I just bought a new sansa clip today and started to upload mp3 to it. Then on a whim I decided to try copy those songs back to my computer and it didn’t work! What could be the problem?
How were you trying to transfer, and what mode is the clip in?
I’m trying to drag and drop the files. The mode is auto detect.
What you can try is put the device in MSC mode under Settings > USB mode, then plug to PC, format it to clean the device up in case your mp3 might cause some problem with it. Then try to reload again to see if it happens. If it does, I suggest you check your mp3 files.
