You can automate that procedure if you want--there are companies that sell
disk units that randomly power down and up.
If you try to get a disk driver certified by Novell for Netware, one of the
tests is to hook a disk controlled by your driver up to such a device, and
mirror it with another disk, and then run disk stress tests for a long time,
while the torture device is doing its thing.
There must be no data corruption, and, I believe, no significant loss of
performance while the drive is taken down and up.
