Possible, card corrupted, please use gparted to reformat the card, then put the card backin and boot up again.

EDIT; I just check with the data2sd and I don't think sdbags is using the correct kernel for the tf300. sdbags needs to complile the new data2sd with tf300 kernel for your tf300.
[Asus Transformer TF700] Monkeydias:
On page two of his post, he has a link to the data2sd mod patch and a kernel to flash. http://xdaforums.com/showthread.php?t=2049322 Are those not ok to use?
[Asus Transformer TF700] buhohitr:
Nope, the new data2sd version is for tf700 only, I don't think any new data2sd would work, only the old version http://d-h.st/LTd may work, it's for cromi 3.03.
[Asus Transformer TF700] Monkeydias:
That's Odd. I got it to work once. Then I wanted to flash unters kernel on top of it so I used the kernel install from sdbags. Once I flashed unters kernel it took me back to being on the internal SD card.
[Asus Transformer TF700] buhohitr:
I think it's an easy fix by sdbags, he just need to take one of the .25 verion and convert it to data2sd for the tf300.
[Asus Transformer TF700] Monkeydias:
Hopefully he can do it. Maybe some dough for some beer would motivate him.
[Asus Transformer TF700] Monkeydias:
I assume I cannot use the old version of data2sd with cromi 3.3 correct?
[Asus Transformer TF700] buhohitr:
I would think you could, since I could use the old version for tf700. It's not going to be the best since the newest .25 kernel improved a lot over the old version.

Just wanted to say, everything seems so much smoother so far. Thank you, thank you, thank you...now I don't have to hate my infinity LOL

Give hundsbuah's kernel a try, it's even faster with data2sd. Recommend version 1.5 at this time.

[Asus Transformer TF700] Monkeydias:
Thanks for your help. I think for now, i'm just going to have to stick to not using the internal memory. Any idea why my tablet would no longer allow me to copy anything to the external sd card? I formatted the card back to fat32 using gparted and It will recognize the card, but says there is nothing on it and won't let me copy to it.
[Asus Transformer TF700] buhohitr:
Using root explorer or ES file explorerdo you see both /sdcard and /sdcardi or just /sdcard ?
[Asus Transformer TF700] Monkeydias:
I can see the card with the stock file manager and es file explorer, but neither will allow me to use it.
[Asus Transformer TF700] buhohitr:
No, my question is do you see both /sdcard and /sdcardi??? or just /sdcard?
[Asus Transformer TF700] Monkeydias:
I see both.
[Asus Transformer TF700] buhohitr:
That mean you're still limping on data2sd, you need to go back to the normal mode, you should only see /sdcard and you shouldn't see /sdcardi.
[Asus Transformer TF700] Monkeydias:
How do I get it out of data2sd mode? I guess restoring my backup before I did data2sd doesn't work because that's what I've been doing.
[Asus Transformer TF700] buhohitr:
Try to reflash one of the none data2sd kernel (use the kernel zip version 2.0) and see if you can access the /sdcard directory
[Asus Transformer TF700] Monkeydias:
Thanks for all your help today. I went ahead and reformatted the card and re-installed cromi 3.3 and now I can access the card and see the test files I copied to it after I formatted it. Now I get to set everything up again.
[Asus Transformer TF700] lmorel12:
HOLY SH*T!!!! Just got it done. I was struggling with the idea of going through all those pages. So yeah, I skipped, got lazy but came across smalis tips. Got the whole thing done under an hour. Ubuntu on a stick, booted it to Live version 12.10 on my Windows laptop. Inserted my Sandisk 64GB Class 10 card, fired up GParted and followed the basic instructions (do not forget to set your flags to make the ext4 partition to be active). All of that was super fast to handle (I'm not a linux person whatsoever but an IT person for over 15 years). My brain thinks and work with detailed instructions so having people to write good technical writing is not always easy to get. That includes myself. I think newbies like me on XDA get frustrated because they expect everything to be spelled out, just like in a manual. So I guess after taking XDA 101 for a few months, I started to enjoy myself around here. :)

Anyways, once I came across smalis' tips, things worked out SO well. No offense to anyone else, I just got lucky and it worked out for me on first try.

So what do I have to say about the performance? HOLY SH*T!!!! Awesome!!!!!!!!!!!!!!!!!!!!!! I regretted not getting the Nexus 10. Not anymore. Me happy. Thank you guys!!!!!!!!!!!!!!

