But you didn't RTFM --> man hdparm:

-C Check the current IDE power mode status, which will always be one of
unknown (drive does not support this command), active/idle (normal oper-
ation), standby (low power mode, drive has spun down), or sleeping (low-
est power mode, drive is completely shut down). The -S, -y, -Y, and -Z
flags can be used to manipulate the IDE power modes.
