Logical Block Address
The Logical Block Address specifies the logical block where the write operation begins.
Transfer Length
The Transfer Length specifies the number of contiguous logical blocks of data to be transferred. For this
command, a transfer length of zero indicates that no data is to be transferred or written on the media. This
is not considered an error condition. Any other value indicates that number of logical blocks will be
transferred.
Disable Verify (DISVFY)
The Disable Verify (DISVFY) field will prevent a verify pass from being performed if set, otherwise a verify
pass will always be performed for a write command giving it the same functionality as the Write with Verify
command.
NOTE
Since there is no verify pass performed if this option is selected, the
unrecoverable read error rate specified in the Product Specification is
not supported.
If any of the following conditions occur, this command is terminated with a CHECK CONDITION status and
the Sense Key is set as indicated in Table 45. This table is not exhaustive.
