When the IMMED bit is set to “1” (TRUE) in a command block, the drive returns

GOOD when the command is first interpreted. As the command is being executed, the

drive returns BUSY to successive commands until operation of the first command is

complete and the drive is ready to receive a new command.

Refer to Section 2.31 REQUEST SENSE for details on deferred error reporting.

The DRM/DR-U Series supports only those In-Phase and Out-Phase Messages that are

listed below and on the following page. The drive will return a MESSAGE REJECT

for any messages received other than those listed.

Message Msg 05h + 09h will cause the drive to go to BUS FREE PHASE without a

retry.
