We were talking about this very thing not too long ago on this list.
Some have claimed this can happen if you:
a] Plug the cable in backwards - ie., the end with the single plug
should go into the motherboard and the end that has the two plugs
closer together should go into the drives.
b] Plug the wrong one of the two that are closer together into the
driver.
So I'd say try pulling out the cable and plugging it back in in a
different way.
Another thing to be sure of is that you have the UDMA 100 cable;
ie, one end should have a blue connector and that end should go into
the motherboard.
