I have reason to believe that this drive contains a SCSI protocol bug.

I'm extending the scope of this message to current-users to enquire
about other Micropolissen of the same vintage (this one abviously has
a Sun stamp in it) that seem to behave strangely.

Meanwhile, try adding

       {{T_DIRECT, T_FIXED,
         "MICROP  ", "1588-15MBSUN0669", ""},     SDEV_AUTOSAVE},  

to the scsi_quirk_patterns[] table in scsi/scsiconf.c.
