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.
Perf Performance bit. Not supported, always = 0.