EDITED: And thank you buhohitr!!!

What speeds do you observe with Sandisk?
[Asus Transformer TF700] bradslinux:
Seq read: 25 MB/sec

Seq write: 16 MB/sec

Ran read: 8: MB/sec

Ran write: .8 MB/sec

those are avg values. Sometimes higher, but usually not much lower. The big improvement is noticeable in actual usage.

[Asus Transformer TF700] buhohitr:
Mista, just want to let you know that your method of disable journaling is working perfectly and data2sd with Clemsy V7 kernel + fsync disabled allowed me to achieve the Quadrant record breaking of 7327..without any issue. Thanks for your work bro.
[Asus Transformer TF700] 7786:
How did you disable fsync if you don't mind me asking?

EDIT: nevermind, I saw it in the kernel thread, thanks!
[Asus Transformer TF700] buhohitr:
First you have to be on the latest Clemsy kernel V7, then do this for temporary disabling fsync:

Open terminal on your device, type

su hit enter, then type

echo 0 > /sys/devices/virtual/misc/fsynccontrol/fsync_enabled then hit enter, now fsync is disabled but will re enable after a reboot.

To permanent disable fsync do the following:

Use Root explorer or Es file explore navigate to this directory:

/etc/init.d

There is a file in this directory called 99CleanTWEAKS, tab on "Mount R/W" button on the top to grant r/w access to the file. Now type in the following line at the end of the file:

echo 0 > /sys/devices/virtual/misc/fsynccontrol/fsync_enabled

Save the file, then reopen again make sure your new line is still in there, also make sure the init.d directory and the file called 99CleanTWEAKS, both must have FULL read and write -rwxrwxrwx . Close the app then reboot. That's it

For those wondering which microsd card to use with this mod, I use a class 4 sandisk and have seen a dramatic speed increase. Random speeds are much more important that sequential. http://xdaforums.com/showthread.php?t=1150369 discusses the pros and cons of many cards. Here is a sandisk classs 4 vs class10 comparison.
[Asus Transformer TF700] NaxIonz:
I'm confused about the installation of this mod.

Can I do it on a vanilla device?

Or...

Does it need to be unlocked? Does it need to be rooted? Do I have to flash something like CleanROM to use this?
[Asus Transformer TF700] jodvova:
As you can see in the first post, data2sd mode is only available for CleanROM or CM rom.

In order to flash data2sd you need to have recovery installed (TWRP), so your device needs to be unlocked.

rooted = unlocked.

The steps to install:

1. install/flash CleanROM

2. format MicroSD card to have two partitions: Primary 1st, Primary 2nd - ext4.

Primary 2nd - is where /data will be mounted.

Primary 1nd - is totally up-to you what you will have there. Most of the people format it as fat32 so they can copy files on it in a card-reader.

Some people just leave it as small as possible to allocate the bulk of space for Primary 2nd.

It's very important to format MicroSD card under gparted (linux), in order to avoid potential problems with so-called bootloop.

After you've done that, plug the MicroSD card in and go to step 3.

3. without reboots install/flash data2sd

enjoy!
[Asus Transformer TF700] jaxboater:
FYI Wiping & a question

Found out that files & setting are not wiped on your micro sd.

I was trying to wipe everything with TWRP so that I could do a fresh install.

I flashed CR 2.3 & let it start up. I stopped set up at the 1st start screen.

(Same screen as seen when flashed the very 1st time)

I went back in Recovery (TWRP) and flashed CleanROM 2.3-data2sd.zip.

I did not flash clemsynTF700ver22GPU650VC-data2sd.zip while still in TWRP.

When I rebooted all my old settings came back.

I then flashed clemsynTF700ver22GPU650VC-data2sd.zip.

What's the best / easiest / fasted way to clean up / wipe the ext4 partition?

I wonder if the old files may not be causing problems for some.

I started out using MiniTool Partition Wizard, but noticed that the ext4 still had data even after deleting and creating again.
[Asus Transformer TF700] NaxIonz:
So, merging my other post, to make sure I do this very-first-time install correct:

Which CleanROM do I download to flash? I assume the one in the main CleanROM thread?

So, I do alllll that stuff you told me in the other thread, then:

- Format MicroSD card to have two partitions: Primary 1st, Primary 2nd - ext4.

- Without reboots install/flash data2sd

Few questions about those two steps.

For one, I don't have access to Linux. All I have is a Windows7 machine and a Macbook.

