[HELP] SD Card became Read Only !!! - Galaxy S III Q&A, Help & Troubleshooting

My 64GB SanDisk Ultra Class 10 card was running fine untill recently i flashed Omni ROM !! Then i was not feeling good with onmi and i returned back to Stock Rom..then the problems started to occur.I didn't notice at 1st.after when i connected to my pc to insert some files the files does not WRITE !! it shows that the files are being copied but when i refresh it stays the same old files which was previously there before....
What to DO ????
Can any one Help !!!

Use sd formatting tool on your pc, if still the same then buy a new card.

I have the same SD card, and sometimes when I flash a new rom I have to format because my phone is unable to read it. I always reformat it with SDFormatter V4.0, you can try it.
Do a "FULL (OverWrite)" format to be sure.

My S3 has killed at least 3sd cards of mine. Phone would start dismounting and remounting the SD card by itself, eventually the card would stop working. I've given up using a SD card in my phone

Mine has the same 32gb card I put in the day I got the phone, 2 years ago. Not had any problems at all, I avoid using the internal storage to reduce wear on the emmc chip.

I tried formatting it with windows but no Luck !! In windows it shows it formatted but when I insert it back into phone it stays the same .It returns back to its previous state... The thing is that my card shows that it is copying or deleting files but after a while everything just goes back to where it was ..I still have my old files unable to do any thing...so only Read Only ... :'(
Thats it I am never flashing a non stock based ROM ever !!

Plug ur phone to a computer if it detects ur sd card format using windows utility if it dont detect then u should use third-party software like acronis disk director....it's not free but it has worked for me in the past..good luck

I had this happen to me before on cm7. I reformatted it in windows (not quick format but full) and it seemed to work. But a few days later I got the SD damaged alert again. After playing this game about 3 times I decided to try SD formatter 3.0 to wipe the card and then I just booted into recovery and formatted it (seeing as it was wiped clean already) and it worked like a charm. SD formatter is free so I'd suggest giving it a try.
Good luck!

When you get this message its actually referring to your external sd(emmc).Don't format because It'll format your internal sd card which really sucks if you apps and music, etc.Try opening your ex-sd (emmc)on root explorer on your phone if you can.There's corrupt info on it I'm almost sure and wipe file that the has time stamps from like the year 1969.If you can't then use a microSD adapter and use your computer.Hope this helps.

Eh, I had this happen and formatted..it did my external sd card not the internal.
I've also never used CM7 or any other GB rom so i think it might have something to do with the SD card read ahead scripts that most ROMs are using nowadays.
Closing down thread as this is a duplicate thread. You already have a thread on this open.

[Q] MicroCD card can't be read

I have noname microSD card with capacity of 4gb and my S2 cant read it. If I put it on USB reader and stick it in my PC the card work normally but if the card is installed on the phone some error came on display about some kind of android process. I've formatted the card on my PC in FAT32 system but nothing happens. If I go to the storage the phone freezes for a moment and error pops up. I have another Kingston 2gb microSD card which is functioning properly. Can that be fixed or the only way out is buying a new microSD card with bigger capacity?
Check/scan for errors and fix in PC then FULL format (not quick) fat32 default allocation size.

Format card as FAT 32 in windows .
android.pocess.media is stopped"

SD Card blank or has unssuported filesystem

Hi guys,
so recently i screwd up my phone and needed a motorola factory cable to fix it. Now that i have it and up and running, i seem to have another problem.
My SD Card is not recognized in the phone. when i put it in my other phone, it works fine with all data there. Connected to my com and it reads it and what not. So i tried formating it again, and same problem.
Tried fastbooting my phone back twice to stock unrooted, and its the same. Tried factory reset, the same..
any idea how can i fix this? Or do i need to get my self a new SD Card T_T
thanks!!
Format the sdcard as fat32 partition from the PC. Use a program that can partition disks/ cards like MiniTool Partition Wizard
Hi! thanks for the reply, tried that, same thing
Hi, just to add..i tried a friends SD card in my phone, and im getting the same error. could it be due to h/w problem?

have you checked if 64 gb is supported from what i read most phones only support upto 32 gb, also forget the adapter try using it in another phone and see it could be the sd card is corrupt but make sure to check the phone is 64 gb supported sd card
Android 4.0+ supports up to 64gb SD.

yeah.. maybe 64gb is not supported..
Quite easy.Uninstall the SD CARD and install it again for several times. And it will be ok.
My english is bad....Or even worse than bad....

