Re: dirty device

[Jim Langston <jimlangston@xxxxxxxxxxxxxxxx>]

Old tapes will cause this error I believe.  

Tapes stretch over time.  There are only so many times a tape can be written/
read from before they stretch out of usefulness.

We were getting cleaning errors at one time 'til I bought some new tapes and
retired the old ones.
