I get the same thing when trying to recover a file on uls, the server running networker and the exb-210 is attached to-

Looks like a simple I/O error due to cleaning or media problem.

Both of the files you tried to recover were on the same tape (uls-001), have you tried to recover another version of those files located on different tape ?

Thankyou so much to all of you for helping me overcome my Networker woes. Sanjay and I tried what Mitchell and Stefan suggested, we used device /dev/rmt/2cbn, ran an inventory, ran backups, and below is the proof that I was able to restore a file from the tape.
