I have found that approx 250 mp3 files, in the range of E - Q (names) cannot be played on my device anymore! Using Vista 32-bit Win Explorer, they would not play from the device OR when I transferred them to my hard drive! No luck! These files are located in the internal memory of the Fuze. Also, I have notices that ALL files on my player have had their file dates changed to 5/30/2005 11:00PM. Thirdly, I attempted to delete the bad files but, it seems that when I re-boot the device, many of the corrupted files re-appear on the file listing in Win Explorer!!! Is my internal memory disinigrating?
