I have a 16 Gb SP Class 10 MicroSD card and it was used on a Lenovo phone for long. It still has information on it, and about 10 Gb free memory. Here is the interesting part - I can copy from it on my computer. I can copy files on it - BUT !!!! - after eject it from the computer or a phone, all the files that were copied on it - ARE NOT THERE ANYMORE! Only the ones that were left from the phone can be found on it. Secondly - the compter and other phones cannot format it. It just gives an error saying UNABLE to FORMAT.
WHAT THE HECK IS WRONG WITH THIS WEIRD CARD?
even after I delete something from it, that files appears back after putting back the card into USB
I formated with long format with this program https://www.sdcard.org/downloads/formatter_4/ and it says format succesful complete, and after refresh the disks, the card is again full with those files. LOL what is happening?

Hello,
My rom(iNsertCoin) has crashed today for an unknown reason, and entered nonstop bootloops.
I have tried to reflash the iNsertcoin zip but it didnt work for some reason, also it told me it cant mount the sd-ext (I am using ra-desire 2.0.0).
I have turned the phone off, and when I returned home I put my A-Data 16gb Class 10 Microsd (which was bought from newegg, so it cant be fake) in my card reader, and I started to partition the card like this: 1gb ext4, 300mb ext4, 100mb linux-swap, rest to fat32.
all of a sudden the program just crashed and from that point it tells me the card has 1gb unallocated space, in windows 7 it keeps asking me to format the card but it never succeeds, and it says the card uses raw file system.
I have tried chkdsk, and it told me its not available for raw filesystems.
I have also tried a number of programs, the HP partition tool, SDFormatter, nothing really helped.
Also, I tried using diskpart -> clean all command on the card but it keeps giving me weird error messages but usually it tells me its not ready, and it looks like the card is not responsive, although the pc recongized it.
I have tried doing this from a number of computers, another W7 computer and a XP computer. nothing worked.
I cant allocate space in gparted, and it tells me to create a partition table, and when I try that, the program just hangs.
Oh yeah, and I tried to put the microsd card into an adapter and put it in my dad's dslr and tried to format it, but there was an error.
Have I killed my microsd card? :/

try using androids built in sd card format tool. settigns, sd card storage, unmount sd card, then format. try flashing clockworkmod recovery and using there builtin format ooptions,, if still no go, u mayb have friemd your sd card. by the way, u sjould always use your fat32 as your 1st rive and never 2nd or 3rd. im quite sure u makes your pc read the drives in the order u created them.

Thanks, but I have already tried to format it from the phone, and then recovery. didnt work.
and i made my fat32 as my first drive i just listed it last..
well I have sent it to A-Data today, in taiwan, and I'm hoping I will get a replacement card soon.
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'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'm not sure if this is related to the 4.3 bug or not but I have the tmobile galaxy s4 and I can no longer modify anything on my external sd card. Everything still reads fine but it seems alot slower than before.
I tried using es file manager to delete/write , but it dosen't work. It will say deleted successfully but when i refresh, it reappears. When i try to create a new file it says "sorry, operation failed"
I also checked the permissions file and it says it has r/w access for external storage.
Is my card just dying or corrupted or what? How can I fix this?
I just want to be able to use it again.
I also tried formatting. When i do it on the phone it just freezes. When I do it on the pc, it says write protected.
I tried gparted as well but it hangs during detection.
This is the default micro sd card that came with the phone...

Remove your external microSD and plug it into a card reader and or the adapter which came
with the card then plug it into your computer.
Make an empty folder on desktop of computer and copy all files and folders from the microsd
card into the empty folder.
Format your external microsd using this windows utility and copy all the files/folders back onto
the card from your computer and replace it into your phone.
Here is the direct download link for this fat32 formatter which is a windows utility:

I having the same problem, the software cant help...
I have an non rooted, official Tab Pro 12.2 on 5.1.1. with an 64Gb sandisk Ultra SDXC micro usb card. I use the sd for movies on holidays. A few weeks ago i suddenly couldn't delete or write any files anymore. Not even format the card in the Tab, on Windows Xp, Windows 10, or even Linux Mint. In other tablets or phones i get the message that the card is empty, but can't be formatted. When i take a picture, the image is stored on the sd, so it isn't broken. I just can't remove it anymore.
I tried several programs for formatting sd cards, but i get the message that the card is write protected.
There is an folder named .android_secure and it can't be removed. I googled and found out that this is folder is created by app2sd, but i never used this app. Also i never moved apps to the sd card, so i don't understand how this folder is created. By the way, the date of the folder is 1-1-1970. Very strange.
It's very easy to buy a new sd card, but what if this happens again and ruin my next sd?
Has anyone had this problem and perhaps has a solution.

When the sdcard goes read-only the card detected a major fault with the card and a protection mechanism will switch the card to read-only mode so you can get data off (hopefully), unfortunately the card is toast there is no way to revert the read-only/write protect mode, Sandisk has lifetime / 10 year warranty on most sdcards so just contact their support and they will ask for the serial number on the back of the card (use a camera or magnifier glass to read it), do the rma form and send it to them and they will send back a better brand new card usually a good model, if you have valuable data on the card you can snap the card in-half (since it is read-only you can't erase it), just make sure to note it with support ..
I have been through two sandisk cards (both 64gb), one went poof dead, then the other did what yours is doing can't delete/write/format but you can see all the files - sandisk replaced the card twice no issues, the last card they send it working great no issues.

Thanks for your advice!
I mailed Sandisk and they will sent me a new micro sd card. They know about the problem with some of there micro sd cards, so there was no problem with that at all.
Worth a try.?
This has happened to me several times on different occasions.... typically after I have deleted all the extra and hidden files and folders my phone apparently likes putting on my SD cards. When I get that message, I will right click C: drive, select properties, go to Hardware tab, highlight the storage device, then run the disk check on the tools tab. 9 out of 10 times it will scan and fix errors on the disk... when it does not.. I redo the whole process.. . lather... rinse... repeat
