These tape drives keep track of the number of defects it finds on a tape. If that number goes above a certain count, 20 I think, the tape is rejected. Also, the drives tries to read and/or write a header on the tape. If it can't the tape is rejected. Your best bet is to throw that tape away and get another. I used to have a box full of tapes that my 8mm drive rejected. I thought that I might be able to get them to work. Repeated degaussing never did the trick.
