replacement of ataidle for freebsd 9

[Eugene Dzhurinsky]

Hello, can somebody please advice how to disable APM power management for HDD
on laptops?

> camcontrol cmd ada0 -a "EF 05 00 00 00 00 00 00 00 00 00 00" -v
camcontrol: error sending command
(pass0:ahcich0:0:0:0): SETFEATURES. ACB: ef 05 00 00 00 00 00 00 00 00 00 00
(pass0:ahcich0:0:0:0): CAM status: ATA Status Error
(pass0:ahcich0:0:0:0): ATA status: 51 (DRDY SERV ERR), error: 04 (ABRT )
(pass0:ahcich0:0:0:0): RES: 51 04 00 00 00 00 00 00 00 00 00

What else should I try?
