Some time ago, I had a power interruption clobber my unRAID box, despite it being on an UPS. The parity and one of the three data drives were reporting that they were no longer valid. I tested them as best as I knew how, but never did manage to get the array restored. Since then, I've replaced all the hardware in the box, other than the drives. I dropped everything back in, with the faint hope that would magically fix the problem. Of course, it hasn't.

 

I've decided to just start over and have already initconfig'd the array. Adding the five drives to array nets me three blue balls (expected) and two drives saying "Not installed". On the "Disk Mgmt" page of unMENU, the two drives listed as "not installed" are also not in the protected array. It knows those drives are formatted with reiserfs. Should I just toss the drives or is there a way to either restore them or determine what their issue is?

Are you sure they have power?  Perhaps they share a splitter that is defective?

 

Do they respond with anything to an "hdparm" command, or a "smartctl" command? (both available as "button clicks" in unMENU)

 

I'd suspect cabling before the drives from what you've described, but then you did not attach a syslog to use for any analysis so that's only a guess.
