Thanks for the quick info. It would seem that on my Mac I cannot mount the drive in Thumb Drive mode. I checked out the link you posted. I had assumed it was those tiny Unix files building up. I always knew they were there. They appeared to get deleted when I would delete the MP3 that they were associated. Maybe they were not. I downloaded the software he posted to show hidden files. It only showed the few ._ Unix files that were with the MP3 files that I had on the unit. I couldn’t find any other hidden files to make up the 375MB or so of missing space.
I ended up doing the format which brought me back to about 950MB or what have you. I guess I just need to do that now and then. It took a long time for the space to become noticable. At least a few months.
Thanks for the help!
