And now find that _both_ tape drives are producing the same errors

The Python 28454 has mostly been writing tapes (backups) since I
borrowed it, and has only been used to restore a few files in that
time, so its possible that it has always had this problem - though
I've not seen it.  Certainly it has read this same tape ok while
attached to a Sun at work.

I'll file a PR.
