Had the TinyTV2 for less than 24 hours and the memory is already unrecognizable by Windows.

Its first use said it was corrupted, but Windows was able to "fix" it.   

I was able to remove a few of the stock videos and upload 4 newly converted videos (with no special characters in their names).   I left it plugged into my laptop to finish charging, but when I checked it the next morning, Windows can no longer recognize the built in SD card.  Tried it on 2 other Windows computers, same result.  So....now what?

EDIT:  I was able to get back into the drive.  After a few power on/off sets (of the TinyTV2), it got recognized by the Windows PC.   It might be required to be ON for it to be recognized after the first connection, since its Power off will disconnect it from the PC.
