on my old ipod 3rd gen 15gb with scroll wheel, it tries to boot but comes up with a folder with an exclamanation point. when i plug it into my PC, FireWire will acknoledge something attatched, but doesn't show up in itunes or My Computer. In the device manager, it shows up, but says that "this device cannot start" I can get it to re-boot (still doing the same thing), but cannot get it into restore mode.
