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.

method specified by the contents of MRIE is selected. When this bit
= 1, all information exception operations are disabled and the
contents of the MRIE field are ignored. When in this mode, the
TapeAlert Log page is polled by the software. To enable CHECK
CONDITION mode, DExcpt should = 0. Default setting = 1.
