Hm..probably I'm stupid guy, but BTW I wont to ask stupid question which
I have already for a long time.

I use promise driver from libata. So, drive connected to promise
controller is /dev/sdX. hdparm doesn't want to manage parameters of a
such drive. I've checked blktool - the same result.
So, is it problem of driver (something not implemented yet) or I have to
use something different?

blktool aims to be an easier to use, and more generic version of the 
existing utility 'hdparm'.  For example,

	$ hdparm -c1 /dev/hda
		becomes
	$ blktool /dev/hda pio-data 32-bit

	and

	$ hdparm -L0 /dev/hda
		becomes
	$ blktool /dev/hda media unlock

The utility is currently still fairly specific to IDE devices (as
hdparm is), but that will change in the coming weeks as SCSI, I2O, and
possibly some bits of hardware RAID control are added.

The audience for this application, like hdparm, is fairly narrow, 
specific to people who tweak their storage devices and _know what they
are doing_.  Improper use of this tool, like hdparm, can turn your
disk into a doorstop.
