I don't have
on my notebook and on my pc. What should it do or did it do, until which
version of openSUSE?

It was removed in 11.4, and it had been used for setting different hdparm
parameters when on battery/AC - more dangerous than useful.

I don't really understand why the hdparm manpage says: a very poor
choice for use with Linux.
Isn't it a poor choice for BSD or Windows too? Does Windows change this value?
Sometimes I boot Windows 7 on that pc, but the value is still at "8" (got the
value via "hdparm -J").

I think that window$ filesystems don't access the disk as often as linux ones
(for example writing journal by ext3/4 wakes the disk every few seconds, I
guess), so they don't wake it so soon after it is put to sleep.

I don't know what to think apart from that.

I'll add Robert to CC, I heard he had some experience with this.

Robert, what You think we should do about this?
