Data2SD MOD: Moves /data partition to External SD, noticeable performance increase
All files attached are flashable .zips Installation instructions updated.
clemsyns cpu OC 1800 kernel is out! Good stuff!
Symlink added to /data2 (internal storage now found as /sdcardi)
You will need to disable journaling using the guide in post #3 if you are on CleanROM 2.1 to 2.3
as the rom does this as standard. If not you will get error!
I have had nothing to do with the development of this MOD, all credit goes to TweakerL
Also a huge thanks to scrosler for the fantastic CleanROM
Thanks to clemsyn for the amazing kernel!
Feel free to go to original thread and give your thanks: http://forum.xda-developers.com/showthread.php?t=1803252
and also to seek information, the thread is full of it.
What/Why/How?
This MOD was developed to aid the I/O-issues the Transformer Prime has and the Infinity inherited. Since it was a known fact that the internal
storage was slow/poor, TweakerL decided to try mounting the /data partition to the MicroSD card. Hence an obvious necessity
will be that you have a fast MicroSD card. Several have been tried and there is no real conclution as to what is the best in regards
to manufacturer or class (a class 6 card can have better random write speeds than a class 10 card), I use a Sandisk 64GB UHS-I
class 10 card and so does several others with good results.
The way this works is that you change the ramdisk so that it mounts /data to the second partition of your micro sd. Your internal
storage (the old /data partition) will be mounted as /data2.
Requirements
1. Unlocked and Rooted
2. You MUST repartition your Micro SD. The .zip you flash will mount /data to mmcblk1p2, which basically says "mount /data to the
second partition in the external SD." also, the ramdisk expects that partition to be ext4, so essentially:
Make sure you have an external SD with at least two partitions and that the second partition is formatted to ext4. I use fat32 on the first partition
because it's recognized by most devices.You will also need to make both partitions "primary" partitions. I personally use Gparted to repartition
my stuff, but feel free to use whatever you like. Even if you're on windows you can still use gparted by using virtualbox, or you can use a tool
called MiniTool Partition Wizard, I haven't tried it myself but it is reported to be good.
3. Research your Micro SD, find out if it has good random write speeds. There is no use in this mod if you card is slower than your internal
memory.
4. Although it's not a requirement it is a recommendation to have gone through the Nvflash procedure. It has saved alot of people from bricks
and is just great to have.
5. Verify that the .zip is compatible with your ROM, if it is not listed feel free to ask for a version for your preferred ROM.
Disclaimer
I take no responsibility for whatever happens to your device using this MOD, it is flashing a kernel so take precautions!
Installation
1. Boot to recovery, flash your preferred ROM
2. Reboot to initial setup (Don't run through)
3. Reboot to recovery, flash the matching Data2SD.zip
4. Disable journaling (Optional on all ROMs except CleanROM)
5. Reboot
When it reboots you will get a blue progress bar and it will be just as you flashed a new rom, you'll get the device setup screen.With my
MicroSD I get about twice the Random Write speed with this mod; Internal=0.20mb/s External=0.40mb/s . We will have a look at doubling
these figures further down (I currently have Random write speed average of 0.8mb/s).
Reverting
Flash a ROM

Modded Recovery
Enough with the screenshots, I think people know what it's all about by now!
TWRP 2.3.1.0 Data2SD Edition
Modded by flumpster, thanks a million!
Attached is a version of the latest TWRP recovery, the only mod done is changing where
it mounts /data so it backs up the correct partitions!
Backup to External will backup to your first partition (fat32 maybe) and backup to internal will
backup to your ext4/2 partition.It is recommended to back up to external which is the fat partition.
If you backup to internal which is now the ext partition and something goes wrong with that partition
you wont have access to your backup.
Instructions:
You must remove the old twrp settings from your prime for this to work correctly. Delete any
TWRP folders that are in sdcard, data2/media and removable/sdcard. If you have backups there
already that you want to keep leave the backups folder in the TWRP directories and then just
delete the files that are in the root of the TWRP folder to get rid of the settings left behind.
If you are on a windows pc just extract the zip somewhere and run the bat file and then follow the
onscreen instructions. It will flash it for you. If not, navigatate to the fastboot folder, find the .blob
and flash the usual way with fastboot.
I have tested it myself but would love some feedback on this as I am currently the only one testing.

