If the broken disc is part of a (non-mirrored) user volume set you
might probably also be able to use VOLUTIL COPYVOL to create a raw
disc copy... As far as I recall (being at home) it will allow a disc
to disc copy (as long as the user set is VSCLOSEd).

You'd need to temporarily have both, the old and the new disc hooked
to the system, though. And you'd have to make sure that there will be
no VSOPEN or alike after the COPYVOL (as long as both drives are still
visible to the system).

Haven't done it myself so far, but might copy faster than via DDS.
I also do not know how COPYVOL behaves when old disc gives media read
errors during the copy operation...
