Length
This field indicates the number of bytes in the page. However, this value
does not include bytes 0 and 1. The length is returned on MODE SENSE
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 device returns a CHECK CONDITION status with sense key set to
ILLEGAL REQUEST if it receivees 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.

bit is ignored.

specified by the contents of MRIE is selected. When this bit is set to 1, all
information exception conditions are disabled regardless of the contents
for the MRIE field. To enable CHECK CONDITION mode, DExcpt
should = 0. Default setting = 1.
