I don't know much about this system, but I've done my fair share of data recovery and disk imaging.
Is it a standard PC style hard drive interface? I've managed some pretty crazy repairs on drives too.
Cloning hard drives is pretty easy, I say this without knowing your situation
, and I can walk you through it in a bunch of different ways using Windows, MAC or Linux. Honestly Linux is probably the easiest using Clonezilla or ddrescue, but there are gotchas with each of the methods.
Do you have pictures of the drive and or interface? A quick search on googles didn't help me much.
