Moving data to new disk.

Currently have 3 hard drives. Ide (c), 2 scsi (d&e). Want to add 2nd ide drive and copy current (d) to new drive. At that point ide drives would now become (c&d) and scsi (e&f). Have tried DriveWorks to accomplish this but when I boot, I’m unable toget to windows. System stops at “c” prompt. Called DriveWorks tech support and they claim this cannot be done because windows has been pathed to current (d) drive. They suggest that I reinstall windows (98 2nd Ed). Unable to do this as my os would now be on (e) drive and cannot even boot to windows. Is there a way that I can accomplish what I’m trying to do? Any help would be appreciated. Thanks
