The other day driving home from work my phone gave me an error saying it didn't support my SD card. I've had this in my phone since I got it 2 years ago. How can I fix it without formatting the SD card?
Poor contact of SD card can cause this, so:
Remove the SD card and checking the positioning or clean the contact area(copper)
Run CHKDSK on SD Card
Run CHKDSK to fix blank SD card error message by following the given steps:
Note: G is the drive letter assigned to SD Card
Before executing CHKDSK, make sure that the SD Card is connected to the computer or laptop and is detected by the machine. After the procedure completes, insert the memory card back to the phone to check if it is working fine.
What SD card are you using? Ive noticed an issue before that these galaxies are very choosy on SD cards from what i have experienced. Though its been in there for 2 years , software change could be part of the issue. Id clean the card , download to a computer.
