Maxtor ATLAS 10K IV User Manual page 69

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.
