Help sdcard unmounts itself

[chknhwk]

So I looked and searched but I can't seem to find anybody else having this problem. My sdcard randomly unmounts itself and the only way to get it to remount is reboot the phone and sometimes physically eject the card.
I am currently backing up the data on it so that I can wipe and format it using the phone software. If that doesn't work I am going to do a factory reset and reformat the card.
Any thoughts on what could be causing this? I am unrooted.

Cross your fingers - I backed up the card then wiped and formatted it with the phone. After that I hooked it up with HTC Sync and put my files back on it. So far my camera gallery isn't showing up but I'm not sweating it because I know I backed it up. Hopefully my card will stay mounted now. :thumbup:
