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

that expected by the drive, a CHECK CONDITION status is returned,

sense key set to ILLEGAL REQUEST.

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.

EER Enable Early Recovery. Set to 1 (always enabled).

PER Post Error. Default is 0. When set to 1, this bit enables reporting of

Check Condition to report recovered READ / WRITE errors.

before declaring an unrecoverable error.
