Froyo A2SD+ SD card corruption

Tons of new ROMs coming out now based on OTA and adding A2SD+. But one big issue. Quite a number of people have reported problems with corruption of their SD cards when setting the Desire into Disk mode and connecting it to a PC. I've read it the first time here
http://forum.xda-developers.com/showpost.php?p=7463184&postcount=348
and I can confirm it is reproducible.
Regardless if connecting to Windows or Linux, the card gets corrupted. It does not matter if you properly eject the drive. The Desire will respond saying the SD card is Read Only, and the only thing that one can do is to repartition it to fix the card.
I don't know what A2SD+ application everyone uses in their ROMs but I expect it's all based on some common version like the one put in from ieftm. As this is a serious issue it would be great if all you ROM cooks could look into it and try to fix it. Alternatively it may be a good idea to produce non-deodexed versions that save a significant amount of memory when installed normally without A2SD+.
Thanks for considering

I have this problem aswell its a bit of a nightmare there are a few files on my sd card that I can't even delete using andexplorer or my pc. I think the only way would be to remove my card and format it. I have never had this problem before only when I started using the 2.2 rom.

Noticed it before, i took the SD card out and put it into a cardreader, couldnt do anything in windows, said it was read only. Access via USB cable worked though.
Not that much of a issue for me, I mainly transfer files via Wi-Fi anyway, but I guess thats the explanation for the read-only behaviour.

Happened to me today, however I restarted the phone and everything seems okay now... :/
edit: nope, connected the phone again, chose "charge only" and then disconnected. The notification about my card being corrupted occured again, tapped on it and it went away... Dont know what to think..

I have the same problem .. And now it seems like the SD card is totally corrupted. Its not even possible to do a format

Okay thats it... Doing the titanium backup, nand backup and flashing some rom w/o A2SD+... :/

Out of curiosity guys, did the corruption of the SD card occur to the stock SD card that came with the Desire? I had the same problem with the stock card..
It seemed to unmount 3 or 3 times over a week and the next thing I knew it totally died and could not even be reformatted.. Happened on stock 2.1 that came with my Desire.. after I swapped to me own class 6 8gb Transcend I never had the proble again.. Just gonna upgrade to 2.2 now.. *fingers crossed*
Oh and yes.. I use A2SD+ on Modaco's 3.1. But that was after that card got corrupted..

I'm using card that came with the phone.
I'm going to try another Froyo Rom, just OTA rom rooted and we'll see.
Edit: I made my ext3 partition with ROM manager, if it makes any difference...

God dammit!

Yes its the card that came with the phone .. but it happen after i created the 512MB EXT3 Partition ... and I'm running this ROM : http://ip208-100-42-21.static.xda-developers.com/showthread.php?t=741775&highlight=official it doesnt even use A2SD+

I dual boot my pc with windows 7 & ubuntu.... windows 7 scan and fix has repaired mine numerous times

I have class6 A-DATA 8GB and no problem. But with my last G1 i haved same card and with swapping goes to hell... I now correctly unmounting and disconnecting mobile from PC, after i save from PC to card. Flash have problems with writing.

This looks like a serious problem - it happened to me twice already. Devs, please have a look at this!

I have also had similar experience, SD card corrupt, yes it was the original card that came with the phone, EXT2 partitioned and using APSD+
Now why this happend is a mystery, but something I noticed when I tried the SD card in the PC - it was recognized, but said it must be formated, so I tried but it only saw it as a 32mb capacity!!! (it still would not format though - failed format..and since is no longer reconized at all..)
But, this made me think it "MAY" be something to do with the fact that when I did the Ext2 partition I seem to remember it also created a 32mb swap partition, or using Ext2 instead of Ext3. I have since learnt that it is advisable NOT to created a swap partition, so with my new SD card, after more reading about Ext partitions etc, I have only created only the Ext3 partion as I understand this is better than Ext2 and is less prone to corruption, and no swap partition and have had no problem since!
See this excellent post :- http://forum.xda-developers.com/showpost.php?p=7458565&postcount=8
It would be interesting to have some input from one or two of the developers with knowledge in this field to get an idea why this happens, and how it can be prevented.
It is also possible the the SD card was going to become corrupt anyway... with or without the help of Ext? / APSD+ - it does happen!

my sd was corrupt using a 512MB ext3 partition without swap partition in SD card :/

Try in windows: start > run > chkdsk x: /f
where x = desire drive letter.
I believe i did this in recovery mode > mount usb.

