Thanks for all your comments, people.
I looked through my goodies box and found two HDDs - from RISC PCs surplus
to requirements, and known good (at least last time I looked). One was from
my dad's Kinetic, which I now have with my original HDD, and the other from
my brother, who has defected to Apple Mac ;-( . I still have the PSU I
replaced. So I will have a play over the w/e and seee what I can do. I also
note druck's comment and Chris's about earthing. (I've run into this one
before professionally, when some eejit connected my carefully-designed box
of tricks between two totally independent earth systems (don't ask), and
blew every fuse in sight. The box survived!)
I may well be on the phone to Chris on Monday.. :-(
Cheers
Julie
