My backup machine uses some recent, consumer grade, disks (it's better than tapes anyway). How can I detect if a disk is effectively stopped or not? I have found the command catcontrol cmd ada0 -a "E5 00 00 00 00 00 00 00 00 00 00 00" -r - but how to know it is reporting the state of the drive and not the state the driver assumes the drive to be? TIA, Olivier
