NOTES:

1. Relative Addressing is not supported by the drive. Therefore, in all I/O

commands, the RelAdr bit must be 0.

2. RESERVE and RELEASE are supported, as are third-party reservations. Extent

reservations are not supported.

3. The RECEIVE DIAGNOSTIC RESULTS and SEND DIAGNOSTIC DATA

commands implement vendor-unique pages to test the drive during
the manufacturing process. It is recommended that initiators specify
only the non-page format variants of these commands (PF=0), except
for page 0x40.
