@jokeman:
Some newer drives are very quiet about the clicking.

I would suggest inquiring on sourceforge, in hdparm's forums. The bug
of not being able to change APM levels is different. You may even want
to file a bug (or check to see if a bug already exists) with the hdparm
package.

@General
It would be a good idea to bear in mind the whole issue of drives which
cannot change their APM status. This bug still hasn't had the 'ugly
fix' released for Ubuntu, which is important to get done. But even
when that's done, the deeper issue of frequent disk access needs to be
addressed.

Any news on progress for this?
