Disregard! It is fixed with a clean install of everything, and formatting data etc. I now have a new issue listed in the post after this one.

I think that I might have a have an issue with My .data2sd. I am running a SanDisk class 10 64gb on chromix 5.04 using that_kernel v5 oc on tf300t. I have 30gb(not exact!,but close enough) for space and 30gb(not exact but exact!,but close enough) for data. In settings/storage it shows internal storage 29.52 and microsd shows 30.44. I

have the 32gb version tf300t.

Everything is really fast and the post above this are my performance scores. The problem just became apparent when i tried to download a torrent movie. Before data2sd i would download my torrents to microsd because if i downloaded to internal storage then the tablet became unusable until the download was finished. Downloading to microSD before data2sd made it so i could browse the internet at the same time with little lags here and there.

Now with data2sd i am unsure where i should download to, so i chose removable/microSD/ and this is where the problem became evident. The tablet started lagging, freezing etc. So i looked to other places to download to and noticed something strange and may possibly be an issue. I dont have sdcardi , i do have emulated, sdcard0,and sdcard1 though. Those are the only three folders under storage/ . In root explorer sdcard1 is empty, sdcard0 has the normal files like android,data,music etc. Storage/emulated has 0 and legacy.

I have datai in root and it does contain the file system plus i have a sdcard folder . I decided to try downloading a torrent to that sdcard folder as root sdcard/download. The results were much better but sometimes a page would freeze up but i could just refresh the page. When downloading to removable/microsd/ the tablet would lock up and lag , freeze.

So, is there a problem with my file system? The tablet is now lightning fast on balanced mode, on performance mode its crazy! I click something and it immediately pops up, just look at my scores above this post.

I do a lot of movie downloading and would like to know which folder they should download to. Hope you can shed some light on my situation, thanks!
[Asus Transformer TF700] mescalinedreamz:
I had a problem with data2sd in the above post. I fixed the issue of a lagging tablet while downloading a torrent or large file. I installed stock asus rom, reinstalled twrp and formatted data after i did a factory reset. Oh, and i reformatted and repartitioned the microsd. Then i installed chromi 5.04 with data2sd with that_kernel v5 with cache2sd and fsync off.

Now i have a new problem. I can not browse the internet and download a torrent simultaneously. I get a timeout in the stock browser whenever i try a webpage. I have tried limiting bandwidth for both uploads and downloads, i have tried limiting the amount of seeders too. I have cable internet and can download torrents at 1.5mb/s at the highest.

I did not have this issue when i wasn't using data2sd. I would download directly to microSD and have to deal with some lags here and there.

Please help! I love data2sd, the whole reason why i use it is because i download lots of torrents. Is there a mtu script? Or some other script that gives priority over one app only that is causing the problem?

Thank in advance!
[Asus Transformer TF700] fantabrothe:
hi mates, just wondering what's the best i/o governor setting to squeeze performance with this mod, now i'm on latest chromi with thats v5 kernel, governor is default row and 4096 readhead......is this the best choice or someone can suggest something else?
[Asus Transformer TF700] Lummers:
Internal Mem

So I'm a little lost on the mod

What happens with the internal memory?

Gone?

I was planning on trying this out with a Patriot Signature LX Series 64GB SDXC Flash Memory Card Class 10.

Just wondering what happens to the internal memory and if that card above will be sufficient enough.
[Asus Transformer TF700] sbdags:
Its still there for media use if you use a kernel like that's or hunds with data2sd support.

Make sure your card has at least 20MB/S write speed like a class 10 uhs-1 does.
[Asus Transformer TF700] Lummers:
Perfect that's the spec that I was looking for.

I'm on the Cromi right now with Hunds, I can just reflash and setup data2sd

Have people notice a huge different with this I/O fix?

It's driving me boinkers right now every time Google App Update occurs.:silly::silly::silly::silly:
[Asus Transformer TF700] hardslog:
Are there any modifications to the kernel that need to be done to make Data2SD work? It seems to me there are just changes to the ramdisk. Is that correct?
[Asus Transformer TF700] _that:
Correct. Just some different mountpoints basically.
[Asus Transformer TF700] hardslog:
_That, you are a gentleman and a scholar :)
[Asus Transformer TF700] Meneldur:
Certainly Data2SD gave me a new tablet.

