A couple of postings happened whilst I waa typing my replies.
OKAY...

1) - If Windows ignores an unformated drive - How am I supposed to get it instaled (in the machine) and then get it formatted?
Knoppix Linux (boots from CD without being installed) isn't spotting it either.
2) - Guest - Bensson - I will try putting both hard drives on the same connection with the new one as "Slave" and see if it makes a difference.
I'm off to sleep now, so will review advice and suggestions when time allows. (Tomorrow is Viking Festival in York (Jorvik) so might be out if rain holds off...)
Quack!
GtD.
