It's either your choice of BIOS settings (more later) or it needs to be prepared in disk management (nothing about that here since you can google that.)

The BIOS choices can disable the IDE since many machines do IDE emulation on the SATA channels. Most new machine builders are only now catching up about how this emulation means we won't be able to use the IDE channel in most boards.

Beware that changing that setting can have deleterious affects on Windows so be sure you know how to change it back.

Then again, almost any 80GB IDE drive is long over its design life so what's to say it's not dead?

And lastly. IDE jumper and cable rules seem to be passing into arcana. Ran into a tech that never heard about it.
