Or if you don't try hard enough, you can't even prove the presence of errors.

Detailing the Spirit rover's problems. From:
http://www.cnn.com/2004/TECH/space/01/26/mars.rovers/index.html
"Trosper said the problem appeared to be that the rover's flash memory
couldn't handle the number of files it was storing. The jam-up, she
said, apparently kept Spirit from shutting down properly and performing
a number of functions that normally originated in its flash memory.
"Scientists are still analyzing the data, she said, but would begin
deleting unnecessary files to test that theory.
"She pointed out that the scientists had thoroughly tested the rover's
systems on Earth, but that the longest trial for the file system was
nine days, half of the 18 days Spirit operated before running into the
problem."

Perhaps this is the first time that a defrag actually fixes something?