I just want to know why all former internal sdcard content is inside sdcardi/0 and not directly into scardi

[Asus Transformer TF700] Vienna 1683:
Hi there,

I'm using the SanDisk

Ultra

Class 10 64GB microSDXC with the newest CROMi-X with activated ROM2SD-option. Is the microSD, which I'm using, a good card for this?

It's worth or would it be better to use for example the SanDisk microSDXC

Extreme

UHS-1 64GB? I'm asking, because I have no clue about it. Maybe the microSD-cardreader of the TF700 isn't able to use the advantage of better microSD-cards!? :confused:

sent from my ASUS Transformer Pad TF700 CROMi-X 5.2
[Asus Transformer TF700] sbdags:
Is the ultra the uhs-1? If so it is perfect. The extreme is known not to be compatible so don't waste your money.
[Asus Transformer TF700] Vienna 1683:
Yes.

It is the SDSDQUA-064G-U46A.
[Asus Transformer TF700] Essentrix:
sdbags after all this are you telling me the extreme card isn't compatible with ROM2SD??? That's what I'm using...:(
[Asus Transformer TF700] sbdags:
Yes it looks like it :(
[Asus Transformer TF700] wollac11:
Does this issue also include the SanDisk Extreme Plus microSDXC or does that one work?
[Asus Transformer TF700] sbdags:
Yes the extreme series don't appear to be compatible currently.
[Asus Transformer TF700] wollac11:
Okay thanks for that! I was thinking of purchasing one as they seem to be the fastest cards out there but I think I'll look to the Samsung 64GB Class 10 UHS-1 MicroSDXC Pro Card instead then. Cheers for the heads up!

Do you know if it is possible to use this mod with a 4.3 or 4.4 ROM yet? I haven't found any kernels which state they include Data2SD and work on CM10.2 or CM11/Omnirom KitKat. Is there a problem with support for later versions past 4.2.2 or do they just not exist yet?
[Asus Transformer TF700] sbdags:
I don't think data2sd works with CM4.3 but I tested ROM2SD with 2 different CM 4.3 roms and they worked fine with CROMi-X on internal and CM10.2 on SD ;)
[Asus Transformer TF700] wollac11:
Okay, is this just due to the lack of 4.3 kernels with Data2SD? What I mean is would it be possible to modify the RAM disk of an existing 4.3 or 4.4 kernel to get Data2SD working or is there more to it?

Thanks for the suggestion regarding ROM2SD but I don't think it will give me the setup I'm after. I really just want a 4.3 or better still a 4.4 ROM but without terrible performance due to IO issues and still enough free space for all my stuff. I have the 64GB model with a 32GB card and both are full. the Internal is full just with apps and games! My tablet is dreadfully slow. I just want to have my Apps and app data entirely on the SD and documents etc in the slower internal memory.

I really like CROMi-X and I used to use it for quite some time (and the old CleanRom Inheritance before it) but I wanted to use 4.3 (and now 4.4) and I understand that since it is based on stock we depend on Asus to bring us an updated stock ROM to be able to have CROMi-X on a 4.3 or 4.4 base. I appreciate your hard work though!
[Asus Transformer TF700] wollac11:
I've actually decided to switch back to CROMi-X so I can make use of Data2SD. I'm loving CROMi-X so far but I have not enabled Data2SD yet. My new 64GB MicroSD turned up this morning so I should set it up soon.
[Asus Transformer TF700] wollac11:
Having no luck getting Data2SD working at all. I have formatted my new Microsd card (Samsung 64GB Class 10 UHS-1) with an 8mb unformatted partition (#1) and then the remainder in ext4 (partition #2). I don't need a fat32 area on this card because I use Linux which can read the ext4 partition anyway and I will fill pretty much a full 64 with apps and games.

