sectors during a Write command. The Error Recovery page is discussed
in Appendix C.1.
If the system supports disconnection, the drive can disconnect and
reconnect while executing this command. The drive disconnects when
either an internal error recovery procedure is required or the drive's
internal data buffer is full.
The buffer-empty ratio in the Disconnect/Reconnect page determines
when the drive reconnects. Section C.2 documents the Disconnect/Re-
connect page.
If there is a reservation access conflict, this command terminates with a
reservation conflict status and no data is written. For more information
about the reservation conflict status, see Section 3.2.
