5 Amazing Apps to Check Your Mac Hard Drive Health

Last updated: Jul. 24, 2017

Mac health check

Hard drives fail, they eventually will. It doesn't matter if your Mac is with a spinning hard disk drive (HDD) or a solid-state drive (SSD). Data shows that 22% of hard drives fail in their first four years.

Is there anything we can do to extend a hard drive's life? There are plenty of. But, you never know when your Mac hard drive will fail or crash; And if that happens, it can be a disaster for the data you've saved in the drive.

So, what can you do to prevent it?

Two things! Number one: check the drive health, and number two: backup the data on a regular basis. It may sound simple, but implementation is usually complex.

For data backup, we recommend Time Machine (the built-in Apple tool already exists on your Mac), and if you can, use a Mac drive clone software in the meanwhile. This is optional, but it's more efficient to restore data if needed.

Today, we're going to show you 5 great tools to check Mac hard drive health, from speed test, disk verify and repair, to disk cleaning and tuneup, we cover them all.

1. Disk Utility

The first thing to do is check S.M.A.R.T. Status. SMART (Self-Monitoring Analysis and Reporting Technology) is an internal monitoring system that is included in almost all Mac hard drives (HDDs and SSDs).

S.M.A.R.T helps you get a basic idea of the health of your Mac drive. How to identify? Open Disk Utility. Highlight the hard disk name on the left, then check the status from the table (see below). If it shows "Verified", that means your hard drive is not failing. Otherwise, you may need to replace it right away. If your budget allows, consider upgrading to an SSD.

Next, check disk errors with First Aid. If your Mac is with OS X El Capitan or latest macOS Sierra, just select Macintosh HD on the left and click on First Aid. A new window will pop up asking you if you would like to run, just hit Run to continue. Note: For OS X Yosemite or older versions, use the two buttons on the right corner "Verify Disk" and "Repair Disk" instead.

2. CleanMyMac

MacPaw CleanMyMac is a Mac cleaner app that helps make more room on your full hard drive. It does a number of things to deep clean your Mac system and free up as much space as possible. In addition, you can use it to fix broken preference files, find duplicates, remove unnecessary extensions, and uninstall third-party apps on Mac.

In short, if your Mac hard drive is getting full, you won't go wrong using CleanMyMac to free up more disk space.

3. Blackmagic Disk Speed Test

If you feel your Mac hard drive is slow to respond, probably it's time to test its write/read speed. You'll find Blackmagic amazing. It's a simple to use app that allows you to quickly benchmark and certify your Mac hard drive performance.

After installing the application on your Mac, open the app and click the START button in the center. Soon you'll see the numbers shown on two speedometer circles.

Note: it's best to quit all other apps before using this app, this helps get more accurate data.

4. Stellar Drive Defrag

Get Stellar Drive Defrag (Now Part of Drive Toolbox)

If your Mac is with a hard disk drive (HDD), you'll find this app helpful as it can search for all scattered pieces of large data files on your disk, group and store them in contiguous segments. The procedure helps improve data access speed and overall Mac hard drive performance. What's cool about the app is that it adopts intuitive color legend which enables you to immediately identify whether your Mac needs defragging.

5. CleanMyDrive

CleanMyDrive is another useful app and it's free. In fact, the app is more like a lightweight drive manager for both internal Macintosh drive and external drives. You can use it to check your hard drive status, e.g. a visual look of how your drive is used, how many junk files exist. If it detects hidden junks, you can use the app to clean them automatically. It also works with USB flash drives, SD memory cards, etc.
