ok i just bought a 40gb hd for my pc and im installing it. when i put it as primary master and my other 20gb hd as primary slave it won't boot up righta nd it just stalls when it says checking "ide drives". then when i disconnect the 20gb and have the 40gb alone it works. then when i put the 20gb and take out the 40gb it works too. can someone tell me how to make it so i can have both working @ the same time. i would of put the 20gb hd as secondary master but the cable is weird and won't be able to reach my cdrw.
