Wytron DVD-688 hard drive problems

Hey there everybody.

I have built a 10 target DVD duplicator using a Wytron DVD-688. I used 10 plextor PX-800A drives and a crappy old 10 gig hard drive. Things worked fine untill the hard drive crashed. I tried to install a new seagate 250G HDD but the controller doesnt use it. It shows up when it detects the drives, but doesnt create any partitions to be used.

I am at a loss. Do I need to format it with special tools before I install it?

Any help would be greatly appreciated
