I would take the 40gb hard drive (the storage one), plug only that one that one in, make sure the jumper is on master, then boot with a Windows ME, 98 or any relative version, Boot Disk. Then do a minimal boot, or whatever its called depending on the boot disk version. That should get you into DOS. From there run FDISK, which is just like partition magic, except it can only delete and create partitions for Windows. Once you create the new partitions format the drive ("format <drive letter>" is the command, if you didn't know), then when its all done, plug in the other drive, make sure that it's jumper is on master, and switch the other on slave. Then you should be able to boot the O/S on your new hard drive, and Windows should see the second drive, also might prompt you that it found some new hardware, but all in all it should work.
