And all media (including tapes, drives, and even RAM) will fail over
time.  Should I spend every minute of my life continuously verifying
everything I've ever stored?  Of course not.  At some point, you have to

has been a Free, reliable, ubiquitous, and convenient performer so I
recommend it with confidence.  And you happen to like BRU.  Hey, thats
cool.  I contend that neither is a wrong answer.