That's what happens when you don't want to use Froyos own A2SD implementetion because "widgetz doesnt workzz on dat."
Apps are not meant to be on an external EXT partition.
Wait until ROMs like CM have built in A2SD+, these hacky shell scripts can cause serious problems for the SD card.

Windows can not access EXTx partitions. As such is unfortunately not possible that it could possibly repair a broken SD-ext partition A2SD+ uses.

I can confirm the corruption without any APSD+ ROM
I had a Stock Orange FR 2.1 ROM, and the 4Gb card that came with the phone get corrupted definitively (recognized as a 32mb capacity too, it has something to do with the Cylinder-head-sector combination).
Anyway, I'm going to try APSD+ with a class 2 PNY 16Gb, and tell you then if I get a corrupted card.
FYI, the Sandisk warranty is applicable for the original card: replaced in 5 days

I got some problems too with corruped files on my SDcard and had to format it. I'm thinking that from now i'll only mount my card to pc in recoverymode... maybe that is safe to do?

Desire Crashing frequently(possibly SD related)

Im using a SCLD GSM Desire rooted. Ive used Gingerbread versions of Oxygen, CM7, and currently on MIUI XJ but all freeze up on me often(almost daily) and battery pulls are required to revive.
The freezes do not happen with my 2GB Samsung SD card that came with the phone, but i have used 3 brand new Sandisk 16GB Class 4 SD cards and it crashes on all. This is regardless of whether i have Apps2SD enabled or not. I have looked for last_kmsg after the crashes on CM7 and Oxygen, but the file is never present after a battery pull, if i reboot normally i will get an old last_kmsg file from a few months back.
Was transferring about a gig of music to my phone currently on MIUI XJ 1.12.2, and after i unmounted USB storage it froze up and crashed.
The SD card im currently using was bought at a Virgin store, so im sure it wouldnt be a fake. I hope someone can help troubleshoot, im completely out of ideas!!
Thanks a tone in advance!

which version of MIUI-XJ ie.. A2SD or XPart or D2W?
You can try the following:
1. take nand backup, titanium backup & miui backup
2. download the full rom
3. full wip/wip cache/wip dalvik
4. flash the rom, if you are using cm7r2 hboot you might have to flash market cache fix.
5. let the rom reboot automatically and then let it settle for 15-20 mins
6. go to super user and make sure you enable ROOT permission ON.
7. power-off and power-on, restore your apps.

Thanks for help, appreciate it. I'm running the apps2sd version. Will flash according the method you have suggested. Since I'm on apps2sd, any reformatting/repartitiin you recommend?
Right now for the 16gb class 4 card I have a 1gb ext3 partition created using gparted.

You partitionend your SD card with an FAT32 partition and an EXT partition. If you partitionend in that order and set both partitions primary, you are ready for A2SD/A2SD+.
But please use "A2SD" if you are talking about the script which moves apps automatically to EXT partition, because with "app2sd" you could also mean the FroYo-App2SD and this would be very confusing.

Thanks for the help guys. I repartitioned and reflashed miui according to the procedures you'll mentioned. So far its been running fine, except that I had to use the terminal to reinstall a2sd yesterday, but still no crashes.
So far I have not put any music on the phone since last time it crashed when I filled up the SD. Now that I'm certain the installation is clean after using it for the past few days, ill go ahead and fill up some muswic tomorrow and will post back here.

So the phone crashes everyday now. Noticeably after I enabled a2sd amd moved dalvik.
Need to perform battery pulls to revive the phone and there is no last_kmsg after a reboot.it really kills me everytime I need to pull out the battery, hopefully someone can help troubleshoot!

I have the same problem. It's do not freeze only with stock hboot

Since I'm rooted on custom rom, any way to use a stock hboot now?

yes, you can use any rom with stock hboot. but you will not have much memory for applications

just checked, im on stock hboot.
do you have any other ideas ?

