To wipe the drive some ways include; boot a win98 startup disk, run fdisk
and delete all partition information found (as long as NTFS is primary). Or
boot the Windows 2000 CD-Rom or setup disks and when you get to the point,
delete the existing NTFS and or other partitions found, then abort the
install. Or use a utility named delpart. Once removed you can partition and
format the drive as you wish.

the root and drill down to it)