I then did a clean install of CROMI-X 5.2a and choose Hundsbuah's kernel and the Data2SD from the Aroma installer and then rebooted. No luck it just keeps failing to boot. It vibrates, shows the Asus logo for a bit, the screen goes black and then it repeats. I tired again with _that's kernel and this time I get the framebuffer console (with the Linux penguins) that claims to be setting up Data2SD but then after a few seconds it reboots back to the ASUS logo. This also repeats seemingly indefinitely.

Any ideas?
[Asus Transformer TF700] sbdags:
Yes that first partition must be fat32. It won't work otherwise. ;)
[Asus Transformer TF700] wollac11:
Okay thank you, I was thinking I could leave it unformatted as Mistar Muffin's instructions in the OP said:

I didn't want to have a fat32 partition because I wanted to use the full 64GB for /data. Why will it not work when I replicate Mistar Muffin's setup?

Edit: Tried repartitioning with a 4GB Fat32 partition and the rest ext4. It made it as far of the bootanimation now but the boot got stuck and it rebooted. It did the same another two of three times and then it stayed on the bootanimation and seems to be hanging indefinitely.
[Asus Transformer TF700] sbdags:
The CROMi-X data2sd is _that's implementation and requires a fat32 partition.

Is it hanging on a clean install?
[Asus Transformer TF700] wollac11:
Okay, is there a minimum size for the fat32 partition? And yes it hangs even after wiping everything but data/media (internal) and installing fresh.
[Asus Transformer TF700] Meneldur:
I had mine at 8 MB and it worked fine.
[Asus Transformer TF700] wollac11:
Okay, thanks for clarifying, it's obviously not that then. I am out of ideas now, not sure why it doesn't work.

Edit: Hang on a minute, that can't be right. I just reread your post as I am now returning to sorting out my TF700 after a while just doing without it because I didn't have the time and I noticed you said yours was 8MB but that cannot be right seen as the FAT32 filesystem only works on a minimum of 32MB.
[Asus Transformer TF700] wollac11:
I think I'll just chuck my TF700 out of the window! Even though I flashed the zip to mount the SD as /data first, the latest wipe cleared the whole of the internal data/media too. Everything from the 64gb internal memory and 64gb card is cleared. Not happy! It was full of stuff. Before someone mentions a backup, this was attempted several times but not possible as copying that much data from the TF700 fails after a couple of hours and it doesn't even cover a decent proportion in that time because the NAND is so slow!

Going to have to try and see what if anything I can recover in some way or another.
[Asus Transformer TF700] Meneldur:
Oh my, that's bad.

But... I remember recovering entire SD cards using 'photorec', a Linux utility you may install easily in your distro.

Remember that using a data2sd kernel switches partitions. So, you must flash Mistar Muffin's mount2sd patch (check post 2) BEFORE wiping caches since data2sd kernel kicks in AFTER the tablet boots and before loading Android. Wiping from recovery occurs before data2sd changes anything.

And it's almost never useful to do more than a factory reset. There are just a few scenarios where you should wipe all the guts of your slate.

Mnldr@xt910_xda_premium
[Asus Transformer TF700] Meneldur:
Will data2sd support 4.3 kernels anytime soon? CM 10.2 is way faster than CROMi. Data2sd would really open new grounds.

Mnldr@xt910_xda_premium
[Asus Transformer TF700] wollac11:
This is what I was after too but no one seems to be working on one. It this point I think people may as well focus on 4.4. Cm11 / Omnirom 4.4 with working Data2SD would be great!

---------- Post added at 03:12 PM ---------- Previous post was at 03:06 PM ----------

Yes it appears there was some error in mounting the SDCard that last time with Mistar Muffin's mount-data2sd zip and so the actual internal memory was wiped rather than that. Still odd that Data/media went as well though. This didn't happen the first few times I tried it. I am wondering if there is some issue with my TWRP image.

I have some data recovery software but thanks for your suggestion. The issue is how I will be able to mount the internal memory properly so I can use any sort of data recovery software on it. Under Android it will use MTP and so does not give direct access to the filesystem and from recovery, usb mount does not seem to be possible on this device.
[Asus Transformer TF700] Meneldur:
Don't worry. Photorec and Testdisk both only need the card inserted in your computer. They'll do the rest.

