Twice now, the phone has complained all of a sudden that the SD card can't be read. I tried plugging it into a computer, switching to hard disk mode and then back to charge only to get it to re-read the card, at which point it says the card has no filesystem.
In each case it had no problem reading the card after ejecting and reseating it (which of course means powering it down). Has anyone else had this?
unmount card in phone, format it in Android and try again...mine was having issues not seeing photos I've added to my card to formatted it and now it's fine
Or plug the card directly into your computer and format it as fat32. Worked fine for me!

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.

So it's possible I might just be dumb and screwed up, but I think I might have reformatted something that I didn't mean to reformat.
I wanted to wipe my SD card because I found that there were random pics appearing in my gallery of people I've never seen before in my life (got the phone second hand but popped the SD card in that I used with my old Fascinate). Opening up My Computer, there were two different removable discs that were the SD card inside my phone and what I now presume to be internal storage. I backed up everything I wanted and wiped both the SD card and the other storage device via my laptop.
Here is the problem. Whenever I boot the phone up, there is a notification that says my SD card is either blank or not in a compatible format... It asks if I want to format it, I click OK, and everything seems fine... Until I have to reboot the phone and it does the same thing all over again. This is getting to be an annoyance because I don't want to keep deleting everything on my SD card whenever I reboot my phone.
Can anybody help me fix this?
Okay I definitely did something to the internal storage. I tried taking my SD card out and rebooting it and I am still getting the blank SD card notification. It won't let me format it. What do I do?
Try connecting the sdcard to your computer through a usb adapter, or any alternative to using the phone's USB-mount. Format it with FAT32. Put it back in your phone and see if it works. If not, you might have a corrupt sdcard. Try a different one if available.
What directory were the pictures appearing in? It's possible they were cached from the browser or some social app.
I tried to format my sd cards tonight via computer format option. However my computer shut down in the middle of the process and now I can't see my sd cards anymore. I can't mount it at all. When I go into the recovery to wipe it, twrp says failed.
Does this mean it's completely dead?
solved it.
googled and found this thread http://forum.xda-developers.com/showthread.php?t=1806059 for my internal sd card
and for my external, i used a card reader, plugged to pc, and reformat it.
also checked both cards for errors.
whew. i am never gonna reformat my cards again. ever.
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!
for some reason yesterday my phone won't recognize the sd card. i know many people will as if i've reformatted the card. the answer is no. earlier in the day i was able to access the photos i had stored on the sd card and everything was fine. lastnight i was deleting some pictures on the internal memory and the folder that have my external memory pics had a "broken" image icon. i pulled the battery and sd, reinserted and none of the sd pics were available. i went into the menu and the phone says to mount sd/insert card (sd card is already inserted). i inserted the sd into an adapter and connected to my pc and the pc won't recognize the sd. i even inserted a different sd into my phone and the phone still didn't recognize. i haven't dropped my phone or exposed it to any moisture. the phone suddenly won't mount the card. i'm thinking the sd tray in the phone is glitched but it's so sudden considering i take really good care of the phone. the phone wasn't plugged in when this happened. any ideas on a resolution? thank you in advance.
