NAME
atactl - a program to manipulate ATA (IDE) devices
SYNOPSIS
atactl device command [arg [...]]
DESCRIPTION
atactl allows a user or system administrator to issue commands to and
otherwise control devices which reside on standard IDE and ATA con-
trollers. It is used by specifying a device to manipulate, the command
to perform, and any arguments the command may require.
DEVICE COMMANDS
The following commands may be used on IDE and ATA devices. Note that not
all devices support all commands.
identify
Identify the specified device, displaying the device's vendor, product,
revision strings, and the device's capabilities.
idle
Place the specified device into Idle mode. This mode may consume less
power than Active mode.
standby
Place the specified device into Standby mode. This mode will consume
less power than Idle mode.
sleep
Place the specified device into Sleep mode. This mode will consume less
power than Standby mode, but requires a device reset to resume operation.
Typically the wd(4) driver performs this reset automatically, but this
should still be used with caution.
setidle idle-timer
Places the specified device into Idle mode, and sets the Idle timer to
idle-timer seconds. A value of 0 will disable the Idle timer.
setstandby standby-timer
Places the specified device into Standby mode, and sets the Standby timer
to standby-timer seconds. A value of 0 will disable the Standby timer.
checkpower
Will print out if the device is in Active, Idle, or Standby power manage-
ment mode.

BUGS
The output from the identify command is rather ugly.
