 The Maxtor drive in question does not have the short Index pulse that is
 required by the EESDI controller.  The customer needs to contact Maxtor to
 find out how to get the short Index Pulse feature installed on their drive.
 (It may require an added jumper or an component and wire adds depending
 upon the level of the drive electronics card.)
