These are just a few problems I've experienced with my SCSI Tapes.

1) Using an ExaByte 8200 on a 2.1 system with an  Adaptec 1522A and
a 1542CF SCSI Card -
	
The dump application exits with the error 
		"st1: bad request, must be between 0 and 0"
when using a 8mm video tape. Granted, I should be using data quality
tapes but for non-critical backups I don't really have a problem with
using them. (They work o.k. with SunOS 4, BSD/OS and Linux).

2) Using an ARCHIVE Python 28454-XXX 4ASB on a 2.1 system with an Adaptec
2940 SCSI Card -

a) Occationally while doing backups the kernel reports 
		"/kernel: st0(ahc0:4:0): Target Busy"

b) After a dump I always need to execute "mt -f /dev/st0 offline"
in order to eject the tape. I am unable to eject the tape using the eject 
button.

	Thought I'd pass the information along.
