Hello!
	Yes, it is me again, the guy who is having troubles
with his dumps.  I am using dd to verify that the writes to
the tape happened correctly.  Well, it seems that my troubles
are with dd, not with dump, and I'm confused.  From the
keyboard, I type

	prompt) dd if=/dev/rst1 of=/dev/null bs=1024

and this error msg appears on the console:

st1:     Error for command 'read', Error Level: 'Fatal'
        Block: 0        File Number: 0
        Sense Key: No Additional Sense
        Incorrect Length Indicator Set

What is a length indicator?  Is this something on the tape,
or is this an undocumented parameter of dd?  Any help would
be appreciated.  Oh, the details: this is an exebyte drive
on a sparcstation running SunOS 4.1.1.  There are multiple
files on the tape, I get this error msg no matter which
file I attempt to dd.  I have also tried *not* setting
a block size on the dd (i.e. letting it be the default).

Thanks for any help.
