[clug] Testing the VFAT patch on iPods

My iPod is set to operate as a disk. It just appears as a normal
external USB drive to anything not running iTunes or otherwise
specifically looking for the model of the device (Rythmbox and the
like).

I can't see anything extra that needs testing for the disk mode of an
iPod beyond what's required for a normal USB drive (the files work in
*nix, Windows, OS X).

The more interesting thing would be whether or not all the 34
character test files will load via iTunes or libgpod in to the iPod's
DB without some sort of corruption. When I'm fully unpacked (still
unpacking at the Melbourne end of my move) I'll give this a go unless
someone else has already posted results.

Cheers,
Dave
