Below is a link to download the MaxBlast 4 CD from Maxtor. It is bootable and from what I have read you should be able to fix it with that. You should be able to REMOVE DDO with the cd as it's NOT needed in XP.
There is another possibility.....Could it be a corrupt install of WindowsXP that is not allowing you to see the full drive size?
Asus has a registry change that others have been told about for this.
Just go slow with this thing as you can loose alot if not careful.
