This has been reported on Fedora Core 6 to me as well... iPods and
problems using parted.

From what you have provided, there appears to be a single FAT32
partition containing all of the data.  I'm not sure how Apple partitions
the disk that way, but they are probably not using a standard DOS disk
label, which would be my guess as to why you get the unrecognized
disklabel error when doing a 'parted print'.

I don't have an iPod and I don't know how to fix this issue without an
iPod.  If someone can provide specifications as to the disk layout in an
iPod, that would also be acceptable.
