I noted that when idle, my laptop HDD increases the Load_Cycle_Count
(193) approx. each ten seconds, as reported by smartctl. Have recently
read about the Ubuntu and APM mode for hard drives, I searched for the
tool to tune APM (that has functionality similar to linux' hdparm -B).

It seems that FreeBSD does not have a tool ? Am I wrong ? In case I did
not make a mistake, below is the patch that allows to manage APM state
of the hard drive using atacontrol.

Any chance to also handle automatic acoustic management at the same time?

Yeah, fast. :)

Whitespace error for the comment in the line of the ATA_SF_DIS_AAC define?

It seems that the patch goes to the waste-basket, so whitespace problems are
leaved as is. ATA code uses its own formatting conventions anyway.
