The Initialization Pattern option specifies that the logical blocks on the drive medium
will contain a specified initialization pattern. The Initialization Pattern descriptor is
sent to the drive as part of the FORMAT UNIT parameter list. Table 5-19 describes
the Initialization Pattern descriptors. The contents of the descriptor fields are described
in Table 5-20 and the types in Table 5-21.

NOTES:
1 If the Initialization Pattern Length is not 0, the drive terminates the command with
CHECK CONDITION status. The sense key is set to ILLEGAL REQUEST, and
the additional sense code is set to INVALID FIELD IN PARAMETER LIST.
2 If the Initialization Pattern Length is 0, the drive terminates the command with
CHECK CONDITION status. The sense key is set to ILLEGAL REQUEST, and
the additional sense code is set to INVALID FIELD IN PARAMETER LIST.
3 If the Initialization Pattern Type is not 0 or 1, the drive terminates the command
with a CHECK CONDITION status. The Sense Key is set to ILLEGAL REQUEST,
and the Additional Sense Code is set to INVALID FIELD IN PARAMETER LIST.
  
The Initialization Pattern Modifier must be 0.
The Initialization Pattern Type field (Table 5-21) indicates the type of pattern
the drive uses to initialize each logical sector within the initiator-accessible
portion of the medium. All bytes within a logical sector are written with the
initialization pattern.
The Initialization Pattern Length field indicates the number of bytes contained
in the Initialization Pattern. The valid lengths (when IP Type = 1) are two or
four bytes.
