So I bought SanDisk 32GB Mobile Ultra Micro SD (SDHC) Card - Class 10 UHS-1 and everything was working fine until 3-4 days ago.
Now whenever I remove it (unmounting it manually first) and put it back in, the phone doesn't detect it. If I restart with the card in, it detects it. Also the card unmounts very often while in the phone, especially after waking it up from sleep.
I tried 2 other cards (8GB and 16GB) - no problem - I put them in and the phone instantly detects them.
The 32GB card is working just fine on my computer and on Galaxy S I9000. I even ran ChkFlsh.exe on in from my PC = no problem.
Then I restored a backup through CWM Recovery when everything was working fine = still doesn't detect it after remove/insert again. Only after a restart it will detect it. I tried different kernels too. It even shows Damaged SD Card now and then.
What is wrong?
Try to format ur sd card to fat32 format...... CWM not work well with exfat......
Sandisk cards have lifetime warranty
Found this thread - SD Card Unexpectedly Removed
It turns out there is some problem with some SanDisk cards so I'm returning mine and getting another one (Adata).

I am using T-mobile Touch Pro 2.
I am quite satisfied with this device except for one problem.
Sometimes (once a day or every other day?) when I turn the device on, the micro sd card is not detectable. The card is in the slot, but the device just cannot find it. (It shows like there is no sd card!)
When I reboot the device or take the micro sd card off and insert again, the device recognize it which makes me very annoyed.
Anyone who has the same problem and the solution?
Many thanks in advance.
FYI, I am using Transcend 8GB micro sd card (class 6.)
The only time I have something like this issue is when I connect the phone to the PC as an external drive, which is by design. Unplugging the phone sets it right again.
Change your MicroSD to SanDisk and you wont have any problems. I have a class 2 16GB and I dont have any problems. If you're worry about the performance, it's pretty fast. using the phone as removable drive it writes at just under 4mb/s, using a usb adapter and the write speed sustains at 8-10mb/s which out performs minimum class 6 standard. All the test was done on a 16gb class 2 with 10gb of badly fragmented files already on the card and writing another 5.5GB into the card. I havent tested read speed but it's faster than write speed.

I had the same problem when i first got my sprint pro 2. All you have to do to fix is... using any card reader, copy all the files on your micro sd card to a new folder on your computer. then format the card to fat32. once formatted copy all of your files back onto the card. pop it back in and you should be good to go.. after doing this to mine, my 16g card hasn't disappeared once.

Thanks a lot!
I will do what you said right away. Hope it will solve the problem
So far i have been using the old sd card that came with my Arc S. Its been working fine but ive ran out of memory. So i bought a new 32gb MicroSD HC card. Its class 4. This one to be specific -
SanDisk 32GB Micro SD HC Memory Card
SDSDQM-032G-B35
I inserted my new sd (empty) into the phone. When the phone started, there was a Sh*t ton of lag. I basically couldnt do anything. You could say the sd card froze my phone. Is this normal ? keep in mind, the sd card was empty. I got scared and immediately removed the SD card. I put in my old sd card, it still lagged but i waited for about 30 minutes and it was just fine. Its been fine ever since. I have copied all the contents of my old sd card onto my pc and then onto my New SD card. I'm confused on whether to put it in or not. Will it harm my device? As far as i know, Arc S supports 32GB. My phone isnt rooted or anything. Just official Sony ICS if that helps in any way.
Thanks for the help guys.

Your phone stucked/froze after insertion of new empty microsd since your phone is basically looking for the previously installed applications and games when it started.
By copying all the contents of your old microsd to your new microsd before inserting this to your phone will prevent the freezing upon startup, although minor lagging will be encountered a few hours or so while some syncing is done.. I did it your way when I upgraded from 16GB Class 4 to 32GB Class 6 (although not all the files, i left out the videos/mp3s/dcim since i can copied them back later) and encountered no problem. So go on, insert your 32GB microsd already:laugh:
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!
My SD card is always corrupted. I tried using different SD cards even i bought a brand new SD card and it is still giving me issues . I did a factory reset and still does the same. Anyone else with the same issue?
What's the capacity and speed of your SD card? How are you formatting the SD card? Do you use it preformatted or format using the phone? The reason I'm asking is it seems to me that Sony has set a too low timeout values for formatting and mounting the SD card. So if your card is very big or not fast enough, the phone would timeout too early when formatting and/or mounting the SD card on boot, thus causing it to be detected as corrupted. At least that is how it seems on my phone.
perhaps have reset your phone from previous backup ? if this is the problem already happened to me ,
They are both high speed cards 10 cards Toshiba and Samsung to be more specific. When i format them they seem to kinda work at the beginning i even managed to copy a video file but after a phone restart it gets corrupted .
MM updated through xperia companion here, seems to be working normally with the old microsd card
Hi Team,
I also have the same issue here, whenever I move applications to SD card (Samsung Class 10), the application stops working and I have to
reboot the phone to have it running again. Though it happens only... when phone is from Doze mode, turned on the screen with power button, and after turning on mobile data and run the app like COC or Viber it crashes. Now this happens only, if my application is in SD, if it's on the phone it's working fine.
Hello everyone.
I also have this problem. I have a Sandisk ultra (red and grey) 32gb class 10 sd card, and my M5 on 6.0 cannot format it at all, first it says it's corrupted and I have to fix it, then the format screen is stuck on 20% and after a while it says the card cannot be formatted. The card isn't counterfeit, and it worked flawlessly in my m4. It was replaced under warranty because I presumed it became faulty, and I still have the same problem. There is no problem with it on my PC. Also the phone freezes when the card is removed and I have to turn it off with a paperclip on the small "off" button.
You have sd card restrictions on 6.0, so you can use it for media, can't move apps... I've got Transcend sd card class 10, no problem at all.
I know about the SD card restrictions but my card was working fine in 5.1 for storing photos and videos taken by the camera applications . Now i have tested even more cards and they all have the same behavior. Even with an 4GB and 8 GB Toshiba cards and an old 2GB transcend card.
tonev, how are you formatting the card?
On the phone it self. Also tried to format it on my laptop , Same result. Sometimes it works fine and after i restart my phone it gets corrupted again
any news or fix here? seems we're stuck with this sd behavior? can't really move apps to sd card?

Is it correct to assume that you restart the phone only using the default power menu and not using any third party interface?
Another thing, it is not advisable to format the SD card using Window's Format function. It is possible to damage the SD card this way. The safest way to format an SD card in Windows is by downloading and using the SDFormatter utility. I don't know if formatting you card in Windows is what has caused your SD card to be corrupted, but it is something to be considered.
Yes i do restart the phone only by using the default power button. menu. And none of my cards are corrupted because they work fine on other devices. As i said before a brand new never used genuine samsung SD card does not work on the phone.
I have a 128 gb Sandisk Extreme micro sd card which I used for nearly 3 months. Yesterday it stopped working all of a sudden and neither my HTC 10 nor my PC recognizes the sd card anymore. I cannot see what's inside the card and cannot format it.
Is there a way to recover the sd card?
Any help would be appreciated
