When trying to write a tape, amanda says:

INFO taper tape genepi000 kb 0 fm 0 writing filemark: Input/output error

Is there a way to test to see if this really is a bad tape?  It's a
VXA-2 and they are usually pretty reliable.  I'm worried about what
happens when it comes around in my rotation again, should I
re-label it and see if that fixes it?  Will that mess up my
rotation?

Thanks,
  Steve
