Hello. I was just about to turn on the music syncing when it said something like, "This iPod is synced with another computer. Do you want to erase it and sync with this computer?" I've recently switched computers, so that's probably why it said that. Now, does that mean it's going to erase absolutely everything on it? I have movies on it that I didn't keep in iTunes for space reasons. But I don't have Movie sync turned on. The only actual sync that's going on is photos and calenders & contacts. So my question is... if I turn on the music sync... will it erase just the music, or everything? Is there a way to de-sync it from my iMac? I'm not sure I remember actually turning on the sync feature on anything on the iMac, but if I did it's probably for the photos.
