			to return to a known position such as BOT.

			command and retry the failing command.

		4.	Prompt the user to back up the data to a new
			cartridge and discard the old one.
		5.	Log the incident in the system log.
50 00	Write append error	A write-type command failed because the point at which
		to append data was unreadable. This was probably
		caused by a powerfail, or SCSI bus or Fibre Channel link

		operation properly and appending an EOD.
	Action:	1.	Terminate the current I/O and return the appropriate
			error.
		2.	Tell the user that the append point is unreadable
