Ok... somehow I got the impression that you could fsf' over the 
damaged files... which seems to be obvious as you say you fond that 
later tape files are ok.

Ok, for me to really understand what happens we need to go back to the 
shell :-)

When you load that tape, you can fsf to, say, file 21, and the tape 
drive reports the correct position.

But when, with the tape freshly loaded, you read to the end of file 
four, you can't fsf and more, not even fsf'ing 17 files to end up 
beyond the damaged area.

Is that a correct description?
