11/30   I have one of those tiny Sandisk keychain harddrives, and it shows
        it as being nearly full (~500 of 512megs), under OS X, where it
        also shows the drive as having no files on it. But when I plug the
        drive into my PC, it shows a .Trashes file which has all the
        files I've deleted off of it, ever. What is this .Trashes file and
        how can I delete it under OS X (I can delete it with Windows)?
        Thanks.
        \_ Uh, empty trash?
        \_ .Trashes is the trashcan created by OSX.  You can empty the trash
           or just remove it using command line.
