# hdparm
|
|
|
|
> Get and set SATA and IDE hard drive parameters.
|
|
|
|
- Request the identification info of a given device:
|
|
|
|
`sudo hdparm -I /dev/{{device}}`
|
|
|
|
- Get the Advanced Power Management level:
|
|
|
|
`sudo hdparm -B /dev/{{device}}`
|
|
|
|
- Set the Advanced Power Management value (values 1-127 permit spin-down, and values 128-254 do not):
|
|
|
|
`sudo hdparm -B {{1}} /dev/{{device}}`
|
|
|
|
- Display the device's current power mode status:
|
|
|
|
`sudo hdparm -C /dev/{{device}}`
|
|
|
|
- Force a drive to immediately enter standby mode (usually causes a drive to spin down):
|
|
|
|
`sudo hdparm -y /dev/{{device}}`
|
|
|
|
- Put the drive into idle (low-power) mode, also setting its standby timeout:
|
|
|
|
`sudo hdparm -S {{standby_timeout}} {{device}}`
