Any advice on how can I diagnose this problem further?
Your controllers send data slower, so that should make for less errors. I can't believe that is the problem. Failed to write tape mark happens at the start and end of each backup. These demark the backup sessions. I remember something about writing a tape mark, backing up over it, and then going forward again reading the tapemark. If it can't find the tapemark, it assumes it was not able to write it. Its really that it couldn't read it. Things that caused that (back in the day when I was using tape) were: tape leaders of wrong type/lenght (or leaders when the drive didn't want any, worn out first portion of the tape (it gets more wear), improper erase, tape mark from an incompitable drive unexpectedly encountered. (in those days we really couldn't use the same tapes on different models of drives - maybe that is fixed these days).
