Try retensioning the tape--I find that with Travan tapes you have to
retension them pretty frequently, especially if they've been sitting
around for a few days since you last used them. I usually retension the
tape each time I use it. The command is usually:
mt -f /dev/your-tape-dev retension
I haven't found the Travan-4 tapes to be particularly reliable. Every
so often I find that I have to "erase" the tapes to get them working
again properly. I overwrite the whole tape with files of random noise
and then restore some of the files and check the checksums to make sure
the tape is still working properly.
