Page Length
This field indicates the number bytes in the page.
However, the value does not include bytes 0 and 1.
The length is returned in MODE SENSE commands
and must subsequently be set to the same value
when performing MODE SELECT. If the page
length does not match that expected by the drive, a
CHECK CONDITION status is returned, sense key
set to ILLEGAL REQUEST.
The drive returns a CHECK CONDITION status
with sense key set to ILLEGAL REQUEST if it
receives an unsupported Page Code or a Page field
with values not supported or changeable. In such
cases, no parameters are changed as a result of the
command.
