Hi. I think your problem is the similar to mine. WHen i am tryin to issue command via hdparm i see next thing: $ hdparm -C /dev/sda /dev/sda: SG_IO: bad/missing sense data, sb[]: f0 00 01 00 50 40 ff 0a 00 00 78 00 00 1d 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 drive state is: unknown While the expected output is the following: $ hdparm -C /dev/sda /dev/sda: drive state is: active/idle There was a commit in v6.6.44 and it was backported to the v6.10.3 and v6.1.103 accord…

It’ll be fixed in next kernel and it is in testing already.
Anyway not sure why you not able to spin down your HDD.
I have no problem with
sudo hdparm -S 1 /dev/sda
command
