Hi,
I have a 128GB Sandisk SD Card. and had it setup as internal storage.
This morning. I noticed that some of my apps installed in my SD card are missing. so I checked my SD card from my file explorer. turns out it doesn't see the SD card. So I restarted my phone and my SD card still did not get recognized.
Then I removed the SD card and inserted it after restarting. then a message of
Code:
'This device doesn't recognize this Sandisk SD card.'.
When formatting it. I got the
Code:
'command '20 volume partition disk:179,64 public failed with 400 XX Command failed'
Tried putting the SD via OTG and formatting it via that way and I am still getting an error for it.
I did a few research about the error, and said that I can try and format it via PC. then I did go to my PC to format it. On my computer it shows 2 partitions
Tried doing the normal formatting for both of it. One shows 16mb and the other as 119GB. but both doesn't continue and I am having this message
Tried looking at it via Disk Management and can only perform this
And getting this error when trying to do so
Also tried doing it via diskpart and still getting this.
I need help on this. I feel that there is something I(We) can do to salvage this SD card. Any help would be appreciated.
Also, I haven't tinkered on my phone so it's not rooted/flashed yet (hoping that i wont be needing to do this). And the SD Card is authentic as I bought it from a reliable store

I'm using MIUI-1.12.9 with APPS2SD after preparing a 512MB partition for the apps on my 8GB Class2 MicroSD Card. The remaining section I used to store files for flashing, music, data, etc.
Now all of a sudden, my phone gives me 'You may remove the SD Card' error. It shows the MicroSD Card as unavailable and even when I connect vias USB, the computer cannot detect it. I tried connecting the card separately to the computer using an adapter, but no luck. However, it still reads the EXT3 partition where all the apps are stored as all the apps are still available to me.
Any ideas on what could be wrong and how to resolve this? I want to backup all my apps first but I can't do that with out Android recognizing the card.

This morning I got a notification that it was safe to remove my SD Card. I thought that was random and funny so I went into Solid Explorer to see and it said that my SD Card was empty. I checked in the Storage option in the Settings menu, and it didn't pick up the card. It only said "Mount SD Card, Insert SD Card." I removed and inserted the card a few times with no luck. After restarting, the phone told me the SD Card was Blank. I clicked on that notification and it prompted me to format the card. I tried to format it but it didn't work. I just kept telling me the card was blank and I'd need to reformat it. Finally, after plugging the phone into my computer, it's not even recognized as a card on the phone. Can someone help me please? Is this a hardware issue? Did the card reader on my S3 just crap out or is it something I can fix with some software fix?
Thanks in advance.

I could be the card that has failed. Do you have a card reader that you can use to mount the card on a PC (without the phone)? Do you have another card to try in the phone. It is one or the other that has failed but you will have to try out the combinations to see which has failed. I have seen cheap cards fail and become unrecognizable. I think that is more likely than the phone card slot failing.

Thanks for the reply. I'm starting to suspect/hope it's something wrong with the card itself as opposed to the slot. Unfortunately I don't have my old card or another reader around to test (I'm stuck at work). I may try to skip out to buy a new card and see if that does the trick.
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!
I formatted my S9+ and kept getting an error stating the SD card was reado nly. I tried everything possible to format the SD card on the phone & the PC. But, nothing works. Anybody has a fix for this?
Try to remount it and if it was used con ect it to the last device that it was read-write with and try disabling write protection
