Just curious, since you've said its a dell ... and server.. is it a power edge? do you recall the model? Maybe some lookups specific to that model might find something.

Too bad you don't have a dell hardware raid controller somewhere.. many moons ago, when the company I worked for had a dell contract.. we cloned by putting master drive into a server, letting the controller do a broken mirror sync ... and then manually break the mirror moving the newly cloned to drive to the next needed server .... 25 drives in an hour ... redhat, thankfully, so it was just a change of hostname and ip and all was good (not like windows where you'd have to newsid the box, etc).
