Hi Arno, thanks for the infos. I found the following messages in /var/log/messages. Could this show a problem? I am not familiar with this Until now I have not worked with smartmontools. I have installed them and added the /dev/sg3 in the smartd.conf file. Let's see what happens. The Tapes I am using are new, also is the Library and all the cabels.
