SCSI normally reports 3 things when it encounters an error (particularly
disk errors): Sense Key (SK), Additional Sense Code (ASC), and
Additional Sense Code Qualifier (ASCQ).

What appears in the below screenshot is a large amount of sense data,
but I can't make heads or tails out of it, because it's written in a
driver-centric manner ("Encl PD" means nothing to me).  I can read part
of the CDB data, but it doesn't tell me much.  Scott Long might know.

You should try asking the system manufacturer if they know what any
of the data means.
