I've got 3 harddrives: 1 Raptor, and 2 750GB secondary drives. They're all SATA. They're all hooked up properly via SATA cables to the motherboard and are powered correctly via cables to the power supply. However, my computer (running XP SP3) only recognizes the 1 Raptor and 1 of the 750GB secondaries. I just installed the 750GB secondary that isnt being recognized. All three harddrives are recognized in BIOS. Can anyone think of what the problem might be?
