Adding 3 hard drives to a proliant ml350

I have three drives set up as a Raid 5, on a Proliant ML 350, running Windows 2003 server. Partitioned as a C and D drive. I would like to add three identical drives and if possible add them to the D drive. Is this possible and how do I do this? Thanks Garry
