Combo RAID1 and standard Drive setup problem - Unallocated Drive (Reposted)

Hi everyone,

Putting together my new system:
core i7 920, Gigabyte EX58-UD4P, MSI R4850, Patriot DDR3 3x2GB PC3-12800,

Its my first home build, fortunately after putting everything together it boots up appropriately on first try into Windows Vista Ultimate 64bit

My hard drives are WD1001FALS x2 (RAID 1 storage) and WD6400AAKS x1 (non-RAID Main drive)

My computer sees the main drive and the storage drive in the Disk Manager, however only the main drive where vista is installed is "allocated". The RAID storage drives are recognized and listed but are "unallocated". What do I need to do next to make this setup useable? The only thing I can see is to "make a new simple drive" but then the warning says this is only for a SINGLE drive. Is this the option I want to make things work even though it's 1 logical drive made of 2 physical drives? Is there a format button? do I need to format the discs to get them allocated.

I never get an option to "format" I will attach 2 pictures of my screen. Each picture shows which part of the disk management was right clicked (see mouse pointer) and I get 2 different kinds of submenus. Neither of them offer the opportunity to format. Any thoughts?

Thanks...Doc
