A hard drive's health can be checked in diskutil either in terminal, my choice, or in the desktop. I will provide the terminal version first and the desktop version in a web url below. . Following the terminal result is a statement of whaat the result means.
There is a diskutil command in terminal which checks the health of the hard drive. Copy this command and paste it into germinal, hit return: diskutil info disk0 | grep SMART If all is ok, voiceover willl say: SMART Status: Verified Here from the web page below is what that means: "SMART stands for Self Monitoring Analysis and Reporting Technology, and it's a way for a drive to report its health or problems to macOS. SMART status reports if a drive is failing and can tell you when there's a severe problem with the disk hardware" https://blog.macsales.com/45024-here-is-how-to-check-smart-status-of-your-mac-drives/ On Fri, 8 May 2020, 'Tim Kilburn' via MacVisionaries wrote: > Hi, > > Most of the time, HD health is not really ???testable???.
