I have just installed a Western Digital Raptor S-ATA hard drive on an Asus P4C800-E mobo. I installed Win XP pro on this hard drive. Now, I have a 120 gb IBM hard drive I want to install as a second hard drive for storage. I installed it and the Bios recognizes it, but I don't know what to do now so that Win XP recognizes the new hard drive. Do I have to partition and format it? Thanks for your help.
