what worked for me
changing to a different USB port. this does seem to indicate that it is not necessarily the media, but possibly the data cable or communication port (obviously I moved the cable, too, even if i didn't change it). But i'd tried to format the drive 50 times, rebooting it between, FAT32, FAT, in XP with "tools" and with command line, with every concievable option. Then i changed the cable (while reading this thread) and *poof* the Invalid media disk unusable message did NOT recur, and the command line format worked. And tomtom just finished installing the "application" while I was typing this message (which it had been unable to do at LOTS of tries before ...). Apparently my last "lucky" format wrote lots of bad sectors ... maybe this old HP laptop has a bad USB port, or ....?
