I just spent the better part of the day installing a new 20GB hard drive into an old Thinkpad 600 that had a 6GB. I have W2K Pro since there's not much ram to run XP efficiently. Hardware installation was a snap . . . the biggest time consumption was downloading all the updates, drivers and utility programs that took most of the afternoon. Anyone migrating W2K . . . make sure you have the Service Pack 4 before doing anything.

BTW, I have nothing but good things to say about Acronis True Image 10 (there's a 15 day trial version to download) for doing disk image and file archival for restoration. I like it better than Norton Ghost.
