That's exactly the way I upgraded to W2K Professional. Did a clean
install on a new hard drive of Windows 2000 using NTFS and then
just installed my old hard drive as a secondary HD an copied files
from the old to the new. Easy and simple.
But, I hear that it's dangerous to put a second hard drive in on
your motherboard that has an operating system on it as it could
corrupt the hard drive(s) when booting up a system with two hard
drives, each with an O/S on it.
I've done it several times, but the 2nd HD was on a RAID
controller. Maybe that helped it. I also noticed that with the 2nd
HD installed, if I clicked on the partition with the O/S on this
secondary HD, it'd crash the system. No harm came from it though. I
was just careful to not click (in Explorer) on the paritiion of
another HD containing another O/S.
I believe there's even a warning about this in my GHOST program. I
know there's a warning about this at the Ratified GHOST tutorial at

reading for anyone using GHOST.
