Moving parts tend to go first, so when breakage occurs it’s likely to be a hard disk drive. The most important moving is the disk drive. If it moves, it can break. After that, it’s the fan. If that breaks, the hard disk drive may not be far behind.
How do you know when a Mac’s disk drive is about to die?
SMARTReporter is an inexpensive Mac app that monitors your Macs disk drives and gives you a warning when wonky is about to happen. Sometimes. Built into most spinning hard disk drives these days is the S.M.A.R.T. reporting system. It’s a self-monitoring analysis and reporting technology.
Think of it as an early warning system for disks that might be thinking about kicking the bucket, buying the farm, pushing up daisies, biting the dust, cashing in the chips, counting worms, giving up the ghost, or meeting the digital maker.
How SMARTReporter works is simple enough. It just checks the Mac’s hard disk drive every so often (you control the frequency) for a status report. If all is good, nothing happens.
If the report isn’t good, you’ll get a notification from SMARTReporter, and hopefully, enough time to make a good backup before the hard disk drive goes belly up.
The Status page of SMARTReporter is simple and easily understood and configurations are straightforward and nearly self explanatory.
The SMARTReporter warning icon resides in the Mac’s Menubar.
You control a few appearance and behavior options, too, including icon color, checking frequency, and how it notifies you of a changed status.
Does SMARTReporter always work?
No. Not always. Mostly. But not always.
My experience has been about two out of three hard disk drives going bad will give some kind of S.M.A.R.T. warning. Which means one out of three disks will die without much warning.
Yes. Not all hard disk drives are SMART smart, though most– but not all– newer SSDs found in MacBooks, MacBook Pro and other Macs are supported. Is it worth the few dollars to get another layer of warning that a component might be failing? Yes.
Today’s Macs do not have as many moving parts as in years past, but fans are everywhere, as are heat sensors, so if you want still another layer of potential protection make sure to check out Macs Fan Control. What does it do? It controls fans on your Mac.