After failing to get 3 of my 16gb sandisk cards working, I tried my Samsung 2gb that came with the phone. This card is working flawlessly for the past month (or however long its been). I'm using a 512mb partition with apps and cache moved to SD with zipalign running and its never crashed.
Does anyone have any ideas? Can't really load any music into such a small card

I have a similar problem.
My phone crashes every time I browse fast trough my picture gallery (I have a lot of pictures) or I use an app that accesses the SD card continuously for several minutes.
For instance, it happens when I do a batch backup with Titanium Backup for all my applications.
I tried the official ROMs and custom ROMs (Cyanogen, DevNull) but the problem persisted.
I sent the device to HTC and they replaced the mainboard.
I tried then the latest official ROM and I faced the same problem.
I switched again to Cyanogen and the same problem appeared.
I have to mention that all this time I used a 8GB SD card (I tried several different cards with the same result) and no App2SD.
Now I'm using the card delivered by HTC together with the device and the problem is gone.
This card is only 4GB (the brand is Samsung) but it seems to work flawless.
My advise is to try a 4GB card and see if it works.

So many bugs... don't know what to do!

Hey everyone ! First I swear I don't post this because I'm too lazy to make a proper search, I've been trying to solve my problems for two days...
Ok, I'll try to sum it up. Sorry if my english goes wrong at some point, I'm french.
Having problems with my micro SD in my Desire, I bought a new one, a kingston 8go, class 10.
My desire was under CM7, was S-OFF with a modified HBOOT. And except from bugs due to my SD (sometimes it would not be recognized), everything was working.
After installing the new micro SD, i did some manipulations: wipe, reinstallation, change of radio/RIL/kernel, and unfortunately ended up with no recovery and others bugs. So I decided (at one point I did stupid stuff) to reinstall RUU aaaand as I was S-OFF with a modified HBOOT, I bricked my phone. BUt after some hours and thanks to the forum, I managed to put back a RUU.
Then I did everything properly: ROOT/S-OFF with revolutionary, wipe, micro SD partition, and CM7 installation.
THen it was hell: I tried everything from regular install to legacy2ext and SimplytoExt etc every time it's really unstable. First the all thing is slow, then I can't flash the google apps, no matter what I try. If I install an app from the market, sometimes it works, sometimes it makes the phone reboot from the boot animation, sometimes it can't install etc.. Google maps was especially unstable.
THen, 10 or 20 manipulations, formatting, reinstallations later, I decided to check other rome, like Oxygen or milwild.
On my last Milwild install, everything is fluid but I can't install a single app (it's just stay on "installation" forever) and I can't wake up the screen after the phone goes to sleep.
Last but not least, my usb charger seems to have transfer problems. It's way to slow and the speed is not constant. During large transfers, comes files go corrupted. Am I usb bricked or something? I tried with another micro SD and it's the same problem;
So here I am, I really don't know what to do more? Any help?
Thanks a lot for your eventual answers!

Seems that installing a RUU solve all the problems for now, I wonder what in the process of putting a custom ROM could have caused so many differents and random problems. I'am doing the all process again to see if I can do it properly.
And again, I installed a custom ROM with CM7 hbott: impossible to download any app and the camera crashed. Any idea?

1. Don't use any D2EXT scripts with Cm7, obviously that's what caused the issue. If you NEED more space (even with cm7 hboot) try using DarkTremor's A2SD.
2. Before you flash a new ROM, do a FULL wipe (either from fastboot or recovery) - erase boot, system, userdata, cache, sd-ext (make sure you have an EXT-n partition on your sd-card, best program to use is gparted)

Desire is designed for class 4 SD card. Although some class 10's will perform at class 10 levels, many do not because of this. Kingston Class 10 being one example (I have one).
My kingston class 10, in Android, performs at class 6 speeds. Which would be ideal, but my class 10 Kingston was slower with data2sd than my class 4 sandisk.

