We're running SCO Unix 3.2.2 with a 40 M Irwin tape drive. I
consistently run into cpio problems restoring from more than one tape.
Note that this does *not* occur when using sysadmsh to do the backup,
but when I try to do it freehand, I run into problems. The method to
date has been:

	find / -print | cpio -ovcB >>/dev/rctmini

	When restoring, I use:
	
	cpio -ivcdB </dev/rctmini

	but always hit a tape read error at the end of the first tape
and can't pick up on my second or third.

	Is it possible I'm just running out of tape too soon (I have
the default at 37 M on an allegedly 40 M tape), or is it something
else?
