Prøv at kig på hdparm ('man hdparm')

kommandoen 'hdparm -S 120 /dev/hdX' skulle gerne sætte spin-down tiden til
10 minutter.

Et lille klip fra 'man hdparm':

-S     Set the standby (spindown) timeout for the drive.  This value is used
by the drive to determine how long to  wait (with no disk activity) before
turning off the spindle motor to save power.  Under such circumstances, the
drive may take as long as 30 seconds to respond to a subsequent disk
access,  though  most drives are much quicker.  The encoding of the timeout
value is somewhat peculiar.  A value of zero means "off".  Values from 1 to
240 specify multiples of 5 seconds, for timeouts from 5 seconds to 20
minutes. Values  from  241 to 251 specify from 1 to 11 units of 30 minutes,
for timeouts from 30 minutes to 5.5 hours.  A value of 252 signifies a
timeout of 21 minutes, 253 sets a vendor-defined timeout, and 255 is
interpreted as 21 minutes plus 15 seconds.

Men der findes en del processor på en Linux maskine som skirver til disken
meget tit, syslog er en af dem. Hvis du vil bruge APM (BIOS strømsparing) så
skal du huske at kompile det ind i din kernel.

Mvh.
