I've seen these symptoms before. 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.
Cheers,
Matthew
