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!

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.
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!
Ok. Here is the scenario. Was on stock rooted LCJ. SD card working perfectly there. I flash to MIUI after doing a totally clean wipe and I'm able to access the SD card via the rom and PC when I sync. I go into recovery and do a full wipe and then flash CM10 with gapps. CM10 loads up okay but i notice that i have a notification that the SD card is broken and I should try formatting it. I attempt to sync the phone to the pc via USB cable but only the internal storage will mount.
I go into recovery and confirm that TWRP can still see the contents of the SD card. Having confirmed that TWRP can see the SD card I do another full wipe and then restore my stock rooted LJC. However, after restoring LJC the SD card issue persist. The phone does an error check but it doesn't fix the issue. It recommends that I format the SD card which I don't want to do and don't know if it will work. I attempt to sync the phone to the PC with the USB cable (which has always worked) but only internal will mount. Go into recovery and the SD card's contents are still showing up.
Also, I have a Kingston Media reader which I pop the SD card into and connect to the PC. Even using this media reader the SD card is still not being seen and the PC says the card should be formatted. Basically the only damn thing that recognizes stuff on the SD card is TWRP.
Anyone have any good advice on this topic? BTW...I have a class 10 64GB sd card. As mentioned above I never ever had a problem with this thing. Have always mounted it to the PC w/o a problem and has always appeared on every rom I have ever tried until trying CM10 today.
41 views and not one person has any input? guess i'm going to have to format the card and hope that works. really sucks balls. wish i at least knew for sure what caused this problem.
had the exact same issue. I had just purchased a sandisk 64 gig the week before and when it happened I had a hard time believing it was the card that went bad. I had no luck recovering anything off of the card but did format it and it has worked fine since.

Click to expand...
Click to collapse
its not the card...............its the formatting of the card. it has to be formatted fat32 for it to be recognized in cm10. stock format is exFAT
I had the same issue with my SanDisk 64 GB drive. I went back to Synergy and the card is recognized in that ROM. I can't get CWM or TWRP to recognize the card though. I get an error whenever I try to access the card from recovery. It sucks that I have to put anything I want to flash on internal memory
Hello,
I just got a 64 gb micro sd and just been experiencing issues since. I have formatted it to Fat32. It would randomly not show up when I plug in my phone, it does not show under it.
When I transfer music...they break? Will say something like so and so cannot be played, format is not supported or file does not exist. When I look at my musics on the computer, i cannot delete because it says i need written permission.
I am at lost for word at the moment because it is the second one I got...all having the same issue. When I format to exFat it does not even get mounted.
Backup your SD Card to your PC. Use the phone to Format, then put all your files back onto the Card.
I have already done that, it doesn't work...wouldn't mount
I bought a G7 Play during Thanksgiving sales at Wal-Mart. It's been running fine until today, when I rebooted.
It's stock. I haven't unlocked the bootloader or rooted it.
I have a 64 GB PNY Elite SD card configured to be portable storage.
Today, when I rebooted, I got a notification "SD card issue. Tap to fix." When I tapped, it wanted to know whether I wanted to use the SD card as adoptable or portable storage, and wanted me to reformat the card regardless of which option I chose.
I turned the phone off and removed the SD card, replacing it with a 2 GB Samsung card. That one functions as expected.
Has anyone else seen this behavior, and is there anything to be done to fix it, or should I just contact Lenovo?
Thanks!
Try using another phone with this SD Card. If it works then your phone is having incompatibility with the card. Didn't work? Your SD Card data has probably got corrupted. If you can plug it on computer with an adapter check if it shows RAW in disk management. If it does try formatting with windows usual format procedure. If that shows an error your last resort would be using diskpart. use list disk, then select the disk which is your sd card, then type clean, then create partition primary, then format. That didn't work too? Then it's a hardware issue and what you got there is part of e-waste now.
