There has been some time since I last use the DAT tape. When I try to write some data using star I get the following error: star: Invalid argument. Error writing '/dev/nst0' tar gives a similar error. /dev/st0 does not work either. However mt seems to work as usual. The kernel is 2.6.14-1.1656_FC4. Some time ago everything worked perfectly. -- Gérard Milmeister Langackerstrasse 49 CH-8057 Zürich
