well, It does not work on amd64. or - with my HDD.


#aldan ~/atautil> ./atautil -f ad0 identify
atautil: IOCATAREQUEST: Inappropriate ioctl for device


at same time atacontrol says that it is
#aldan ~/atautil> atacontrol list
ATA channel 0:
    Master:  ad0 <ST9100822A/3.01> ATA/ATAPI revision 6

Are there any ideas why IOCATAREQUEST ioctl fails - as I see all ioctl
request from ad_disk driver are redirected to ata-all:ata_*_ioctl
function. At same time I cannot see any ifdefs in ata* files which
disable processing this ioctl..

May be this is an issue with hard driver() it is
#aldan ~/atautil> atacontrol cap ad0

Protocol              ATA/ATAPI revision 6

so it CAN support power management.
