[ale] SCSI fun n' games

[Glenn C. Lasher Jr.]

Sounds to me like the motor jumper is not shorted.

Some older SCSI drives had a jumper which would supply the power to the
motor.  If that is not shorted, then the motor gets no power.

Alternatively, it *is* an old Seagate.  Could be "sticktion."  The older
Seagates have a tendency to fuse their heads to the platter.
