-card?
3. Install the cromi-rom ... right? Which one? I downloaded CROMi-Xenogenesis ODEX 4.7.0_Signed.zip. Or is there a special Rom for Data2SD?
Are there any further steps?
Thanks for your help!

1) You should flash the lastest cromix rom here http://forum.xda-developers.com/showthread.php?t=2425383
2 Kernel, you have 2 choices:
a) Hund's custom kernel http://forum.xda-developers.com/showthread.php?t=2143093
b) _that modified stock kernel http://forum.xda-developers.com/showthread.php?t=2230059
3) I alway wipe everything if go from one version to the next, but from cromi v4 to cromv5 you don't have to, just verify that you have the latest bootloader mentioned here http://forum.xda-developers.com/showthread.php?t=2425383
4) Good luck!!

you have to do a bit more than that:
you need to make 2 partitions on your sd-card using Gparted Live CD as explained in the data2sd thread
http://forum.xda-developers.com/showthread.php?t=1962507
first partition: formatted as FAT32
second partition: formatted as EXT2 or EXT4 (i use EXT4)
both partitions need to be primary partition.
if you don't do this right, it won't work and the kernel will likely switch to internal memory (it happened to me
i always flash the twrp zip always first before i do anything else in recovery.
i have a 64gb class 10 card, my first partition is 8GB FAT32 so i can make backups to this partition and place the ROM files so they don't get lost after wiping, the remaining 56GB is formatted as EXT4 and used as internal storage.
I use the latest cromi, _that's kernel, data2sd, fsync disabled and cache2sd turned off.
It makes the TF700 a lot more usable, but (sorry to say) it's still not the machine it should have been....

first partition: formatted as FAT32 boot flag?
second partition: formatted as EXT2 or EXT4 (i use EXT4) boot flag?

The boot flag is irrelevant. Just make sure that both are primary partitions.

Curious, if one were to have made the mistake of having both partitions created as logical vs primary - what's the best way to resolve?
Fix and reboot?
Fix and re-flash and wipe cache?
Does this require a data wipe to work?
What's the best way to validate it's working correctly post boot?
Thanks!

In gparted you can convert logical to primary. Or wipe everything and start again.
As for knowing, you'll have a /datai folder where your old apps are stored as well as a new /data folder for new stuff. First boot will act like a clean install as well.

[Q] F2FS or Data2SD?

Both? Neither? One or the other?
Going to reload my TF700, probably with CROMBi-kk to try it out. Looking to optimize web browsing/facebook/gmail etc performance. Currently on CROMi-X 5.4.

Both = very fast

Very Fast would be good!! Format the internal memory as F2FS also, or just the sdcard?

If you use data2sd then internal /data is not used.
You only need to format mmcblk1p2 to f2fs on the card for data2sd.

faster than rom2sd? ive found it to be quick at times, then mighty slow at others. thanks!
if f2fs+data2sd is the faster option, how should i go about getting rid of the sd installation, just take it out and install like normal on the tablet?

I've noticed no difference between data2sd and rom2sd but f2fs allows better use of the tablet when things are downloading in the background for example.

thanks, is there a guide anywhere for moving from rom2sd to f2fs and data2sd?

Easiest way is install the latest TWRP 2.7.1.1 which has format options now for both ext4 (takes 90 mins) and f2fs (takes seconds).
You'll obviously lose everything if you format /data as f2fs so have a backup if you want to go back.
If you are using data2sd or rom2sd just remember to use the data2sd1.zip or rom2sd1.zip first to switch TWRP over to your external partitions otherwise you will be formatting internal.

So i boot into twrp, and format which partitions? the external sd card to extf4 and the internal to f2fs? sorry having trouble getting my head around this!

If you use data2sd (or rom2sd for that matter) you are not using the internal data partition for daily operations other than storage maybe. So you can leave it alone.
First step is to backup any data from the rom2sd data partition you want to keep.
Then you have to repartition the card. For data2sd you have to have 2 partitions (not 3 as in rom2sd): one fat32, one ext4 or f2fs. Do that in Gparted and while you're at it, you can format the future data partition to f2fs.
Then flash the rom with the data2sd option and _that v10 kernel.
I would also recommend getting TWRP 2.7.1

gparted?
so do i need to use gparted to partition my sd card or can it all be done with twrp and your crombi rom?

You must use gparted There is no other way.

Thank you. I'm doing my best to read through the last 100 pages of the q&a and the Rom page.

Go to the crombi-kk thread in the dev section and see post 2 - the instructions are there on how to do it
Once you partition it the installer will then do everything else for you

Thank you I did read that one, very straight forward. I am having trouble finding a zip containing twrp 2.7.1.1 ... I currently have 2.6.3-that3 but twrp manager keeps crashing on me and does not Let me choose a device in order to upgrade.

Download the blob from the TWRP site and install it via fastboot.

I got the file from techerrata with md5, is this a reliable source? Please forgive my newb green-ness
