Thanks for the responses so far. Hoping to get my new drive today, and
will be starting the rebuild process when it arrives. I did try booting
from a live USB drive but the BIOS on the system isn't even recognizing the
drive anymore. Also tried moving the drive to another system and booting
from the live USB drive there, but on this system I can't even get past POST
with the drive connected. Still might try a few more things, but that's why
I said "what looks to be an unrecoverable hard drive crash" in my original
Definitely plan on adding scheduled backups to another system / drive.
