Why Should You Test Your Mac’s Disks?

Having a well-performing hard disk drive (HDD) or solid-state drive (SSD) is a critical factor in the overall performance and functionality of your Mac or MacBook. A disk in poor health can result in slower system response time and can eventually lead to data loss. The worst-case scenario is that your drive fails completely and you cannot start your computer.

Testing your Mac’s disks regularly can give you an indication when the device is not performing optimally. You may also want to test the drive to determine the extent of damage or corruption if you start to experience issues like missing files. It is foolish to ignore any signs that your disk may be acting up. Failure to act quickly may lead to a data loss situation that could have been avoided with some preemptive actions.
