Oprire HDD nefolosit in Slackware

Va salut,

Am configurat un mic server pentru acasa cu Slackware 14.1. Ca sa fiu scurt e vorba de un HP cu procesor E8400 cu doua HDD-uri si 8 GB RAM.

Pe un HDD (al mai mic) am Slackware-ul in 4 partitii (/ , /boot,  SWAP, pagina web) tot acolo sunt si joacele copilului. Pe al doilea HDD am doar sharingul de SAMBA si puscariile vsftpd-ului.

Primul HDD este un WD green (care inteleg ca are obiceiul de a-si reduce turatia cand nu da din greu) si, intrucat tine log-urile masinii, nu poate fi oprit. Al doilea as dori sa-l opresc dupa un timp de inactivitate.

Cum pot sa fac treaba asta?

Multumesc

hdparm
-S Put  the  drive  into  idle (low-power) mode, and also set the standby (spindown) timeout for the drive.  This timeout 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 circum-
  stances, 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 "timeouts are disabled": the device will not automatically enter
  standby mode.  Values from 1 to 240 specify multiples of 5 seconds, yielding timeouts from 5 seconds to 20 minutes.  Values from 241 to 251 specify from 1 to 11 units of 30 minutes, yielding timeouts from 30 minutes to 5.5 hours.  A value of 252 signifies a timeout of 21
  minutes. A value of 253 sets a vendor-defined timeout period between 8 and 12 hours, and the value 254 is reserved.  255 is interpreted as 21 minutes plus 15 seconds.  Note that some older drives may have very different interpretations of these values.

hdparm -S 24 /dev/sdb

Teoretic ar trebui ca dupa 2 minute de inactivitate sa se opreasca automat.

Multumesc!

Confuzia a plecat de la /etc/rc.d/rc.acpid de care m-am impiedicat prin sistem si nu-i gaseam deloc "acpid.conf"-ul aferent ....    deh... ultimul Linux instalat e casat de mai bine de 10 ani.

Sta bine in /etc/rc.d/rc.local sau e de preferat alta locatie?

rc.local e ok.

Nu stiu cum face Slackware modern dar as recomanda folosirea chestiilor gen /dev/disk/by-uuid/f6320..... (afli din blkid UUID-ul) in caz ca sdb nu e sdb intotdeauna.
