galaxy tab 2 not reading sd card
I've had a galaxy tab 10.1 for 3 months and I had placed an .sd memory card in it and I placed music and movies on it as well as photos shot by the camera. It was working fine till suddenly it is not read by the tab anymore and I get a message that it needs formatting. Placed the card in reader of the lap top and it wasn't read either and asked to be formatted.
When I try to format it from the tab it refuses and say card contains unrecognized system files.
Now I wanna know why that failure happened? And it is reliable to have data on the .sd card or does this failure occur constantly?
