This is a new drive? New tapes? You've got termination setup properly? Try seeing if you can write all zero's to the tape:
$ mt erase $ dd if=/dev/zero of=/dev/nsa0 bs=512k It should run for a while until it gets EOT. You're going to have to experiment with permutations of the following settings until your drive passes btape test: # Hardware End of File = no # Hardware End of Medium = no # BSF at EOM = yes # Backward Space Record = yes # Backward space File = yes # Forward Space Record = yes # Forward Space File = yes # Fast Forward Space File = yes # TWO EOF = yes ~BAS
