Alright, I won't jump... but I'm getting to that stage.
I ordered a TRIMARCHI R/W Optical Drive "Laserase" in February.
When I received it, it did not work properly
and I have spent the last 6 weeks swapping hardware boards,
and adjusting software with no luck.  It still operates
unreliably.  Besides being very sensitive to the power up
sequence, I can get it to operate and create a file system,
however during a large tar from tape to disk, I get a read
error each time.  I still am not sure I have the correct
SCSI flags in my entry in scsi_data.c for the kernal.
If anyone has this drive and knows which flags listed
below should be used, PLEASE mail me.  Also, if you use the
drive with no special device (RZxx, unknown on boot up), let
me know.  Thanks.  Also, what is the correct largest partition
that can be made on a platter?

	Which are correct?  		My system: DS3100 / Ultrix 4.1
		SCSI_TRYSYNC		(almost certainly NOT, causes
					 all sorts of errors in use!)
		SCSI_STARTUNIT
		SCSI_MODSEL_PF		recommended by Trimarchi
		SCSI_REQSNS		recommended by Trimarchi
		SCSI_NO_DBBR
		SCSI_NO_OPTTABLE
		SCSI_REMOVABLEDISK	recommended by Trimarchi
		SCSI_TESTUNITREADY
		SCSI_READCAPACITY

Thanks a a lot,
