I can read tapes just fine, however. Here are the vitals, followed by the results of trying to backup /var with both tar and dump. The kernel was fresh this morning (about 8AM EST). moran is a 200MH PPro with 64MB RAM. softupdate enabled on all partitions. I tried "mt erase" also; it ran for a while (the tape drive was active the whole time) and didn't complain about anything, but I still couldn't write the tape. ...
