We were talking about data CDs  - I thought.

I suspect one couldn't even remotely be able to hear a
missing bit or two.

RS> If too much (or critical) data is missing, the

They aren't as far as I know. I had a MS Office CD that had
a pin hole so small that it escaped my notice for some time.
This CD would fail EVERY time the program installation was
attempted. o problem other than time getting it replaced.