Mnldr@xt910_xda_premium
[Asus Transformer TF700] wollac11:
Yes but the issue is not the SDCard but the internal data (/data/media). I already have all the data that was stored on the SDCard on my PC.
[Asus Transformer TF700] AndroidFTW11:
I'm going to apologize in advance because I'm sure this had been and before, but I read through a few pages and couldn't find an answer. My computer does not have a CD drive. Is there a workaround to this?
[Asus Transformer TF700] sbdags:
For what - using gparted?

If so use a live usb boot image instead. Go to the TF700 CROMi-X link in my sig and details are on page 2.

window utility for ext partition

I ran into this utility it allow you to mount an ext partition in windows and see and copy your files in it.

I guess the same is also available for Mac (not free)

Windows isFREE but you need to register

look for: paragon extfs in Google
[Asus Transformer TF700] mattbooty:
Is there any way to copy files off the sd card on a data2sd install without booting? I have been running data2sd for the last 6 months, suddenly my tablet won't boot off the sd card. It boots fine from the internal though.

I have files I really would like to get off the data2sd install though. Is this possible in any way?

Thanks
[Asus Transformer TF700] berndblb:
I believe there are Linux distros that can mount and read external ext4 partitions - no idea if there is something equivalent in Windows, but I don't think so. I just set up my laptop as a Windows/Linux dual boot because so many things related to Android are easier from a Linux environment, and I have to say: It was a breeze to set up.

Edit: I just tried it on the Zorin distro (and I know you Linux purists - you will wrinkle you noses because it's so Windows, but hey - give me a break! I'm just starting out! LOL)

As you can see in the screenshot it recognizes all three partitions of my rom2sd microSD just fine (two of them being ext4) with some files and folders obviously not accessible. But enough to give it a shot I would think. Find someone with a Linux laptop and just give it a try.
[Asus Transformer TF700] _that:
Sure, just mount it in any Linux distribution, or even on your tablet. But if you can't boot off it, the filesystem may be corrupted, so you may need to run fsck before, roughly like this:

su

mkdir /datax

fsck /dev/block/mmcblk1p2

mount -t ext4 /dev/block/mmcblk1p2 /datax

Then grab your files from /datax.
[Asus Transformer TF700] mattbooty:
I apologize for my lack of terminal knowledge, I'm trying what you suggest but when i run mkdir /datax I get an error that "mkdir failed for /datax, Read-only file system".

Any thoughts? I don't have access to linux so I wanted to try this first.

Thanks again to all replies

---------- Post added at 08:21 AM ---------- Previous post was at 08:01 AM ----------

Just to update, I tried /data/datax and it did create that folder, but then failed on the next line with "fsck not found"

I tried some windows programs that claim to be able to mount ext4 as well and they couldn't see that sdcard... i'm thinking the card is corrupt and those files are gone. nothing life threatening but would have been nice to get them back.

Thanks for your help!
[Asus Transformer TF700] mattbooty:
OK, so i was able to find a program from diskinternals that will read the sd card! My problem I have now is I cannot find where the data is stored... It sees a /data partition, which I am 99% sure is my sd card (the size matches), and there are folders like "dalvik-cache", etc which I recognize from the android world... any thoughts on which folder would contain the data that is visible from inside android?

UPDATE: I found it, it was media/0

Thanks to everyone who helped... if anyone else is in my same situation, I used "linux reader" from diskinternals to do this!

sandisk extreme pro

I was bored today so I decided to try this mod again using a Sandisk Extreme Pro 16Gig card. it is now working. I am running CRomKK now(CromX previously) and wonder if it made a difference? The card is actually the same card i was unable to get working previously. It is the same right down to the partitions. All I did was plug the card in, reboot to recovery, and reinstall (with data wipe/format) CRomKK using the Data2SD kernel.I know it is using Data2SD because i now have a /sdcardi and my androbench score is .62 MB/s (fsync on).
[Asus Transformer TF700] allendj81:
I've been trying to make the 2 partitions necessary on SanDisk ultra class 10 wih gparted, and for the life of me i cant make the partions!! What do i name each partion? Im naming them as follow:

The primary 1 im not naming it anything. Im just making it 1gb in size, created as primary partion, and fat32 file system format.

