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?
My SD card isn't detected after reboot.
The device is stuck in the splash screen when the SD card is inserted.
When I reboot without the SD card and wait a few seconds to inserted the SD card then the device is booting normal.
Also when I enter the 3 color then the SD card with a correct nbh file on the root isn't detect.
I format FAT32 the SD card a couple of times without result.
What could be the reason why the device is detect the SD card during booting?

If you haven't, try using gparted to format it, or format it to another fs (such as ext2) then reformat again using fat32... had a similar issue using a 128mb sd card (a really old one) and fixed it this way...

The same result with a new SD card.
I think it's a problem with the device, could this?
The problems started last week when I removed the SD card without unmounting.
With the next reboot it wasn't starting. After trying many times I found the workaround with booting without SD card in, but I don't like this situation.
if you can boot without sd, boot, then insert the card and look if it is detected.
in this case try to format it from android.

Question, does the device seem to detect ANYTHING when you insert the microsd ??
check the logs.. (keyboard, FN + left custome key, FN+Right one to get back)
Press the FN+LEFT, and insert the card, check for logs on the screen about it...

Sorry, didn't notice you had a Polaris
So, you can enter bootloader. Without a SD, you get the SPL version i think.
With the SD , what happens ?
Second, start droid, wait a few secs, insert sd.
Start terminal, and issue the command mount, what do you see?

also try a umount on it just to make sure its not just a damaged file system for whatever reason.
I was using my 4gb sd card for apps to sd for my previously-rooted android phone, and had about a 500mb of it partitioned to ext3. I have since unrooted my android phone and put it back to stock, but in doing so, I lost the recovery console that would allow me to unpartition my sd card. Is there a safe program that will recognize the ext3 partition and remove it?
Gparted. You can use a live cd or a VM.
Hi there. I downloaded a free program call minitool partition wizard. Do a google search for it (I can't post links)
It has worked well for me with my SD card partitioning.
Make sure you back up the contents of your SD card before removing the ext 3 partition as it will delete all the contents on it.
could you please elaborate a little as i am a noob. like whats gparted? whats a vm? whats the process of doing what i asked? thanks for the help.
I don't know if Windows recognises it at all but worth a try really. Gparted is a live cd tool that allows you make partitons on a storage device. I think that VM refers to a Virtual Machine, using something like VMWare or VirtualBox.
guys please help. i used these softwares but none of these is showing my ext3 partition in the program window. just a 3.22gb of one partition on phone. the 512mb of ext3 partion is still missing and i dont know where to find it.
Well, since you really don't need the ext3 partition anymore, you could format the whole SD card from windows (do a back-up of the content on the hdd before, though). Then in Windows (I'm guessing you're using windows ), with the phone connected in mass storage mode, right click on My Computer / Manage / click on Disk Management and you should see in the list of the drives your SD card (pay attention to the size). Right click on the 512 MB partition - Delete volume... After that you should create a new partiotion, format it as FAT32... Or you could delete all the partitions of the card and create a new volume.

i did that. in disk management i only see a 3.22gb partition. (i have a 4gb card, so i 512mb is still missing). i cannot find the 512mb ext3 partition anywhere. please can someone help me to find a software or any other method which will be able to detect the ext3 partition as well ?
The partition may be corrupted. You can still try to use Gparted live cd - google for gparted-live-0.7.1-5.zip . It can also be installed on USB flash, check their site for instructions. Restart your PC and boot from the CD or USB flash then check your sd card. If it still doesn't recognize the 512 partition, you might be out of luck.

how could the partition be corrupted because i was using the ext3 partition to install apps when i had root. it was only recently that i have to sell out my htc desire and i unrooted my htc desire. unroot procedure was done successfully but the card is only showing 3.22gb, i-e, 512mb is missing. this may become an issue if the buyer does not want to pay for a 4gb card with only 3.22gb of storage. it should be around 3.5-3.6gb
A partition may become corrupted if you remove the battery from the phone while the system is still running (i.e. writing data on the partition), it is not unheard of. Do try the gparted solution mentioned before, though.

