I suspect that may be dependent on the nature of the failure. For
example, if /boot is corrupted, the BIOS will still boot from the broken
disk's MBR before failing later.

Most BIOSes now enable you to disable individual SATA ports, so you could
disappear the disk without unplugging it, although I'm not sure why you'd
want to leave a broken disk in the box.
