I have had my desire about 3 months, the 4gb sd card that came with the phone started to show "damaged sd card" after a few weeks so I replaced it with a new sandisk 8gb card.
Now this 8gb card is doing the same thing.
The card mounts fine in windows but after I transfer files to the card or delete unwanted files via the pc, the phone shows "preparing sd card"for a long time then decides it's damaged.
The only way to fix it seems to be to format, but the problem happens again next time I transfer files to the card.
Originally I assumed it was the card but it seems unlikely that two cards would be faulty.
Has anyone had a similar problem or know a cause or fix for it?

Just one question - when you disconnect your phone from your PC, are you remounting the SD card on the phone first?
I've never had a problem with my SD cards, but I always ensure that I remount on the phone before I disconnect.
Regards,
Dave
I normally either unmount in windows or on the phone, thinking about it on the last disconnect I just shut down the pc then changed to charge only on the phone.
Maybe this is causing the problem?

when i done transfering files to the card, i switch to "charge only" mode on the phone, before i disconnect the phone from my pc.
if you don't do this, you will have to use "Safely remove hardware" on your pc before disconnecting, or you will end up with a corrupted sd card.

Hi all,
I just got a new Sandisk 1GB Mini SD for my Wizard. I put it in my phone and it was recognized immediately. I copied a few files across (my TomTom install and a few maps) and then finished the install. I had to soft-reboot to get TomTom to work - but after rebooting my card doesn't work. When the phone starts up it asks if I want to format the card. I tap yes and it goes away - but doesn't really do anything.
I have taken the Mini SD out of my phone and put it into the card reader that's in my laptop. Windows recognizes that it is a SD card and also prompts to format it - but when I try to format it as FAT or FAT32 it says it can't complete. I have tried doing it through DOS too, but it comes back as saying that there is a bad Track 0 and the card is unusable.
I'm struggling to believe that the card is now poked after just copying some files onto it. I'm hoping that it's just something to do with the file system that has dies somehow. Does anyone know how to reformat the card (either through my phone or Win XP) or how can I resurrect this sucker?
Thanks in advance!
try pocket mechanics
thanks rudegear. I tried pocket mechanics, but it doesn't even recognise the card. I believe that pocket mech will only work if my phone can see the card first. this isn't even happening. the phone obviously knows that there is a card in it, as it says that the expansion slot is in use, but it can't read the card at all. any other ideas?
sounds like you have a fake card. 128mb cards formated to show 1gb, you copy more than 128 they corrupt. this happened to me
okay. I've given up on this card and have sent it back. no more trying to ressurect the dead for me!
has the new card solved the prob? The problem Iam having is almost identical to yours. I purchased a 2gig mini sd card (bn) for my atom. When inserted into my laptop's integrated sd reader, it would recognise a card has been inserted but would not open the card (but the Atom recognised the card).
Thinking I have bought a faulty card, I sent it back to manufacturer. The seller tested and concluded there is nothing wrong with the card but sent me a new one.
I had the same trouble with the new card. Convinced the card was not faulty, I purchased a new card reader.
The firt day i connected the card into the reader. things were SMOOTHE! I was lovn life. The card was read instantaniously and i proceeded to fill the card with a hole heap of goodies (including tomtom).
I used up approx 100mb of stuff that day and ejected the card from reader and inserted in my atom. Data was read with no trouble on pda and pc.
I inserted the sd card back into card reader the following day and now it seems the data originally put on from the first 'contact' is now locked. I cannot delete nor add anything else to the card. Oh and before anyone asks: yes, the lock was and is in the UNLOCK position (i dont even use the lock).
So my next move now is to exchange my card reader with a simpler/single slot. I read somewhere that cardreaders/devices sometimes lock data (dont know how true it is but got no choice).
in summery:
buying an external card reader solved the initial issue of recognizing/reading sd card but created another problem of LOCKING the sd card.
Is anyone else having issues with large sd cards?
I solve the problem by inserting card to Digital Camera that use SD card.
it formatted without error.
Card Reader and other phones does not format it. I think because of file system.
hmm... I will try that. will keep you all posted.
I managed to get CyanogenMod 7 RC2 up and running. I noticed that I had a lot of junk on my SD card so I thought that I could back it up and then wipe it because most/all of the useful stuff was on the internal memory of the DHD. But, for some reason, my phone is telling me that my SD card is damaged.
I don't think that there is anything wrong with the SD card because I just did a copy/paste thing to back it up. Also, I've put in another SD card and it also says that it's damaged. Any help would be greatly appreciated!
Run fix_permissions and reboot

