hdparam

disk hard drive spinning disks to identify the disks and partitions: lsblk sudo hdparm -t --direct /dev/sdb1 To turn standby mode on, we can use the -s 1 option. sudo hdparm --yes-i-know-what-i-am-doing -s 1 /dev/sda To adjust the amount of idle time it takes before a hard drive enters standby mode, we will use the -S option. The way we specify the number of minutes is a little peculiar. The possible values are between 1-255. Multiply the value by 5 and you get the number of seconds your hard drive enters standby mode. sudo hdparm -S 200 /dev/sda /dev/sda: setting standby to 200 (16 minutes + 40 seconds) GUI 'disks' utility
