Just to be sure I get this right, can you please confirm that 0x57444300
for Write Inhibit DCB would result in the following CDB (to get 0x1000
bytes)?

"AD 00 57 44 43 00 00 30 10 00 00 00"

I just want to confirm byte ordering.  Thanks!

Henry,
Sorry about the omission.  You should also consult the references listed
in
the sub-clause on DCBs.

The Content Descriptor is 57444300h (ASCII "WDC" followed by a byte of
00h).

Regards,
Bill McFerrin

The MMC4r03 specification describes the format of a couple of the DVD+RW
Disc Control Blocks.  In particular, the Write Inhibit DCB is described
in section 16.27.2.19.2 on page 340, and the Session DCB is described in
section 16.27.2.19.3 on page 341.  However, it seems that the identifier
required to retrieve these DCBs (placed in the "Address" field of the
CDB) is missing from the specification.

Can this ommision please be fixed for the next release of the MMC draft
specification?  Also, if possible, please post these missing values in
the response (so we needn't wait for the next draft).

Thanks,
.
