Hi group,

after upgrading several packages with apt I have problems backing up data to
tape (DDS-3) with the "verify" option of tar (tar cvfW). After writing the
data, at the point where tar should rewind the tape and start the verify
pass, I get the message above.

Could it be the tape media that causes this error? Unfortunately, I have no
other media for testing. What can I do to get things verified?

Thanks a lot,
Magnus
