Field Name Description
PS Parameters Savable. For MODE SELECT, this bit
must be 0.
Additional
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.

Maximum
Burst Size
This value specifies the maximum amount of data
that will be transferred without disconnecting. A
value of 0 sets no limit. Any value is in units of 512
bytes. For example, a value of 8 represents 4 Kbytes.
Values that are not multiples of 8 are rounded up to
the closest multiple of 8.
