Trying to install a new sata maxtor 250gb hard drive into my new build computer that also has a sata 40gb samsung spinpoint as boot drive.The problem i have is that while i installed xp on the 40gb drive without a problem i cannot get the 250gb to be recognised .Initailly it was seen under hardware manager but only as 137gb not 250gb so i loaded new drivers and now its not seen at all .My motherboard is dfi lanparty UT NF4 SLI-D i havent used sata before so i may be doing something stupid any suggestions?
