Dear all
I am almost desparate after having tried most possible ways to format a micro sdcard, but the files keep coming back. It's a sdxc 64gb sandisk in exfat. It used to sit in a Galaxy note 10.1 2014 (SM-P605), but I wanted to use it elsewhere too.
So I tried to format it with Windows10, xubuntu, osx el capitan, Nikon dslr, Android cm13, twrp recovery, custom stock Samsung Android 5.1.1 (just the original ROM that initially fornatted the card is gone), but the files keep coming back.
I am probably missing something or misunderstand something and you can probably help me.
Thanks
Full format in windows should wipe the lot .
I tried that and it resulted in an error. I formatted with sdformatter on mac, but after I re-mounted all files were back there.
In that case its not formatted .

Hi,
for a few days im not able to write anything to my sdcard (SanDisk 8GB). Im sure its not permission related (read only mode..). My computer (linux) can read flawlessly, just like my phone (Moto Milestone/TheFroyoMod 2.4c). But when i copy files to the sdcard and plug it back in, the new written data is lost. Same for my phone. I can take photos but the files cant be stored on the sdcard. I already tried to format the sdcard with GParted but it wont let me do ANY changes. Even if i format it to another FS, when i plug it back in, its still FAT 32 with all the data still on it. Windows wont let me format it at all.
Does anyone have a similar issue and manged to solve it?
ty!
Is it an old card, been used a lot? It may not be the case, but it sounds like nand that has run out of write cycles.
well ive been using it for 6 months now. Just regular usage.
It sounds like you've tried everything available to you. I'd recommend copying the contents of the SD card onto your PC for safe keeping and try to source another card.
Ok so I have a authentic Sandisk 32gb class 10 sd card. I t has randomly started to not mount in my phones. And when it does I will get errors copying data to it and such. I have formatted it in exfat and fat 32 using both the phone utility as well as windows to format it. I even did the full format that takes forever. It seems to mount in windows just fine every time. I can copy files to it with no issues. But both TWRP and CWM give error about can't mount external SD card as does my rom I cam currently running. Does this sound like a bad sd card or is it an issue with my phone? I am 8 days past my return policy on amazon currently and it just now is giving me issues. Please help me trouble shoot this guys. I don't want to attempt an RMA with sandisk if I can fix something phone wise. I flash a lot of roms and such but I HIGHLY doubt that has anything to do with it. I even reflashed my recovery and tried different versions with no luck!
Mods: if this will get more help in a different forum please feel free to move it for me
Ugh. Any help guys? I have still been messing around with it and the card seems to function perfect under windows and passes all scans and such but will either not mount in the phone or has errors doing other things while in the phone
Update: I did more formats and reflashing recovery and still no luck. I copied the rom to the 32gb card with zero issues on windows. Tried to flash it on phone and twrp gave errors. Copied same rom to an old 2gb card I have and it flashed perfect. Is it my phone or is it the card? Card works perfect in windows. 2gb card works perfect on both! Is it possible for something on my phone jacked up that would make it only work with the 2gb and not the 32gb card? Scans never show a single issue in windows!!!!!!!!!!

What happens if you try the 32 GB microSD card in another phone out of curiosity?
Use 64GB sd card(Fat32)to store photos and video, but it crushed once i plugged into the device. Photos not preview and video showing FILE CAN'T BE PLAYED. Is anyone experience this? I understand the KitKat is not writable on the SD card, but i'm not sure is storage not available as well. PLEASE HELP!!!!!!!!!
Try to reformat the card via your PC, fat32 and try again. If that doesn't work, try to reformat in EXfat

Try everything I have done, no luck. is this mean my SD card is not working or what. I know some people can use up to 128G.
P.S. SD card shows mounted to the device properly and working fine in my other device.

I'm not say that this is going to, or still is an issue, however, in MY OWN PERSONAL EXPERIENCE and from what i have read 6-10 months ago or more (maybe they have solved this issue by now i don't know) every time i formated an SD card Via PC it was horrible and the format destroyed the MicroSD card for use with any android device and then even my computer and they where all BRAND NEW. I think it has something to do with the formatting process of the SD cards and the phone because my 32GB cant be recognized anymore by any device but i can format it all day long on my PC and my androids will not see it... I even tried to format it BACK to what android uses to format the cards on ADB and NOTHING ever worked again. MY SUGGESTION IF YOUR USING IT FOR YOUR PHONE DON'T FORMAT YOUR CARD VIA PC. Flash memory is also has a write life. UNLIKE A HDD that you can erase and move files around constantly the more you erase and move files on your SD card the quicker you are going to see the integrity of your card degrade because FLASH Memory can not handle the constant moving and erasing over and over again. so if you want to ave the life of your flash memory and don't want it tos burn out because i guarantee it will, just be mindful of how many times you move and erase. just a tip. if im wrong someone correct me. good luck!
Try to reformat it on the tablet, not the PC. (Settings --> Storage --> Format MicroSD)

well, I was using my S4 GT-I9505. I flashed a custom marshmallow ROM and used my Sandisk 64 GBs SD card for adopted storage, formatted it into f2fs using my phone. it was working fine. a few months later, when I flashed kitkat official ROM using chainfire new tool, I bricked my device. Now I have two problems. First odin doesnt detect my phone in anyway, my pc says, device malfunctioned. and the main problem Im having, I cant use my SD card. Is there a way to use f2fs with windows or other device so I could transfer my important data to my pc and format it again? Help please.
Hi !
I guess any other android device can read the f2fs storage , as far as I know , Windows cannot unless you convert the data which obviously will wipe everything
Linux can read it though
Cheers !
