my computer is a compaq presario with xpsp3 and 256 ram.
i used driveimage xml to create a backup image of my hard drive C:. do i also need to make a backup of my hard drive D:? i thought the D drive was specifically to make a "one time" copy of recovery CDs, and once that is done (i've already made the recovery CDs), it is no longer of any use, and basically wasted space.