yes buddy i have tried the gparted solution you suggested before. even that is showing only 3.22gb of my sdcard and no mention of the 512mb ext3 partition. i dont know whether i am doing something wrong or what.... ???
Anyway, is there anyway i could recover that corrupt partition? Like can i ROOT my htc desire again and then try to format the ext3 partition from the recovery? i read somewhere there is a way to do that in recovery by giving some commands. and once i have recovered the ext3 partition space then i can UNROOT my htc desire again. DO YOU THINK IF I DO THIS ITS GONNA BE OF ANY USE? Please help me.
This might work since it worked for me. 4GB mysteriously disappeared from my 16GB card and neither Windows or gparted picked it up. The only way I was able to get it back was putting it in my phone and the Android picked it up. I did have to format my whole SD card but nontheless, I got all my space back. Hope this helps and if you have tried this then I can only guess that your SD card is buggered.

um actually, my sdcard IS in the phone this whole time as i dont have any card reader. i am connecting my phone with my pc in hard drive mode.
from within the phone, i have tried to format the sd card many times but the space does not go beyond 3.22gb..
Something seems to have messed the partition up. Have a look around on the web
Sent from my HTC Desire using XDA App
ok tell me if i root my cellphone again, will it help?
because there is a way to delete the ext3 partition from the recovery.
finally recovered my ext3 partition.
this is what i did.
1) rooted my phone.
2) enter into clockworkmod recovery
3) mount sd-ext (i guess it wasnt mounted that's why no app was recognizing it)
4) now windows was able to recognize the ext3 partition.
5) problem solved.

i had the same issue as the OP
Use a card reader and MiniTool Partition Wizard.
Delete all partitions on the SD card and create a new one that fills the entire SD
I got HTC Wildfire and i just installed RemPuzzle 2.83(which is great btw but that's not the point here)
and my CWM recovery is v2 or i don't remember.
i had v5 in my sd card.
i booted on my recovery(old version) and then i selected to install v5.
from v5 i selected to partition the sd card(options 4GB memory and swap 0) :silly:
it completed the task and after that the sd card is uselless.
the phone can't read the sd and my computer(windows) suggests to format the sd card but it cannot complete the task.
my question is
can i get the sd card working again or it's going to the trash can?
i don't care about the data inside,before anything was done i ha backup done to my pc.

Use clockworkmod v 5 to format the SD card or just re-partition again with a swap size
my phone can't recognise the sd card.not even in recovery.when i selected wipe sd card it says "skipped sd card - complete"
as an effect i also can't partition again the sd card from my mobile.
Try to format your sd card via cmd (windows).
Just a thought.

didn't work either..

Using an sdcard reader use the windows program called easeus partition master. If that doesn't work your only hope may be a Linux terminal. But make sure you use a different card reader as to rule out the phone as an issue.
Hiya mate, have a try with Heavy_Metal_Man suggestion with a partition manager, a good one I use is Mini Partition Manager, it has detected the 3 cards I have broke before :silly:
mount it to pc,
completely remove all partitions
and create 1 new partition across entire card,
reboot in to recovery when it tells you its created the partition.
and try it again
Hope this helps, if it did click " Thanks " on the posts you think helped!
ok guys.
thank you for your help.
i solved it...
i used MiniTool Partition Wizard Home Edition (with card reader) and saw the sd card and recreated all the needing staff so the sd card could be usable again.
what i did with CWM recovery is that i didn't replace totally the stock CWM,i just run the v5 something like virtually.and that created the problem.
thank you guys for your response!
cheers.
First of all, I think my first thread was in the wrong section so I decided to post it again HERE. Please lock and remove the old thread. http://forum.xda-developers.com/gal.../im-trouble-applying-update-external-t3023915
So, yeah. I can't apply update from external storage. It has no content. I tried formatting my SD Card and performed a factory reset. I can't flash anything from it. My baseband version is I8160XXMG2.
Actually, when I choose "apply update from external storage" there's some weird combination of letters, numbers, and symbols in it. I can't seem to remove it. Please help me ASAP. I want to install Cyanogenmod 10.2
Does File System format of SD Card need to be something like FAT32, NTFS or other for it to be detected in "apply update from external storage"? Right now it's Generic Hierarchical. Is there anyway for me to format it again via USB Cable? I don't have any card reader.
Anyone? Please help me...

If you can put SD cards in your computer you can reformat it from there. You might need an adapter if your computer doesn't take micro sd cards. My SD card came with an adapter (basically a piece of plastic to slide the small sd card in so it becomes bigger to fit in your computer).
I believe it needs to be FAT32, not sure if it would work with other file systems. But if it works for other purposes on your phone it should already be FAT32.
I'm not 100% sure about this so you might want to wait for a reply of someone who has more experience.
Hope it helps.
