Tama si Jepoy. IDE cable ang problema dyan. Kung tama naman ang lagay mo sa jumpers, yun na talaga ang problema.
Here's another way: instead of respectively fixing your hard drives as master and slave, you can try to configure your using cable select instead. Naka-cable select yung jumpers ng HDDs mo then the connector, the blue tip is connected to the mobo then the connector at the other end is connected to the master drive. Yung nasa gitna is connected to the slave drive.
