Thanks - that was just what I was looking for!  That'll save me an awful 
lot of hassle in future, especially as I'm eyeing up the CAM integration 
patch.  In the meantime I'm successfully but slowly retrieving my data, 
I'll just have to be patient, but it's reassuring that I can build a new 
ZFS array with confidence.

Cheers,

Chris.
