Google published a paper fairly recently on a large study of disk failures. As I recall, they
found that SMART logs were not reliable indicators.

Notice I said gradually degrading. SMART won't help in the event of a catastrophic mechanical
failure, which is what most of the unanticipated failures in the Google study probably were.
Fsck doesn't help in that case either though. It's only the kinds of failures that cause a
slow accumulation of bad sectors that fsck would matter for, and those are the kinds of
failures that SMART is piratically guaranteed to catch.
