i purchased a new WD 250 sata drive. setup: the sata drive is the "master" or OS install. but i have another 250gig HDD that is an IDE connection. if i connect the sata drive and the IDE drive the pc will not boot. says that it needs to find a bootable drive. why is that i cannot have these 2 drives connected at the same time? the IDE is marked as a slave. Mobo = K8N Western digital gig 300 mb sec. ( jumper is set to use 150mb sec.) motherboard does not support sata 2. 2nd HDD is a 250 gig Maxtor IDE drive.
