Check dmesg to see if the drives show any differences... If they are SATA drives check to see if there is a jumper which forces it into "compatibility" mode, slow mode, something like that... If they are SATA and you use an intel chipset motherboard check to be sure that the SATA header of that drive is set to AHCI and not IDE mode... Those are just ideas, things I have encountered. :)
