G6 real, Issues

For some reason my G6 will sometimes read that it's blank, even when it's not. the only way I can seem to fix it is formatting it.

Has this happened to anyone else?

Edit:It just happened again. This is really getting annoying, i just updated the card with about 7 homebrew games+apps and the card stops working. Please if anyone knows whats wrong, Please tell me!

Edit 2: this seems to happen sometimes when im done putting new software on, could my computer be doing something to mess it up?