I only was using this script to put the apps on the ext partition and I removed it. It's obviously not the problem since they stayed after a clean install.
I always fo a full wipe, I even formated all the partitions and my EXT partition is there and well aligned.
Here I am: I managed to "stabilise" with a gingerbread RUU, rooted and S-OFF with revolutionary.
I used RM recovery (with USB brick fix) and it seemed to help. I don't have any USB transfer problem any more.
The RUU works like a charm.
Then I tried again to install two customs romq, without any script or modification:
-on Milwild, I have still this "deep sleep" problem. I can use the camera, but I can't install any app from the market. It's stays on "installation" forever.
-On CM7 (I put the CM7r2 HBOOT with it) it starts well: I can install google maps. But then I try to open it and it freezes. Then I try to mount the FAT32 partition on my computer and it doesn't work. The cellphone also freezes when I try to reboot (there is the wheel, turning and turning, but nothing happens). SO I forced reboot, and then, google maps had just ... disappeard. I think my phone is haunted...
Isn't it strange that my cellphone is perfectly normal under RUU but can't bear any custom ROM???
I think I'm gonna go back to the RUU and try to use another SD card but I'm sceptical. If someone has a miraculous idea to share, I'll take it!!!
Thanks again

Well, rootSU, it seemed that you found the answer. I put another class 2 sd card and it seems to work again! I just spent hours on this for nothing... The strangest is that the class 10 card work perfectly when out of my phone...
Any advice about a good class 6/8/10 that could improve the performances without crashing like this?
EDIT: last question, I used the app2sd script you introduced, but I can't install any app with it, it says that I've got unsuficiant stockage space Oo.

I use.my class 10 Kingston and it works perfectly as a class 6. Plus its pretty future proof. Just no.good for data2sd.
Should work fine for everything else though

Well, mine didn't worked at all, except the RUUs...strange! I have fully configured my class 2 SD card with simple2ext (only app on the ext partition, not data) and it works.
As I'm tireless, I'll try to put all this via nandroid on my class 10. If it could work like a class 6...

What did you use to partition the Kingston?
Sent from my HTC Desire using Tapatalk

I partitioned it several time, with gparted and recoveries. I'm a bit worried about some part of the hardware managing the connection with the SD card that could be partly broken. I decided to change my first SD card when I first saw a "you need to put an SD card" when I try to take a picture. I had problems with files disappearing from the SD and reappearing. Also I lost some applications that I couldn't appear. I figured the card was dying.
Then I put a new SD card, faster and with larger capacity and everything goes wrong;
Then I put the old one back and... for now, everything works.

[Q] SD Card problems

Hey everyone,
I've been looking everywhere to get some help with a problem I have with my 32GB SD card.
I'm using an Xperia Play (R800) rooted, unblocked and bloteware removed. Whenever I try to move files, I use one of 2 methods:
1) moving files by connecting the phone to my PC via USB cable and dragging files
2) unmounting the SD card from the phone and use a card reader to move files
In both cases, no matter how I try or how I move the files, eventually the phone will either freeze / freeze + reset / reset / or everything combined several times. Once the system boots up again, it restarts itself several times while trying to read the memory card.
This is really frustrating because it happens to me for the past 4 months, ever since I bought the phone and tried working on it. No matter what I try to do, I always end up with this problem, which eventually leads my SD card to randomly delete files. This includes music, transferred PSX games and such. It's really bugging me, and I really need some help.
If anyone can help me out, I'd deeply appreciate it.
Thanks a bunch in advance
NOTE:
The card was later formatted to 2 partitions: FAT32 and EXT2. This DID NOT help, so re-partitioning my card won't help. Think of something else.

Repartioning your sdcard over and over can result to data loss. Why did you have 2 partitions? You should only be using FAT32 as your primary partion.

I only did that once, and it doesn't have anything to do with the data loss as this happened before I partitioned the SD card. I have 2 partitions for Link2SD app. And even if I do have FAT32 as my primary partition, it still deletes my files at random...

