The MODE SELECT command immediately checks the current page for invalid
parameters or invalid combinations of parameters before executing. If such an
exception is found, the drive returns a Check Condition status byte with an Illegal
Request sense key.
If the initiator does not set the Page Length field of the Mode Page to the value
indicated in the Mode Page definition (for example, 0Eh for the Device Configuration
Page, 01h for the Read/Write Error Recovery Page, and so forth), the drive
terminates the MODE SELECT command and returns a Check Condition status
bytes with an Illegal Request sense key. The Additional Sense Code and Additional
Sense Code Qualifier are set to Invalid Field in Parameter List.
