Currently owning this piece of "fine machinery" (sarcasm)

Western Digital Scorpio Blue WD3200BEVT-00A0RT0

Recently checking out SMART status I've found out that

at
Code:
 9 Power_On_Hours          0x0032   081   081   000    Old_age   Always       -       14147
I have

Code:
193 Load_Cycle_Count        0x0032   001   001   000    Old_age   Always       -       [color="Red"]3138670[/color]
Any help on at least stopping the rate of this value will be much appreciated

This is a common issue with drives that are meant to be used in laptops. You can try to turn off APM in the drive using sysutils/ataidle

# ataidle -P 0 /dev/adaX

Where adaX is the device for your drive.

The setting may not survive reboot, in that case you can have sysutils/ataidle started automatically at boot with these lines in /etc/rc.conf:

Code:
ataidle_enable="YES"
ataidle_devices="adaX"
ataidle_adaX="-P 0"

Depending on the drive, Western Digital's wdidle3 command can be used to set the idle timeout, which is the number of seconds of "idle time" before the drive heads are parked.

Will it work under freebsd FreeBSD 9 providing that atacontrol was replaced with cam? And if supplying
Code:
ataidle_devices="adaX"
via rc.conf - is is comma separated for multiple drives?
