Denys and everyone,

Has anyone inquired with the folks at Lund.  As I recall, they had a product
called 'CLONEDISK' which might fit the bill for copying disc volumes.  I
know
that James Reynolds published some history on that product to the -L several
years ago.

Bill Lancaster can you address this?
