550d won't boot w/ card; card renamed to EOS_DEVELOP ?
Created originally on Bitbucket by mattygbd
Background: Shot some footage yesterday using ML, was transferring it to my Mac with a USB card reader and not paying much attention. When it was done transferring, dialog popped up saying that the disk had been ejected improperly (although I never removed the drive). The card was somehow now renamed 'EOS_DEVELOP' instead of whatever it was before that, and it shows no files and appears completely blank.
The card is a Transcend 32GB class 6 formatted, ML'd and bootflagged on a Macintosh following the Vimeo tutorials from sawomedia.
Now of course putting the card in my camera means it won't boot. My camera does boot without a card inserted.
I need to re-install ML to the card and get my camera and card working by tonight when I have a shoot!
