Hi Michael,

The Seagate ST336607LW has firmware: 0004.
Seagate have stated to me that this is the latest.
They have also stated to me:

Issuing an unrecognized or illegal command to the drive can cause the
drive to go into a hardware fault mode where it will no longer respond,
and may or may not respond to a SCSI BUS reset. It seems, in this case,
the drive will no longer respond to any commands issued by the
controller.

Is this "feature" now common on SCSI drives ????
