I hope so!

The BIOS on this SuperMicro system is not terribly helpful so I am not 
quite sure how to do that other than pulling drives.

After a power outage where the system was down for maybe 15 minutes, 
it failed to boot properly.

There was a failing boot drive still installed which I had mostly 
ignored other than disabling it.  But the BIOS and boot loader did not 
seem to know that it was disabled and tried to slowly boot from it. 
Another anomally was that it appeared that the BIOS (or something) was 
causing all of the data on all the disks to be read in turn before 
booting.  I have never seen anything like it before.

By physically removing the flaky boot drive and popping out the 
hot-swap drives, I got the system to boot.  I found that one of the 
hot-swap drives no longer spun up.  The BIOS and boot loader did not 
handle this well.
