How to Check Disk Health on Mac with smartctl
There are various ways to check the health of a hard disk drive (HDD) and solid state drive (SSD) that is used on a Mac with drives that support SMART, which stands for Self-Monitoring Analysis Reporting Technology. These options range from fairly simple using Disk Utility to check the SMART status of a drive, to much more complex with third party tools like DriveDX.
We’re going to introduce another excellent option for Mac users to monitor and analyze the health of their storage devices, using a command line tool called “smartctl”.
The smartctl utility will check SMART status self-assessments of drive health, provide the temperature of internal drives, as well as offer read and write information (which is relevant particularly for SSDs), and general drive health analysis.
