It's a long story, so here's the cheat sheet:
1- Girlfriends buys an iPod off of Ebay. It comes, it works, she hooks it up to her Mom's laptop. While it's syncing, the battery dies and it starts giving her the sad face iPod man. She puts it away for a few months until I agree to fix it.
2- I open it up, unplug and replug the hard drive, it works again. When we go to sync on her PC, it'll sync about 1000 songs and then it sounds like the hard drive gets "stuck". Click, whirr, click, whirr. It plays whatever is ON the iPod fine.
3- I sync it to my Powerbook no problem. Because my library>Her iPod size, it creates a playlist to sync with her iPod. This works fine. However, ANY change to the preferences instigates a "Can't find iPod" error.
4- Restored it on the PC and it gave one of those ?Folder warnings. Restored it on the Mac, syncs fine, but same problem with the preferences.
We did the business card+rubberband+hard drive trick. I'm confused as to what the problem is. We can sync it on the Mac, with the one playlist, but that's a little inconvienent. Any ideas?
