So this is my second iPod (4G 40GB), a refurb that Apple replaced my original unit with back it November of '05. As of last night, this one is having the same exact problems as the one that it replaced, but the HDD checks out through the diagnostic menu. So I'm hoping worst case scenario, it's the Logic Board which is only like $50. Here's the problem I have now: At some point, my iBook stopped recognizing the iPod all together. So, as a last resort, I used Disk Utility to erase it. I didn't Zero Out Data which is what I think I should've done...? Now when I mount it (in Disk Mode BTW), iTunes opens up immediately yet the iPod doesn't show up in iTunes. Then, when I try to use the Updater, I get an error telling me that it can't unmount the drive because files are in use, I would assume by iTunes. I can't even unmount the thing manualy from the finder. Closing iTunes doesn't do the trick and I get the same message when trying to use Disk Utility on it now. I was going to try and Zero Out Data, but can't even do that now. Any tricks? Thanks in advance.
