Its not supported...

Drive ID:

Model=ST3250824A, FwRev=3.AAE, SerialNo=5ND512MY
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4
BuffType=unknown, BuffSize=8192kB, MaxMultSect=16, MultSect=16
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=268435455
IORDY=on/off, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 *udma2 udma3 udma4 udma5 udma3 udma4 udma5
AdvancedPM=no WriteCache=enabled
Drive conforms to: Unspecified: ATA/ATAPI-1 ATA/ATAPI-2 ATA/ATAPI-3 ATA/ATAPI-4 ATA/ATAPI-5 ATA/ATAPI-6 ATA/ATAPI-7

* signifies the current active mode

Example:

/opt/sbin/hdparm -B 140 /dev/ide/host2/bus0/target0/lun0/disc

/dev/ide/host2/bus0/target0/lun0/disc:
setting Advanced Power Management level to 0x8C (140)
HDIO_DRIVE_CMD failed: Input/output error


Which means this does not work:

/opt/sbin/hdparm -B 164 ${internal_hdd}
/opt/sbin/hdparm -B 114 ${internal_hdd}

But you can replace it with this:

# setting standby to 120 (10 minutes)
/opt/sbin/hdparm -S 120 ${internal_hdd}

Or any other number you see fit. Remember the more spinning down (lower value), the more wear on the drive...


BTW, acoustic management isn't supported either?

/opt/sbin/hdparm -M 130 /dev/ide/host2/bus0/target0/lun0/disc

/dev/ide/host2/bus0/target0/lun0/disc:
setting acoustic management to 130
HDIO_DRIVE_CMD:ACOUSTIC failed: Input/output error
acoustic = 0 (128=quiet ... 254=fast)

Wow! That stinks.

IMHO, enabling APM on the 160G model is the perfect compromise between heat/power and drive wear.

I also have a 250 Gb model, but a with a different HD.
Mine has a Hitachi Deskstar T7K250 (ref HDT722525DLAT80)
It can do APM etc.

So I guess the question is can one figure beforehand which drive is in?
