John,

It depends.  :-)

If the disk just dies there's not much you can do.  If, however, the disk
is still functional you can use Lund's De-Frag/X CLONEDISK capability to
copy, sector-by-sector, from the bad disk to a new disk, and put the new
disk in place.

Works great but the process really needs support from Lund to work best.
