I've formatted and installed Win XP Pro on a 250 Gb drive. Can I add a new partition on that same drive? In other words, can I have drive C: take up only 100 Gb, and drive D: take up the other 150 Gb? Disk management recognizes the entire drive as C: and thus does not allow me to add/break-up the drive. Can this be dione in Windows XP or is there an after market program. Thanks for any help.
