In August, I bought a 128GB PNY microSD card. It lasted almost two months, and then the tablet started acting funny. It would randomly unmount the card, it couldn't find my music files, and apps I had moved to the card would just disappear. I assumed the card was broken, so I eventually replaced it with a 128GB Samsung card. It's worked fine until the other day, when it started exhibiting the exact same behavior. I haven't been able to fix it.
I've tried formatting them both, but nothing seems to work. Windows can see the cards and the contents, but it's not able to format either card - it reads them both as write-protected, even though they're not. The only thing I can think that might cause it besides my tablet is Link2SD. I use this to move the large app data to the card since I only have 16GB of regular space. Could this be causing it? I'm at a loss, and I can't keep buying new cards. Any help would be greatly appreciated!
