That will depend on what your bios does when the first drive fails and
whether you've had to move it to make it boot at all.  On the scsi
systems where I've used it, the 2nd drive will boot and everything
on the cable shifts up if the first drive fails or is removed.
IDE systems are different - and normally won't boot if a failed drive
is still connected.
