I have been running successful backups for months now, but suddenly one of my tapes will not load. When I put it in the drive it reads for a moment and then ejects. Now last night we lost power for a while and when I came in to load today's tape, I am getting the same issue. I have 5 tapes one for each day of the week. 3 are working no problem, but two will automatically eject. Any Ideas?
