Filebox no longer sees the 64G SD card when I put it back in & restart the phone.

Checking the SD card on a card reader on an XP machine, the original contents of the SD card are apparently OK.

I think I will spend the afternoon backing up the SD card before working on getting the N900 to see it again, in case it may corrupt the SD card. The entire population of the planet Crouton was digitized & downloaded to my SD card before the planet was destroyed, & I would hate for the CSSU team who work so hard to make the N900 awesome to inadvertently commit genocide. It wouldn't be fair.
