I've had my droid x for about a week now and after I downloaded an app, which I found out was too big to run on the droid itself but would need to run on the SD card, the SD card will not read at all. I've tried formating it on the phone (there is no option to unmount, just to format and it doesn't work) and I've tried to format on my computer using severl micro SD card readers. When I try to format it says that the card is write protected. I've made sure that the reader isn't locked. I think it is an error with my card in specific because my brothers works fine when I tried putting it in mine. Is there anyway to fix this or will I have to get a new card? I'll be going to the Verizon store today if I cannot resolve this issue.
