Comment 57 for bug 952556

@ 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?
