I keep having the same issue with my Sansa Fuze +. I will download all my music into the mp3 player, and after charging it 5-10 times, it will out of nowhere corrupt all of my music files and playlists. The only solution I have at that point is to re-format the SanDisk 32gb MicroSD card and reconnect my Sansa Fuze + to Rhapsody and re-install everything. I’m getting to the point where I don’t want to charge up my Fuze + for fear that I will have to re-format and re-install all of my music.
I don’t know if I am running the latest firmware. I have Windows 8 on my computers and when I download the firmware, I get a message stating that the firmware updater isn’t compatible with my operating system. Also, I’m not doing anything on my computers that involves the USB ports or the Sansa Fuze +, so it isn’t a program in my system or something of that nature that is corrupting my files. I’m just tired of turning on my mp3 player and it scrolling through the music with the message “corrupt file” appearing before it moves onto the next file and does it again. I’m also irritated that the playlists will appear as “Unknown” when all the files become corrupt. Is anyone else having this issue, and is there a resolution for someone with a Windows 8 Operating System?
