Ok, I have done some research on this issue, and not sure if anyone knows exactly what is going on here. I have a few SD cards from various phones. When I have been using CWM I can only access a certain SD card. The others all say Error can't mount SD card; however, the phone uses the SD card just fine. Only CWM gives me a problem with this. Well, attempting an update on the ROM I'm using my SD card that worked before now does the same error. Any clue as to what is causing this? Any possible solutions other then buying a new SD card? Thanks!
