ahhh! WIMPS!;-)
I've done this for years! When I was the administrator
of a Strictly Mac Network, (caps for emphasis) I
popped on and off SCSI stuff all the time (I only had
one 8mm tape backup and two servers I needed backing
up. We were still LocalTalk at the time, so copying
across the network was not a good thing) I would take
the drive off of one server (quadra 950) and
>>quickly<< (you know, to get it plugged in between
the electrons...) into my other server (some kind of
SuperMac or other clone, I can't remember) This went
smoothly and flawlessly for several years and only
required a reboot on the rare ocasion when the
electrons were faster than I guessed. In fact, I
continued to do this even after we finally upgraded to
ethertalk! (the network wasn't segmented and 2GB of
data everyday slowed things down a bit!)
Now, for those of the PC bent, I would troubleshoot my
PCs by opening the case and unplugging and plugging
back in video cards, IDE cards and a special POST card
that I used to fix dead MoBos. Talk about exciting!
Open up a computer, start it up, and while it's still
running, quickly pop out the video card and quickly
(again, to get between the electrons!) pop in a more
generic one to make sure it wasn't a video card
problem!
I never had a problem! (well, not that I know...if
there was a problem, then the device was already not
worth salvaging anyway, said the fox about the grapes)
Of course, this is my own experience and as they say,
YMMV!
