Well, not having one of those intuitive Macs ;) I'm at somewhat of a
disadvantage, but I'll try to assist with some basic debugging.
The first thing you have to do is determine if the file was corrupted in the
transfer. Choose one of the files that is causing a problem. If you do an
md5sum, crc32, or byte-by-byte compare between what's on the Firewire hard
drive to what's on the Jukebox HD, is it the same? If not, then the problem
is probably due to a file corruption during the transfer process or a drive
corruption problem in the Jukebox.
If the files are the same, then the problem is most likely due to the Archos
not being able to understand the file for some reason. If that's the case,
there are probably Mac programs which analyze MP3 files to verify that they
are in compliance with standards. I'd look for one of those programs and
use that against one of the problem files.