Disabling journaling!
This is a mod that flumpster tested and found to work fine. I have tested it to and it is fast as a shark. It is somewhat
controvertial though, someone thinks disabling journaling on the ext4 file system could cause crashes. Also if you are
plagued with random reboots it can cause data loss. I've been running it for a couple of days without issues and getting fantastic results.
Here is a description on how to do it if you want to try:
To Disable Journaling in EXT4
Go into TWRP and then open a command prompt on your computer where adb is.
Type adb shell and enter it then type the following commands one at a time.
umount /data
umount /sdcard
e2fsck -f /dev/block/mmcblk1p2
tune2fs -O ^has_journal -c 1 -i 1d -m 0 /dev/block/mmcblk1p2
e2fsck -f /dev/block/mmcblk1p2
Watch out for the fourth line, after tune2fs - that is a capital O not a zero. The one further along the line is a zero.
To check if it has worked type the follwing after them
tune2fs -l /dev/block/mmcblk1p2 | grep features
If you don't see has_journal in the output all is good.

And the size of the ext4 partition should be?

I was planning on taking a stab at porting this project to the TF700 this weekend. Thanks for your work! Going to test ASAP.

That is up to you really, the ext4 partition will be your new "internal storage" so if you if you need to store alot there like big games etc. you'll need more. If like me you have little use for internal storage you increase the size of first partition. I have 49gb fat 32 as my first partition and 11gb ext4 as my second.
I transfer movies etc. from a windows machine to the fat32 partition.
Good question though, I should have mentioned it in the OP.

Actually the ROM does this during install. However on 2.0 it was causing issues with the latest TWRP so I temporarliy took it out.
It ended up being a twrp issue. IM going to put it back in for version 2.1 (with will be 10.4.4.18 based) and revert to the old version of twrp. The newer 2.3.x builds dont seem as reliable at this time.
But good write up!

Also worth to mention that this mod makes it a little bit harder to do nandroids. But in TWRP you have a option to backup sd-ext, that will actually be a backup of your data partition. So to restore data you just restore sd-ext. All other partitions will backup and restore normally.
Edit: No longer applicable, sd-ext backup no longer supported. Modded TWRP recovery in post #2

Some feel more comfortable doing it! I feel like it's "bringing a knife to a gunfight"! False safety.

Since the 12/10 update to .18 that I installed just yesterday my performance skyrocketed. I don't experience any lag anymore, no hickups, much faster loading etc. I suddenly don't feel like this tablet was a waste of money anymore
It's all stock and normal.
So if you don't have this update yet, try it out before trying anything like this.

Would there be any way of getting this working on a rooted stock FW?
I saved root before updating to JB so I'm going to stay unlocked for as long as I have warranty.

Gospel singers from the General section? Now that's a first for me! I'm glad you're happy with your tablets,
now try downloading CleanROM 2.1 while multi-tasking on your device, still happy? I bet you want to unlock
before the download is finished!
New version for CleanROM 2.1 coming up, sorry for the delay. Been getting some sleep and my Inet connection
is about as stable as Uranium!
New version has symlinked /data2 partition so your internal storage will now be found in /sdcardi. Just for ease
of use.

[Q] Does updating your rom require you to re-apply Data2SD zip?

When a new update comes out for CROMI and you install the update, does that update require that you re-apply Data2SD or is Data2SD still on there?

I assume you will need to flash the mount2sd file so that recovery knows where to use? And then after the rom flash you will need to redo the data2sd patch so that the framework and kernel understands.

They way I interpret the question is your second one, sbdags: yes, you need to apply the CROMI patch new -- it overwrites files that the update (re?)installed that would make your 700 boot into the internal storage data store instead.

The -that3 kernel auto-detects a microSD card with a second partition and will boot into the Data2SD environment if such a card is inserted, and boot normally with the internal storage without card or with a single-partition card. The other mods to access the internal storage as sdcardi etc. must be re-applied in the ROM.

Funny thing is I only recalled that auto-detect feature in v3 of your awesome kernel earlier today -- I've been using v2 since it came out. </stupid> LOL!
I'm going to reflash later this evening and use your v3, just for convenience's sake.
@OP: _that clarified justly that if you use his v3 kernel you will not have to decide which version to get. The CROMI mod for data2sd should be reflashed after updating CROMI (and I'd advise you to flash _that's v3 afterwards!); I'm not really sure as to whether you need to flash mount2sd BEFORE flashing the CROMI update -- but it won't hurt!

I figured as much since if you're installing an updated rom or patch, you will need to install the data2sd zip.
Thanks for the info.

[Q] Help on SDCARD partition for data2sd

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

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, 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..

[Q] Cromi-X and data2sd

Hi, I could use some pointers on how to get data2sd on to my tablet.
I recently flashed to my first ROM, Cromi-X 5.0.3, and it seems to work well. Now I would like to apply data2sd in addition - maybe it was stupid, I guess it would have been smoother to apply that in the same move.
Anyways, I have set up a high speed micro-SD card now, formatted according to the instructions.
Now - I am a bit confused about flashing with a kernel - can I pick a kernel from the downloaded Cromi-X 5.0.3 zip-file, and flash that without any major wiping? If not, which kernel should I pick then... ?
Thanks!

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.
