OK, that was interesting. Here is what happened when I plugged it in:

Jul  3 20:38:45 localhost kernel: usb 3-2: new high speed USB device using 
ehci_ hcd and address 7

The interesting part is the very last line. Could Apple have locked the filesystem 
somehow so that only iTunes can write to it?

I note that others have said they are able to use the HFS+ filesystem and write to 
it. But I also know that Apple is constantly making changes to the iPods, sort of 
slip-streaming them in without saying anything. And I bought this just last week 
from a store with a pretty high turnover rate.

Actually, to save typing I just edited it to be the iPod line. :)

Now it says:

/dev/sda3	/media/iPod	auto	rw,user,noauto	0  0

So the mount point is still /media/iPod. Or should it be just /media? Maybe that's 
what's wrong. Except those files were never visible before, even going deep into the 
folders.
