I have an HP x4000 workstation with a 70gb Sata hd. I want to add two 250 ata drives for extra storage. When I plug both of them up (both jumpers are set to cable select) and let it boot up, I get a SMART failure. If I enter setup, neither of the drives show up in the ide devices. When I plug in only one hd (doesn't matter which one), it works fine. Am I missing something or some setting I need to change? Any help is appreciated. Thanks.
