See Table 204 in https://people.freebsd.org/~imp/asiabsdcon2015/works/d2161r5-ATAATAPI_Command_Set_-_3.pdf

Return values 0x80 - 0x83 are variants of the Idle state and should be treated similarly to 0xFF.

Relevant code line:

hddtemp/src/atacmds.c

Line 119 in 6740688

state = ( (args[2] == 0xFF) ? PWM_ACTIVE : PWM_STANDBY );

Support WIN_CHECKPOWERMODE1 outputs 0x80-0x83

These are idle state variants, so treat them the same way as 0xFF.
