We had an accidental short between the positive and negative outputs of our power supply that was powering one of our Fins. After replacing the power supply we could not get the Fin to boot. When booting the Fin in MSD mode it enumerates as a 32.1 MB block storage device rather than the expected 8 GB. My best guess is the MMC was interrupted during a sensitive operation. Has anyone run into this before, and have you found a way to recover from this state?
