It appears to be a "feature" of certain Motherboards. If you're lucky there will be some BIOS options you can toggle to make it behave better -- usually to do will telling the motherboard *not* to do any sort of RAID stuff itself. Otherwise, look for BIOS updates, or switch to a different Motherboard. Systems supplied with hot swap drives (meaning SATA rather than IDE) tend to work better. Or install a hardware RAID controller. I've also a feeling that there's a behavioural difference between 'only one drive present' and 'one working drive and a blank disk' but haven't really tested that theory out, as we solved the original problem by other means.
