If you can still do some testing, what happens if you unplug power to
the failed drive and replug it while the system is still running?  Does
hotplug event get triggered and the drive gets recognized again?  If so,
does unplugging and replugging the SATA controller only (w/o powering
down the drive) achieve the same thing?
