Réponse à : « Does a new iPod hard drive need to be formatted? If so, how? »I am having this same problem -- I put a new HDD in the iPod and it isn't showing up in iTunes, on PC or on a Mac. I have charged it via FireWire (it's all charged up). I can get to the diagnostics screen, but it freezes if I choose anything. It will stay in disk mode and my Windows partition can see it just fine. I just don't know what to do to get iTunes to see it.
