I’ve never had problems with my sansa clip 2gb until recently when it will no longer be recognized at all by my computer when i plug it in. I’ve tried the firmware updater, however I can’t use it because my mp3 player isn’t even recognized by the computer. I have the correct windows and and also windows media player. Like I said, I’ve never had problems before. I’m running out of options, and I’d like to know exactly what formatting would do because I dont want to delete all my songs if it’s not necessary. Thank you for your help because I’m in desperate need of it!
