	Warning: If you use formats with more tracks than supported by
       your drive, you may cause it mechanical damage.  Trying once if
       more tracks than the usual 40/80 are sup- ported should not
       damage it, but no warranty is given for that.  Don't create
       device entries for those formats to prevent their usage if you
       are not sure.
