Hehe...  as someone who had to explain to a customer that 2500+ drives
needed replacing due to a manufacturing defect don't tell me anything about
"reliable enough"..  Those were FC drives by the way.

True, but CRC does not buy you much if the media are fubared enough to be
largely unreadable.

At least.  Have multiple copies of the same data.  Use different media
vendors for those copies.  Added bonus for using different media writer
drives.  Store under controlled conditions, esp temp &
moisture.  DVD & BR are basically consumer electronics stuff, so use ample
caution.
