Hello Experts,
Today I found one of our NDMP backup failed with the error code 84 media write error.
I check the bptm logs at the time of the failure which are below :

However,
The backups are running fine on this drive after this failure. No error reported again.
I searched and found the best matching tech Note TECH59178
It states that it Requires tape drive hardware problem to be resolved.
Could this be the possible hardware prolem coming in sight?? please advise
