I have a Verizon Galaxy S3 16gb with a 32gb micro sd card. For some inexplicable reason, I am losing data on the micro sd card. Folder names are being changed to start with the character "μ." For example, my_music was changed to μy_music (this does not happen on the device's internal memory). Is it a problem with the Micro SD card or something else such as the phone itself? Is there any way I can fix this?

Sorry if this is in the wrong forum. If it is, please point me to the correct one.

Try reformatting your card. Did you format it when you put it in the phone? Is it new or used?

If you're "legally" downloading music from your phone, sometimes the file names are in different languages, such as Russian depending on where the original mp3 you downloaded was from try checking if there is music in that file

Sounds like a corruption to the SDCard. I had a 64GB MicroSDXC card that did this all the time with my music files.

I have experienced the same with my 32gb Sandisk Micro SD card 10 class using in the Galaxy Tab 2. The SD card is genuine so I know that's not the issue.
However, I have found this to work for me.

1) Format the card on your PC or Mac, to NTFS file system.
2) Download Paragon NTFS / HFS apk app for your Android device
3) Without ANY NTFS app for the android, the android WILL NOT recognise the inserted SD card NTFS format as the android only recognises the FAT file system only
4) Put the Micro SD card into the device and restart the device (if the card icon shows in the notification bar, bottom right, ignore)
5) Goto and open on Android Paragon NTFS / HFS tool apk and check disk / format using the android app
6) Restart device again, with SD card inserted, leave card inserted and connect Android device to PC, the External Disk should now be available formatted to NTFS

The card should AUTO MOUNT via the Paragon NTFS app when the device is turned on

You can format the SD card to NTFS using the android app

I've tried every method possible to have the SD card in the FAT 32, but it just doesn't last, folder names change, files dissapear.

Thanks for reading

See the "exFat vs Fat32" part of my post here:

You could try formatting it to ext4, android will recognize it as it is an embedded linux system, however it won't be recognized in windows as microsoft only supports their file systems and no others.
