I have an external HDD connected through USB. There is that Gnome utility called "Disks". When working the disk is on the list on the left. If I click on "turn off" button, the disk disappear from the list and is no longer in lsusb output, and - most important - spins down, turning off.
What command(s) must I invoke from a script to turn off disk like that?
sudo hdparm -Y /dev/sdc
gives
/dev/sdc:
issuing sleep command
SG_IO: bad/missing sense data, sb[]: SOME HEX STUFF
Answer
Short lookup in gnome-disk-utility repo code, and:
udisksctl power-off -b /dev/sdX
In ArchLinux, /usr/bin/udisksctl is owned by udisks2 package.
