Hi, if I only had bought a plain ultra adapter... but they were sold out, so I chose the U2W. Unfortunately my very simple configuration with a single DAT Tape at the narrow connector simply refuses to work. ("timeout" in the log, "mt status" hangs) After some hours of experimentation I arrived at the latest software releases, very conservative parameters, but with no success. And -- strange enough -- it works fine with NT! May the solution is already there -- in the logs -- has anyone got an idea?