Weird files reappear every reboot

Ive just flashed official malaysia i9100g 4.1.2 taken from sammobile. After doing hard reset, format usb storage, I inserted a sandisk ultra 32gb class 10 then I got this weird files on /storage/extsdcard. I thought maybe its a virus ive formatted it using the phone. But after every reboot, its still there. And antutu seems to freeze whenever it reaches sdcard i/o test. It worked fine in 4.0.3. Is this a microsd malfunction or jellybean issue?

check in i9100G Android development forum instead. They have a Q&A there too
Update: looks like it happen when im using usb mass storage, mtp and ptp mode. I guess im gonna need a card reader after this. Then going to do vold.fstab mod later.

Seems to me that you will need a new microSD card.
But, try first with card reader on some PC. Format and then check card on PC.
You wrote you formated card in mobile phone? But those weird folders look to me like suddenly visible deleted folders. So after checking on PC format again in phone.
Then read again line #1 of this post. I'd like I'm wrong...
Ah... have you checked with another SD card?
It works fine with 16gb + vold.fstab mod. Im going to check this microsd in ubuntu before sending it for warranty.

[Q] Ext SD Card Issues

Wanted to see if anyone else is experiencing the same issue I am.
Was using my phone and my Samsung 64GB class 10 Micro Sdcard "ejected" although it was still in the phone. It had been working fine for a week. I manually ejected and placed it back in but it will not read. I get the "Scanning/Preparing SD card" Message but it always says unavailable. Thinking that my card crapped out on my, I put a brand new Kingston class 10 64 GB sd card but experiencing the same results. Oddly enough, I have an old Class 10 Transcend 8GB card that will read. I am running the stock OS-Unlocked Boot/Rooted/S-off. Only mods I have done are flashing the released HTC kernel that is R/W. (Dont know if I need to reflash the one that came with the phone), and flashed the SD card write fix posted in this thread :http://forum.xda-developers.com/showthread.php?t=2700310
Anyone know where I can get the stock ATT kernel that may have the correct drivers for ext sd? Any suggestions?
Copy what you have on the sdcard to computer and format fat32 then retry card in phone

Hey, thanks for the reply.
I have a SD card reader on my laptop and it recognized the card just fine but if I put the card in the phone and plug in the phone to computer via USB, it will NOT recognize/see the card.
Im pretty sure it is a software issue. Does anyone have access or a link to the stock ATT kernel/boot.img?? I'd like to troubleshoot but forgot to make a back up before I flashed the R/W kernel released here. Thanks.
Doesnt matter if the sdcard reader sees it fine in windows, your more than likely going from windows to android, try what I suggested. If the card is not formatted @fat32 it will not be read in phone...

Maybe I forgot to mention it but both cards are FAT32 formatted. Also, the samsung card was working just fine for a week before these issues started happening.
Im still searching for the stock att kernel.
Ok did you reformat and try them again?

Went to try and reformat them again and am getting some weird results.
If i plug them directly into the computer with an adapter and use SDFormat to format them, then the M8 will read the cards? However, it only reads half the amount of memory (30gb) and I do not have an option within SDFormat to change the size. Since M8 now reads the card, I went to format it within the storage settings and once that completes, it no longer recognizes the card...?? Not sure how that is possible unless the phone is reformatting the card to a format it does not recognize..?
Use sdcard reader on laptop format fat32,set it to default size...it varies on different cards, 4 kb 8kb 16kb etc...

Thanks for the continued assistance. I have done this but still only have Half of the advertised memory. When I first installed it out of the box, it worked and showed full memory (62gb). Also, the default windows formatting tool will render the card unreadable by the M8 so im using the program called SDFormatter. Seems like I'm running in circles so I guess I'll just deal with half the memory for now. At least it works.

Use above instructions to remove all partitions from sd card. Insert into phone it will prompt you about it being damaged and ask if you want to format it. Answer yes.
If you still continue to have issues, it is most likely a hardware issue.

Thank you guys for the help!
I tried using the above fix (disk part) but it didnt even recognize the device. L0ng story short. I was able to use BOOTICE to reformat my KINGSTON Sd card to 60 GB but my samsung only reads 30 (even though it is advertised as 64) I read that when you reformat some Samsung cards, there is a protected area that most generic formatting utilities can overwrite and render the card to half capacity. Not sure if that's the case but oh well. Got it the other card to work. Thanks so much guys! Now if I can figure out why the phone isn't turning on now.....