Thanks for the reply, but I don't think I can do that. I can't put that on my SD card because there if I try to connect it with the computer, I can't mount the SD card or turn on the usb sharing thing. I'll be able to reformat the SD card soon because I'm borrowing a friend's micro sd card to sd card converter.
I tried Fix Permissions by going into recovery and advanced options, but that didn't work =/
Also, I remember now that I uninstalled "Goldcard Helper" because it said it was downloaded to my SD card so I thought that I could uninstall it and be able to clean up my SD card completely. Maybe that had some effect on this?
Got my friend's converter so now I can plug the micro SD directly into my computer. Oddly enough, it said I had to format it before I could use it which is essentially what my phone was telling me to do too.
I'll wipe it then see if it works
Perfect! I think it is working completely now! One last question of what I should do now that it's working. Can I plug it in, restore a few pictures I had, and just let Android take over from there? It's completely blank on the SD card so will Android know what to do with it?
Hi All
I am hoping someone on this forum can help me before I rip my hair out (whats left of it).
I have recently got a HTC Desire and purchased a new 32GB Micro SD card. The SD card is fine and recognised when I first put it in, format it and factory reset the phone.
Boots up fine, recognises the SD fine and all apps work.
HOWEVER, when I plug my phone into the Mac I mount the SD card as a disk drive, Mac recognises it fine then I sync my ITunes music to it (about 8GB worth) then eject the drive from the Mac and remount the drive to the phone.
About 30 - 60 seconds after remounting to the phone I get an error message advising that the SD card is mounted as read-only. I try to unmount and remount again and it does the same.
The SD card basically renders itself useless.
I then take the Micro SD card out of the phone and put into the SD card adaptor for the Mac and run a disk varification on the card, the Mac itself cannot even fix it.
The ONLY way I can see to sort this is to reformat the Micro SD back to FAT32 and put it back into the phone, format and factory reset.
Again this ONLY happens at the point of syncing etc from the Mac.
Now before everyone starts to blame the Mac, after doing some Googling, it seems this also happens on Windows machine.
How do I stop this as its becoming a massive annoyance.

Okay so last night, I was just multitasking on my phone and all of a sudden, I get that dreaded microSD icon on my notifications bar. It says, "SD card damaged. You may have to reformat it." I have gotten this in the past and usually a soft reset fixes it (with the oem sd card). I did that, and it was still there.
I tried to connect it to my computer to transfer everything saved, but the sd card won't even mount, so my computer doesn't even see anything on the card! I even tried putting the card in the external USB card reader that came with the card and I can't access it.
I tried using Root Explorer, Settings, and Astro to access the microSd card and it won't let me since it is not mounted.
I am using CM7 RC4 with Lexar 32gb Class 10 card.
Any ideas? I really don't want to lose all my stuff on my SD card, but if I guess if there isn't any fixes, I don't really have a choice.
Try unmount the card place in a like SD adpater and plug in the computer See if it reads it.

Click to expand...
Click to collapse
Well it seems the card is already unmounted permanently at the moment. When I try to put it in the card reader, my PC won't even read the stuff on it. I mean it will show that a external device is connected but when I click on it, it just does nothing.
This happened to me and it scared the hell out of me. All I did was reboot and it was fixed.

Yeah, I think my card was f'd ..ended up just reformatting it ..lost everything. But it works now lol.
I'm having some strange issues with my S3 and micro SD cards. I noticed any attempt to access one of the folders will force crash any app that tries.
Then I did a nandroid backup from TWRP recovery and when I rebooted the phone, it claimed that the card was empty or damaged.
So I connected the card to my computer to backup everything that was there. Windows did say it needed to be scanned for errors but it didn't find any errors. It was formatted as exFat so I could put larger than 4 GB files on it.
When I put it back in my S3 it wasn't detected at all. No error messages, it was just as if I hadn't put any card in. Under Storage settings, under mount external SD card it just says to insert a card.
What I've found since then is in order to get the S3 to recognize that there is a card I need to do a full format (either FAT32 or exFAT) on my computer. If I do a quick format, it still won't be recognized. I need to do a full format.
But then, if I unmount and connect to my computer, then eject from my computer and put it back in my S3 it isn't detected again and I have to do a full format again.
I thought maybe the card had become defective, but I'm seeing the exact same behaviour now with a different card. The first one I was using was a class 10 32 GB lexar card. The second one is a class 10 16 GB Adata card. Both do the same thing. After a full format on my computer, they are detected on the phone but after unmounting, mounting on my computer, not doing anything except ejecting it, they stop being detected by the S3.
I've even tried re-formatting the card in the phone but that doesn't change anything.
Anyone know what's going on here? Is the phone defective? I don't want to send the phone in for warranty repair except as a last resort as I suspect that would mean several weeks without a phone.
Thanks!
