Thanks for the info...

What I ended up doing was to run ODE at the ISL prompt, then ran COPYUTIL to
copy  the disk image to DAT, swap out suspect drive (it was still
operational). I found the COPYUTIL process documented at
http://support.mayfield.hp.com/, search all database with COPYUTIL as
keyword. Most of it is under Unix, but it is available under MPEIX .

Works great if your drive is still operational.
