It's not a TOPS-20 thing. 9 track tapes write over whatever was there before
and unlike QIC tapes, leave no indication that reading should stop there.
A tape imaging program will read past the double EOF marks and pick up whatever
follows. Given that the dump fragment has a dump date of 1985, it is probably
left over from then. Talk to Tim and ask him what he used to create that directory
fragment, obviously it's capable to dealing with it.

afa the errors.. the tapes aren't clean reads. there are bad blocks and missing blocks.
