Once the hard drive is replaced, then all the data that was on your Mac’s sick hard drive can be restored from a recent backup. Yellow and Red are bad, your hard drive is reporting some problems and the hard drive should be replaced since it is either failing already or will likely fail soon. Green is good, your hard drive is not showing any problems. Within OS X Utilities, choose Reinstall OS X. Finally, the information module lets you see different data regarding the device's hardware and users. Prepare a clean external drive (at least 10 GB of storage). Onyx's records allows you to access dozens of reports generated by Mac which detail all the tasks that have been carried out, as well as all the possible errors that may have occurred. The report summary is a green, yellow or red button in the lower right corner. The following method allows you to download Mac OS X Lion, Mountain Lion, and Mavericks. Open it and SMARTUtility will read the SMART logs and give you a report within about 20 seconds. Download SMARTUtility, which requires Mac OS X 10.5 or higher. If it reports a problem, then I know that Apple will likely concur and will replace the hard drive. Thus, if a client reports problems with their Mac that make me suspect the internal hard drive might be failing, I will encourage them to run the demo version of SMARTUtility.

It’s important to note that most external hard drives do not include SMART technology. Onyx and SMARTUtility rely on this monitoring system to help you to check on your hard drive’s health. This feature is called S.M.A.R.T., which stands for Self-Monitoring, Analysis and Reporting Technology. Since the early 2000s most internal hard drives have been equipped with a feature that lets them monitor their own health and tries to predict failures. I recommend two applications for this purpose: Onyx (free) and SMARTUtility (free trial, then $25). It’s also prudent to periodically check the health of your Mac’s internal hard drive. Every hard drive will eventually fail. This is why it’s so important to backup your Mac’s hard drive. Hard drives are the component of a computer that fail most often.
