Yes, indeed, this drive *does* spin up. Actually, I've cycled the power
on it about a half-dozen times by now, messing with this imaging
project. I have noted in past threads some consternation with this
drive, and it's just what I want to 'manage' with these imaging
efforts. When (I guess not if :) this drive goes bad, I'll have the image.

Oops, my mistake. I transcribed that from my notes incorrectly. Should

That's just it, though. I'm so much of a VAX newbie. I have *no*
knowledge of what is and isn't on these system, since I've been scared
to even power them up until I know more about what I'm doing. Thus the
desire to get the drives imaged *before* I do something that I can't
recover from. I just don't know what is dangerous or not, yet.
Still, we could hide under our beds everyday trying to avoid life's
little risks, right? I guess I'm going to have to bite the bullet and
just crank one of these systems up and see what I've got. I have
successfully imaged the drive on the 3100, so at least I can give that
system a try.
I'll have to be a quick study with VMS, if that's what's on it. I do
have a mostly complete set of VMS v4 (I think) manuals, so I'll just
have to dig in, assuming that is indeed what I have on the system.

Time will tell.
Thanks for the good words.