Second, when you use the verb "flash" for the Data2SD, how would I do that without reboots? Don't I need to go back into Goo Manager to "flash"?
[Asus Transformer TF700] buhohitr:
First just for you to understand. When you format your sdcard, the first partition, let call this P1 and you format P1 with FAT32, then you created a second partion called P2 and you format this with ext4. When you booted into TWRP, it only see your P1 and the Internal memory data partition. So when you wipe you only can wipe P1 or internal memory. Once you boot up it read read from your P2 so that's why you still see your old stuff. In order to wipe P2, you need to flash this zip: mount-data2sd.zip located here: http://d-h.st/pPe, after you flash this, power off your device and boot back into TWRP then do factory reset or wipe internal, now your P2 will be wiped. Reboot the device you will see factory screen with no apps from your P2 partition.

[Asus Transformer TF700] sbdags:
Well it includes a TF700 data2sd kernel but you can substitute that with unters data2sd if you want.

If you follow the instructions in post 2 of the TF300 CROMI thread but use the 3.4.xdata2sd file instead of the 3.0.3 one it is a tried method for the TF300.
[Asus Transformer TF700] buhohitr:
There are few issues with this, internal storage is pointing to dock sdcard (should be pointing to ext4 on microsdcard) and usbdrive1 is not working.

The correct way:

Internal storage-> ext4 microsdcard

micro sdcard-> fat32 partition1 of microsdcard

SD -> dock sdcard.

Data2sd working ok for me on 3.4.1 thanks :good:
[Asus Transformer TF700] Monkeydias:
I don't know what my 300's problem is. I have my card formatted via gparted in the following order. First partition, 2 gigs fat32, second, 27 gigs ext4. Both are set as primary. When the card is in my computer I can see it and copy files to it. I copied the mount2sd and cromi 3.4 data2sd files to it. When I insert the card into the tablet in 3.4, it mounts and I can see all of the files. When I boot into recovery, it says that it cannot mount the external SD. I thought the problem was clockwork mod, so I went ahead and flashed TWRP. Nope, still have the same problem.

So on my folders in recovery, I have a external-sdcard and a sd-ext file. Neither will see the files on the micro sd. Can anyone help?

---------- Post added at 04:59 PM ---------- Previous post was at 04:58 PM ----------

Also, if I try to mount the external card in recovery, it says E:Unable to mount '/external_sdcard'
[Asus Transformer TF700] buhohitr:
While in TWRP, have you tried to remove the card then reinsert the card wait like 10sec and see if it mounted?
[Asus Transformer TF700] Monkeydias:
I tried booting into recovery with and without the card in. Not to worried about it anymore though. I finally got it to work without mounting the card. I was trying to follow the directions in one of the previous posts about backing up to the external card but I just backed it up to the internal card and it worked that way. All is now right in my world, tablet wise at least. Thanks.
[Asus Transformer TF700] borgmanjayce:
I'm buying myself a Infinity on Thursday and I was recommended to download this app by someone who posted in a thread that I started yesterday in the General section of the TF700 section of the forums and I was wondering that if you were to use the whole of a microSD card as the /data partition, would that mean that you wouldn't be able to use it to store things like videos and MP3 files in seperate folders?
[Asus Transformer TF700] Monkeydias:
As far as I can tell, you can still use the micro SD card for anything. I have a 32 gig card that I partitioned into 2 gig fat 32 and 27 gig ext 4. When I loaded up data2sd and installed all of my apps I still have 24.5 gigs of space available. Plus, you can still use the internal memory and the other partition of the micro sd card.
[Asus Transformer TF700] borgmanjayce:
Thanks for answering my question for me.:good: It's just that using an entire MicroSD card for the /data partition sounds a bit extreme, so I'll probably go with 5-10GB for the /data partition on a MicroSD card and use the rest for other stuff.
[Asus Transformer TF700] MartyHulskemper:
As Monkydias said: your entire microSD card is available for data storage, essentially -- it's two partitions are mounted in two individualy accessible mount points. The second partition (the EXT4 partition) is to be accessed as your main /sdcard0 and your FAT32 partition is seen as 'the' microSD partition (easily seen in, for example, Total Commander).

The one difference you will have to take into account is the way you actually use the storage, and specifically the amount of storge space you want or need to be accssible from Windows machine: Windows only sees the first FAT32-formatted partition (out-of-the-box, admittedly, several rd party utilities provide read access; write acces may pose a data risk!). If you need to be able to transfer, say, a movie or two to buffer them onto your 700, you'd easily use around 3 GB for not-so-high resolution encoded downloaded fluff, meaning you'd do good to have a relatively large(r) first partition.

