Ipod 3rd generation won't mount unless in disk mode?

When it's in regular mode, the ipod won't mount (after like 10 minutes the computer recognizes it as "Corrupted ipod" and tells me it needs to be restored) and when I try to restore it, it either freezes my ipod or error code 14something comes up.

I put it into disk mode and plugged it in and it came up in like 3 seconds, with the right name and everything. I know you have to restore it, and I did. I clicked restore and it "Restored" the ipod and said "Wait while your ipod is reset and shows up in the screen" or something like that, and it reset my ipod, but it did the same thing it has been doing and didn't show up.

It charges fine, so you would think I'd be able to play my songs, but no. It won't play the songs at all, it recognizes that they are all there, but when I press play, it just sits there at 0 minutes and 0 seconds...

It is broken forever? :(
