I am the HD KILLER
Another dead drive.
Seagate 500GB, failed the Seatools test utility.
Submitted RMA, need to package and send off to them for a replacement. This is a refurb I got for the previous one that failed.
Original 123GB Hitachi died, but I think it was previously dead and I just mixed them up (had 2, one “good” and one “dead”).
