Hi Chuck,

The next line in my post after where you snipped was:

(The disk is from another FreeBSD system so is UFS2 and da2s1f is /usr
on the other system)

It contains a running FBSD 7.0 system - it's out of a spare box I was 
using for testing and it mounts/reads/writes fine using the other USB 
enclosure I borrowed. There's just something screwy about the enclosure 
I've bought (typical eh?)

Regards,

Mark
