   If you want to see the full log, I can post it. I had a look just after   
   purchase, checking to see the disk was actually new.

   Yes, it is an air breather, I noticed the hole covered with some kind of   
   gauze or filter.   
      
   They could just fill with nitrogen, if helium is expensive.

   I guess. This is not a fridge sized disk, after all :-)