I have 2 partitions for same reason as you Link2SD! That should not be a problem.
Couple of questions
(1) Is this a new SD card and have you used the card before on other phones (Could be a fault with card try different SD card)
(2)Have you been on the same rom since this problem started (If yes i would try a different rom could be a software problem.)
I would try these options to narrow down what the problem is seems like you have tried all the partition and formatting options already :fingers-crossed:

To answer your questions:
1) This SD card has not been used on other phones since this is my FIRST smartphone (took me a while to move to the next step )
2) I never use roms, only the default stock rom.
I find it hard to believe that the SD card is the problem, but what do you think?

I think only way to know if SD card is to blame is try another one,there are apps on Google Play that can test SD card but I don't know how reliable these are.Also you said you deleted bloatware did you delete something you should not have?It would be good if you could try another card then you would know for sure a smaller SD card just to test?

Well, oddly enough the problem WAS the SD card all along! I've been trying a new SD card for the past week and everything went smoothly.
Funny, but the solution was only to replace my SD card.
With that in mind, I'm changing my question. I guess there have been many posts about it, but I'm going to ask this anyway:
What would be the best SD card for the Xperia Play? The bad one I used recently was a SanDisk 32 GB Micro SD card, and the one I'm using now is a small sized 8 GB.
Can anyone help me out on this one?

The best sdcard for the xperia play is a Sandisk class 4 or 6 sd card. Preferably stick with the class 4.

Link2SD - Not Mounting 2nd Partition after over a month of it working fine

Have been using Link2SD now for over a month without any problem.
I have a 64 GB micro-SD card formatted with 2 partitions. One is the fat32 partition for storing my own stuff (accessible through file explorer), and the other is an ext2 partition that is meant for Link2SD to "link" apps to. Both partitions are roughly of equal size (though in hindsight I would have like to make the ext2 partition smaller). I formatted + partitioned the SD card using MiniTool partition wizard in Windows.
As of yesterday the 2nd partition is not being mounted any more. I get the error as in attached screenshot. This error comes after Link2SD asks me to select what the file format of the 2nd partition is.
Because of this, all of the apps that are linked to the SD card in some way are now showing as not installed on my device (most are games, but one is a magazine-reading app). An attempt at reinstalling 1 or 2 of these apps through google play results in an error saying something like "there was an error installing this app".
I tried to search the forums on this error but most people have similar issues only when they are ~starting~ with Link2SD. I haven't found anyone who has the issue like this after using Link2SD for a bit of time...
I am wondering if there is a workaround to this. It would be nice to get those apps back onto the device at the very least (I have 4 GB of space to spare...), and at the very best get everything back to working condition again.
(note: I started to notice that certain apps started naming the SD card as a bunch of symbols instead of "SD card" as they usually do.....not sure if this is related or not)

*bump*
Should mention that I"m running a rooted device with stock ROM (took out many of the built-in apps).
I am debating whether to unmount the SD (physically take it out), and reformat the 2nd partition to ext4 or FAT32 and try again with Link2SD
What I'm afraid of is losing all those apps and not being able to reinstall them again....(as I am already getting errors with this in Google Play)

I've been having issues with it for a while myself. Sometimes after a reboot, a whole lot of apps disappear. I give it another reboot and they come back, but it's a pain in the arse because then I need to manually go place them back onto my home screen.

I have tried multiple reboots....no such luck.
I'm reading elsewhere that the culprit may be Link2SD itself. Have emailed the developer (hopefully they respond).
The ext2 partition on the card is officially or unofficially fried. I really can't see anything on it (tried several linux file system viewers). I guess I'll keep the card mounted (with half the space technically gone) until there happens to be some way to deal with this issue....

I tried Link2SD with 3 different SD cards.
One was a test (4 GB card or less, can't remember now), to make sure the program worked.
The other was an 8GB card. Which I eventually swapped out for...
...a 64 GB card.
I had manually partitioned the 8 and 64 GB cards prior to using them in Link2SD
I also re-partitioned the 64 GB card a 2nd time when Link2SD (and therefore my tablet itself) stopped seeing the 2nd partition on the 64 GB card.
This "breaking" problem came up on both the 8 GB and 64 GB cards.
So one of the following at fault: my tablet, 2 different SD cards, or the app itself.
I am inclined to believe it's Link2SD as the reviews on the app store say similar things to what my problem is.
