Storage drives have their own life span. They fail, and their failure comes without any warning. You need to proactively & routinely check your Mac storage drive with its ingrained self-monitoring analysis & reporting technology (SMART), whose basic information can be accessed through macOS Disk Utility.

Checking & Repairing Mac Drive via Disk Utility

The process to fetch SMART status and fix any corruption issues with your Mac storage drive by using Disk Utility goes like this:

Step 1. Press Command + Space Bar keys to open Spotlight. Type ‘disk utility’ and hit Return.

Step 2. In the Disk Utility window, select the Mac hard drive or the SSD from the left pane.

Step 3. Look at the S.M.A.R.T. status on the right, and if it shows Verified, then the storage drive is not failing. Else you need to fix the issue.

Step 4. To repair your failing drive, click First Aid then click Run.

Step 5. If Disk Utility cannot fix the drive, then back up and erase the drive.

Mac Disk Utility Limitations

The above manual Disk Utility method to keep a tab on your storage drive is rather tedious and does not warn you against any imminent danger about the drive’s health. Even the SMART information fetched by Disk Utility is not comprehensive. You need more information such as read/write/seek error rate, reallocated/uncorrectable sector count, temperature, and other SMART details with associated status, worst value, threshold value, and fitness percentage.

Besides, it would be best if you had real-time monitoring of your Mac storage drive that warns you in case the drive’s Temperature, Performance, and Health deteriorates. You also require the facility to surface scan your storage drive to map its bad sectors/blocks.

Why live monitor your Mac storage drive?

Storage drive failure can wipe away your years’ worth of precious data. The data can be your treasured digital memory in the form of your family pictures, personal videos, sound recordings, and so forth. It can be your business critical documents whose timely unavailability can result in loss of money, business, and reputation.

Although the new generation of storagedrives—hard drive, solid-state drive, and embedded multimedia card (eMMC)—incorporate SMART, it is neither immuneto failures nor data loss. So, it is incumbent on you to monitor the internalor connected external storage drive of your Mac by using SMART. Also, deploy TimeMachine, the macOS backup app, to safeguard against any data loss situations.

On live monitoring your Mac storage drive, you can anticipate imminent drive failure and clone the drive to another external storage drive to protect your precious data.

Once you have cloned your failing drive, replace it with the clone drive. This way you can upkeep your storage drive.