I work wirelessly, currently, so I have the standard recipe of 2/57.

ext4-partition dissapeared after using data2sd

I had an Asus TF201 with Data2SD (Sandisk Ultra 64GB). My GF threw it onto the floor, so the tablet is totally broken now (thank god she has an insurance for this!).

Now I bought a TF700 and I want to use Data2SD again.

The problem is, the ext2-partition went completely away. The PC shows the card as 8GB-card

I formatted it with Mini Tool Partition Wizard. Before using Data2SD on the TF201, both partitions (FAT32 and ext2) were visible.

Now the ext2-partition is gone. In Minitool partition Wizard, only the 8GB FAT32-partition is visible anymore. Also Windows says the card has only 8GB.

I already have tried some low-level formating tools, but this did not help. These tools seem to only see the 8GB of FAT32, the 56GB ext2 seems to be gone completely.

Is there any possibility to get back the 56GB ext2-partition?

Edit: After using the tool 'SD Formatter' and rebooting the PC, the sd-card has its whole capacity again. Even in 2013, a reboot cannot hurt :)

I'm stuck. I formated a 32GB microSD into two partitions, an 8MB FAT and the rest in EXT4. Both are primary and the EXT4 partition is active. I flashed CROMI 3.4.1 after a full wipe and without rebooting flashed sbdag's CROMI patch. Now I'm starring at the Nexus boot animation. What did I do wrong?
[Asus Transformer TF700] smalis:
It becomes a storage area, just like an external sd card. I don't think removing what is in there hurts, but I left all the data and android stuff alone, just to be safe - I just moved or deleted stuff I had put in there.
[Asus Transformer TF700] Darnell_Chat_TN:
Follow these instructions.

They worked for me and I did not put the files on the Fat32 partition, I used the internal storage "sdcard" space for all files and was able to do it all without any issues. I use CWM Touch Recovery.

The lag when installing an app is already greatly reduced with the ROW scheduler in the kernel. On a fast microSD card it could be even faster.
[Asus Transformer TF700] BossMafia2:
I read that people are seeing around 1MB/s for random write with this? I just bought a the SanDisk Ultra 64GB card, and am only getting .45MB/s random write, with 19.97 Seq Read, 4.21 Seq Write, and 4.2 Rand Read.

I'm on the CM10.1 nightly if that makes any difference at all. Should I be getting high results here? It still seems a little laggy...
[Asus Transformer TF700] buhohitr:
Have you disabled journaling?
[Asus Transformer TF700] BossMafia2:
Shoot, and totally forgot to do that. That should do the trick?
[Asus Transformer TF700] buhohitr:
disabled journaling should double your random write score.
[Asus Transformer TF700] ariadnejro:
Yes, but if you have a forced or random reboot with journaling disabled the ext4 partition can become corrupted and the tablet can even refuse to boot normally. In that case you need to use the e2fsck command from a linux console. I have had this annoying issue several times and now I have journaling enabled again although with lower random write speeds.
[Asus Transformer TF700] Ali I Hagen:
Not quite sure what I did wrong, but I followed all this steps. I'm not blaming you for my incompetence, your steps works fine. I was able to boot with Data2SD, but I had some hickups.

- First off all, I'm on CROMI 3.4.0, running om my TF700.

- I dedicated all my external SD card for for ext4 (with boot ticked), minus 3GB for FAT32. Could read all zip I had on external SD inrecovery. Using a Lexar Class 10 card.

- Made a back with system and data in recovery. Flashed mountdata2sd.zip and restored my back. Followed up with CROMI data2sd patch.

- After the first boots it seems like I had done factory reset and booted a clean install. You know, the screen which asks for log me into my Google account.

- Anyhow, I tried to play around, and the tablet seems to be snappy, expect several times when it doesn't respond to my touches. Like it is freezed for several seconds. Browsing is pain the ass.

Any tips what I did wrong? I have restore my backup in recovery and kind of removed Data2SD mod, and things are running normal again.
[Asus Transformer TF700] buhohitr:
When you're on data2sd, install androbench and test your sdcard then post the results. It's not normal after you flash mountdata2sd then restore your backup and you see the factory setup system!! you should see your backup setup.
