Apparently, the system always thinks it's at the beginning of the tape. 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.
