Followup FYI:

So it appears to be either a duff USB interface or a problem with my
Mandriva 2.6.12-29mdk-i686-up-4GB kernel...

Doing the same tests on another machine with a 2.6.17 kernel has proved
everything to be perfectly good. badblocks always completed ok. Both
fdisk and cfdisk correctly reported the lack of a disk label and the
lack of a partition table and offered to create the data as required.

Cheers All,
