I really hope this is a joke post ... because you cant seriously be considering using the software that comes with your hard drive. If by chance you are let me just point something out ... ITS A HARD DRIVE THEY ARE ALL THE SAME!!!
Im not trying to be rude or flame so please dont take it as such, but think a little, that software was made for soccer moms and stupid windows users that dont know piss all about formating drives. Ive had maybe 50 drives in my lifetime and not once have i ever used any of the software they bundled with it.
The answer to this problem btw would be to use fdisk or gparted, or even grab yourself a copy of hirens boot cd.
In closing you might want to consider throwing your bt3 cd in the trash and moving to an easer distro like ubuntu ... backtrack is NOT for beginners.
