fdisk problem

[Nomad84]

I just put my new computer together this afternoon. So far, I've only installed the Raptor and not my storage drive. I am trying to partition it so that I can install Windows, but I'm having a problem. I am using the FDISK tutorial from fdisk.radified.com. I created the primary partition without any trouble, but I'm having problems creating an extended partition. Each time I try to create an extended partition, it freezes when "Verifying drive integrity". It hits a max of 16% before stalling out temporarily and returning to 0%. It will eventually just stay at 0% and I have to ctrl-alt-del to get out of fdisk. If I just create the primary partition and reboot, it shows up fine, but if I try to create an extended partition, after I reboot, no partitions show up. Where should I be looking for help?

I am using:

ASUS A8N-SLI Premium motherboard
WD Raptor 74gig hard drive
WinME boot disk
