Hi guys. I bought a used 40GB WD HDD for my old p2 computer that I'm going to transform into an Arcade computer... The thing does not detect it... I plugged it into my computer I use everyday and everything works fine... any ideas ? Oh, and BTW It used to have a 20GB maxtor hdd which is on last legs which is why I am replacing it. dual p2 333mhz 4x 128mb ram ASUS p2L97-DS motherboard