The primary 2 im naming it /data, made it 30gb in size, created as primary partion, and ext4 format.

When i apply changes, partion 1 goes thru and partion 2 (/data) gives an error and doesnt finish applying.

Im probably naming something wrong but cant figure out what. Please show me the light.
[Asus Transformer TF700] sbdags:
You probably can't put a "/" in the name.

You can call it what ever you want it really doesn't matter - make sure you are using gparted to partition as per my guide. No other tools are known to work.
[Asus Transformer TF700] _that:
Have you tried to read the error message? Or does it only say "Error"?
[Asus Transformer TF700] allendj81:
Here are some pictures of what I get.

Dont know why is showing the second partition to be of an unknown file format if im selecting ext4
[Asus Transformer TF700] allendj81:
Yeah, I'm following your guide, using the Gparted. your guide shows specific partition paths for rom2sd only, right? it doesnt mention specific paths for data2sd but I figure is because it doesnt matter what we name them.
[Asus Transformer TF700] _that:
Looks like you didn't actually format the partition.
[Asus Transformer TF700] allendj81:
After ive configure both partitions I hit apply. The first partition goes thru but when trying to process the ext4 parttion i made, it stays processing for a minute and it gives that error in the pictures that i posted. Format before doing the parttions in gparted?
[Asus Transformer TF700] sbdags:
Can you post a screen shot of the apply error please.
[Asus Transformer TF700] allendj81:
Check out post #1940, I posted 3 pictures. The first picture is what the partitions look like after I try to make them (the fat32 goes thru, but the ext4 that i tried to make gives me an error) Then I click under detail about the failed partitions (that one that says unknown, and it displays the details about the error that you see on picture #3). Gparted is failing to do the ext4 partition. Another thing that Ive noticed is that when gparted doesnt give that error, it gets stock and cant do anything. I even waited to see if the gparted needed time to process the partition, but after 20 min I restarted my computer.
[Asus Transformer TF700] sbdags:
Sounds like the card has been corrupted somehow then? The reason I asked is the third screen shot appears to be an info window not the error message directly after if fails to partition.
[Asus Transformer TF700] allendj81:
I didnt post pictures of that message because it just said error and to contact support. There was no specific messages as to way it failed, it says to check the "details" for more info and to conctact support (picture #3 is what shows when going under "details").

Im reformating the microSD card once again to FAT32. I also download and set up the previous ISO image from gparted just to see if Gparted is the one giving the problem. Just to let you know again, Im doing 2 partitions using gparted:

1. 1gb in size, setting it as primary, and with fat32 file format

2. 30gb in size, setting it as primary, and with ext4 file format

Im using a SanDisk ultra microsdhc uhs-I 32gb, speeds of 30mb/s 200x
[Asus Transformer TF700] allendj81:
Got some pictures:

picture 1 shows how the partitions look like before hitting apply

picture 2 shows the error message that I get after hitting apply

picture 3 shows how the partitions look like after I press "ok" in the error message pop up (pic 2)

picture 4 shows how gparted crashed after trying to set up the same partitons and hitting apply (I then reboot my laptop)

Dont know what to do anymore. MicroSD card was formated to fat32 in windows before using it in gparted. using a Sony vaio with windows vista (intel pentium dual core)

Post the file you got when you clicked "Save Details".

[Asus Transformer TF700] Meneldur:
Hello everybody.

I searched for a complete answer but I didn't find one. I'd like to test DATA2SD with CM11 (or another KK custom ROM maybe). I've seen that CROMI/CROMBI use _that v10 kernel to offer DATA2SD but _that kernel's thread says it supports "init scripts for enhancements like DATA2SD", not D2SD directly.

So... How can I do to enable D2SD on CM11 latest nightly?
[Asus Transformer TF700] sbdags:
I also modded the cm11 kernel on CROMBi-kk to use that's init as well so you could just steal that as well as the /system/boot preinit scripts.
[Asus Transformer TF700] Meneldur:
Thanks, Pal!

I should know this by now but… what files/folders should I copy from CROMBi? Do I simply insert them into _that's zip?
