Charles:

I don't know. Might be better. I put the idea to the list to see who would 
comment as well as because I believe the power-cycle test is good in itself.

My thought was that most problems I've run into would be apparent soon after 
powerdown. In addition, _some_ problems are related to minute tolerance 
differences.

It used to be (apocryphal?) that the old 9332(?) drives had a reputation for 
failing after spindown/spinup when they'd been in use continuously for long 
periods. The fix could be as easy as a whack on the case with a rubber mallet 
or simply letting it shake itself during the power cycling. If any such 
problems still exist with drives today, the powerdown/up would serve a 
secondary purpose doing a "shakedown" as early as possible in the process.

OTOH, a full temperature test might actually generate trouble. (I have no idea, 
purely random thought. DASD technologies today are past me.)

I'd be interested in knowing if it really added to the process.

Either way, finding out that parts need to be ordered early could mean that 
everything is available as soon as the box arrives at the new site. Might as 
well make use of the downtime while in transit.
