I am using a second HDD as a backup drive on my W2K installation. It's an older Maxtor that I'd like to replace with a Barracuda IV for speed and quiet. I've tried both just removing the old one and sticking in the new one, and I've tried deleting the partition first through disk managment. In either case I get unrecoverable registry errors, and end up having to recover my W2K installation from an image. Should I first remove it in Device Manager? If anyone can tell me the correct way to do this, I'd appreciate it.
