Computer isn't recognizing my iPod

[adri1456]

I have a 10gb 3rd gen iPod, and lately, my computer connects my iPod to it (there's the Safely remove hardware icon in the notification area) but then it won't display the ipod in my computer or iTunes. Or when that didn't work, then when I disconnect it, a few seconds later, the iPod will have a "don't disconnect" message on it, like it was connected.

I just have to backup the songs before I reformat it, but can I do that safely? (restore the ipod firmware and ensure communication between it and the computer)
