Re: 03-307r2, SBC, 32 Byte Commands for End-to-End Data Protection
Jim,
I would like ask that you consider defining additional 32-byte data
integrity commands in 03-307 as follows:
WRITE AND VERIFY (32) with BYTCHK option
WRITE SAME (32)
VERIFY (32) with BYTCHK option
I feel that the inclusion of the BYTCHK option is especially important.
The end-to-end protection mechanism can be used to ensure that the data
made it intact from point A to point B, but does nothing to ensure
persistency. The byte check option is an existing mechanism that can be
used to validate persistency.
Keith
