I was simply saying be wary of the problems with recent LTO microcode releases. You might inadvertingly break something while try to fix a completely different problem. I spoke too soon in my last message. After further testing, the latest code 1550 seems to have fixed my performance problems.

I presume that the volume suffering the error was the input to the Reclaim. As such, it would be a tape which was not written recently and thus was subject to different conditions than current tapes, which are not encountering like errors. Perhaps way back then the drive was in between cleanings and residue had built up on the head; or perhaps the drive had been having problems back then. Your service records, coupled with Activity Log records as to the drive that wrote the tape, may provide further insight. Perhaps the tapes were recorded under a different drive microcode level? I would keep records of tapes which exhibited such errors and, after they re-enter service (post reclamation), see if they show any further problems, which would tend to indicate a true media problem.
