I have exactly the same problem. I used partition magic to create another partition in FAT for Bootmagic and now it doesn't show my second hard drive. In 'My computer' it shows my main partition (XP) and Bootmagic partition.
Drive Image 2002 still sees the second hard drive but like what BrianW said; in this format:\\.\disk2part1. Partition magic show the second hardd rive as hidden but it cannot unhide it.
Can anyone offer advice to BrianW an me?
Is there a manual way to show the second hard drive?
