I was wondering if anyone else has had this problem. I'm currently running Sapphire 0.6.2, and quite a few times now when I've tried to make a backup just before making a change, I get a 'exited with status 31' error, which is pointing to a corrupt sd card. A format usually fixes this, but the risk is that if I ever run into something where I need to access the SD Card form recovery and can't then I won't be able to restore a previous backup. Possible defective SD card or maybe something else? Any thoughts are appreciated, thanks.
