Thanks for this. I recognise the stuff from dmesg. I was trying to
mount the ffs disk because it is handy. I have another flash device
that I would like to partition as a 2 or 3 partition drive, mkfs
and then copy data to it from (hd0,0). Then I want to recreate
hd0 as a multi-partition drive, install 64-bit f9, and then copy
the data back from the flash drive.

The stumbling block for me was that I didn't understand how the usb
devices are named and accessed in Fedora before they are mounted. 
I think I understand naming now.
