@ Dagnachew, Swami, Steve:
I've noticed that in Dagnachew's output the power management has changed
to 1 while his acoustic management setting is 128 after changing
etc/hdparm.conf.
My disk is still spinning down after adding apm_battery=128.
Can it be that some disks interpret a power management setting
mistakenly as acoustic management or both?
My current, abridged hdparm -I:
...
Capabilities:
LBA, IORDY(can be disabled)
Queue depth: 32
Standby timer values: spec'd by Standard, no device specific minimum
R/W multiple sector transfer: Max = 16 Current = 16
Advanced power management level: 128
Recommended acoustic management value: 254, current value: 0
DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 udma5 *udma6
Cycle time: min=120ns recommended=120ns
PIO: pio0 pio1 pio2 pio3 pio4
Cycle time: no flow control=120ns IORDY flow control=120ns
...
Any ideas?
