For some reason it wouldn't let me do that. The OS was Windows 2000 NT so maybe they prevent formating since it's so security minded.
Here's what I finally did - hope I didn't get myself into trouble. I had a version of DOS 6.0 and loaded that. On setup it said that the hard disk was not compatable and do I want to fix it. Said yes, and that 's all it took! I then could format the hard drive.
Now I've got to reinstall Windows 2000 NT. I need to think a bit since the CD-ROM drivers are gone. Hmmm...hoping the setup CD's work....
Thanks for the help!
