S.M.A.R.T.
The old drive in my Mac Pro has a S.M.A.R.T. status of ‘failed’. Should I move it to a different drive slot?
Does a ‘bitmap error’ mean that my hard disk is about to fail?
There is now a better way to estimate likely hard disk life than Mean Time Between Failures (MTBF).
The real world performance of S.M.A.R.T. to warn of imminent drive failure is not as impressive as its claims, but here is how to get better use from it.
