A note on the 250 gb model and APM

[clausbruun]

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?

Hmm makes me wanna return mine
