You believe the disk should support APM.  The disk claims otherwise.
Since you don't actually provide any information about the device
(dmesg?  full atactl identify output?) that would indicate a problem
with the device driver, the only suggestion anyone is likely to make
is that you should take it up with the disk manufacturer.

Disk rejects apmset request

Hi all,

I have one disk (wd2) that does'nt shut down. It has Power Management
feature but does not reply to apmset. It's a brand new disk ; I believe
it should have the feature.
Could someone help me ?

Thanks.

   Dear All,
   Is there any way to autostop the HDDs after some time of idleness ?
   Under Linux it seems difficult since the hdd is needed to be
   ready/working all the time even when the system is idle. It seeC9s 2
   other points make the use of thois function not really possible.
  
   Since I will use a SSD disk (no noise and fast) of 32 GB to install the
   main system, the rotating HDD will only be a data system (I'll mount
   home or even less if required ...). In that configuration under OpenBSD,
   can I make use of this function for my such config ?
