I have a seagate 157N in my Amiga and it routinely seizes if I power down.
As a result I never shut my machine down. However if the power goes out
or I suspect it will I end up doing the following to get it spun up:

(Don't do this unless you know what you are doing and are very brave)

Take the covers off.
Leave the drive with it's power, but remove the control cable.
Remove the grounding brush on the spindle top by unsoldering it.
With everything checked for shorts and other metal to metal contact,power up.
Using a good pair of needle nose pliers, gently turn the spindle.
Now that it's working, shut down and re-assemble.
(I leave the grounding brush off)
(Now pray)

For me, that one hand spin makes the next poweru-p successful at restarting the
drive. Gee, I ought to install a hand crank on the front panel.

Stupid Seagate drive.
I wish they would address the problem and offer a fix....
