 Well, so far, so good.  The above is exactly what one would expect 
from a Binary transfer.

Now if you had included one of the blocks from the dump, we could 
have looked at it to see if the line-feed characters were in it, or if 
you had tried $SET FILE /ATT=RFM=STMLF TESTFILE.DONE 
and looked at a $DIRECTORY/FULL TESTFILE.DONE to see if 
that's what you wanted.  (You could also do the convert thing if you 
want to keep the old file and create a new one.)  I'm also not so sure 
that you don't want the customer to use ASCII transfer, which 
probably will not give fixed 512-byte blocks.
