If the medium has become poor as the result of a backup or device error, the data on it may be recoverable, but you may not want to risk writing to the tape again immediately.
What I have done is to create a pool for such media, and I move them into it for the duration of their protection. When protection has expired, reformat the medium - it might be helpful to assign it a label that indicates it has been reused (I add an * to the label, so LF1234L4 becomes LF1234L4*).
This works for both physical and virtual media.
