- Run the command diskutil list to see all drives in the system. Take note of the index of the desired drive to check the SMART attributes.
- Run the command: smartctl -a /dev/disk0
- Make sure to select the correct disk index when running the command. In the above example disk0 was used.
- Other variants of this command could be sudo /usr/local/sbin/smartctl -a /dev/disk0 or sudo smartctl -a /dev/disk0
The SMART attributes and other drive’s details will be displayed in the terminal screen.
Getting the SMART status from the MacOS* Graphical User Interface (GUI)
- Click the Apple icon in the menu bar.
- Click About This Mac in the drop-down menu.
- Click System Report in the pop-up window.
- Locate and select SATA/SATA Express in the hardware menu.
- Locate the SMART Status in the hard drive feature list. The status will read either Verified or Failing.
- If the status shows Verified the drive is working properly. If the status shows Failing then it may need to be replaced.
- The failing status can mean the SSD is faulty or files on the drive are corrupted.
