You have not said if these are physical drives or they are partitions of one or two physical drives. If they are physical drives, see if they are recognized in your BIOS. You also have not mentioned if these were operating drives already used with the current operating system, if they are new, if they are from another system, or if they have other operating systems installed (a linux formatted drive will not show up in windows, except possibly as an 'unformatted' drive).
