I wrote ftp://ftp.jurai.net/users/winter/atautil.tar to manipulate ATA
"APM" settings. APM is drive managed power configuration.

I call a simple shell script via apmd to enabling idling when the laptop
is on battery.

'atautil' also supports reading the drive tempreature from IBM/Hitachi
Travelstars.


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
