This command disables all SMART capabilities within the drive including any and all timer functions related exclusively to this function. After receipt of this command the drive may disable all SMART operations. Parameters for drive failure prediction will no longer be monitored or saved by the drive. The state of SMART (either enabled or disabled) will be preserved by the drive across power cycles.
Upon receipt of the SMART DISABLE OPERATIONS command from the host, the drive sets BSY, disables SMART capabilities and functions, clears BSY and asserts INTRQ.
After receipt of this command by the drive, all other SMART commands, except for SMART ENABLE OPERATIONS, are disabled and invalid and will be aborted by the drive (including SMART DISABLE OPERATIONS commands) with an Aborted command error.
