I've had a Samsung Galaxy tablet for a few years now. A while back, I picked up a 32gb memory card. Recently, I've been running low on memory. I checked my apps, and the tablet no longer recognizes the card. In the settings where I would install the card, it reads "insert card". I tried a basic restart, no help. I took the card out, and put it into a card reader in a linux box I have. It recognized the card. IIRC there were 3 folders - Android, DCIM, and LOST.DIR. The only other thing I can think of trying is a factory reset, but I'm reluctant to wipe out all my apps/data/settings unless there's a good chance it's going to fix this. Any suggestions?
