I've been wondering:

The # atactl sdo setstandby 120 command issues an ATA standby command, which per the ATA specification is supposed to place the drive in standby and set or disable the timer value. I wonder if Sabbel could force the drive to enter standby mode after a failure of the timer to do so, using the # atactl sd0 standby command, which issues standby immediate, a different ATA command to the drive.

Without the firmware update, issuing an ATA identify command should be safe when the drive is operationally unused (unmounted). I wonder if, after a failure to enter standby, if an # atactl sd0 (the default identify command) might show power management disabled or the power management level set to a range that prevents the drive from re-entering standby mode.
