reselect on
Seagate drives are known for their slow 'spin up' cycle. It's
possible that the drive isn't ready the first time you boot. Have you
tried just warm booting again after the system comes up- without
using the reselect? If that works, there is a jumper on the 2091
that you can set which will make the controller wait longer for the
drive to spin up. I don't have the docs here at home, so I can't tell
you which one it is…
