## Before you start: What you need to check your SSD health

Disk Utility is a built-in application on every Mac, so you don't need to download or install anything extra to check your SSD’s health. Before running any diagnostics or repairs, it’s essential to have a current backup of your data. This precaution protects you against unexpected data loss during the process.

When using Disk Utility to assess SSD health, you can view the SMART status—a basic indicator of drive reliability—and run First Aid scans that check for file system errors. The interface will show your SSD listed in the sidebar, with information such as the drive’s name and capacity, and status messages like “Verified” or warnings if problems are detected.

However, Disk Utility has limitations. It cannot provide detailed insights into SSD wear levels, such as the number of write cycles or precise error rates. For these advanced diagnostics, specialized third-party tools are necessary. Understanding what Disk Utility can and cannot reveal helps set realistic expectations for your SSD health check.

1. Open Finder and go to Applications > Utilities > Disk Utility. You should see your SSD listed on the left panel with its name and capacity.
2. Look below the drive’s name for the SMART status. It should say “Verified” if the drive is healthy or display a warning if issues exist.
3. Ensure you have a recent backup of your data using Time Machine or another backup method before proceeding with any repairs or scans.

## How to check SSD drive health in Disk Utility

To start assessing your SSD's health using Disk Utility, first open the application by navigating to **Applications > Utilities > Disk Utility**. Once opened, the left sidebar will display all connected storage devices, including physical drives and their volumes.

Next, identify your SSD by selecting the physical disk rather than its volumes. The physical disk typically appears at the top level with the drive's brand and size, while volumes are indented below. Selecting the correct physical SSD is essential because SMART status applies to the entire drive, not individual volumes.

With your SSD selected, look at the bottom or right side of the Disk Utility window for the **SMART Status** indicator. This status informs you if the drive's Self-Monitoring, Analysis, and Reporting Technology detects any issues. Common statuses include *Verified*, meaning the drive appears healthy, or *Failing*, signaling potential hardware problems.

If the status shows *Verified*, your SSD currently has no detected issues. However, if it indicates *Failing* or anything abnormal, consider backing up data immediately and planning for repair or replacement. Remember, Disk Utility’s SMART checks provide a basic health overview but may not catch all problems.

## How to check SSD disk health using First Aid in Disk Utility

First Aid in Disk Utility is a tool designed to verify and repair common disk errors. It checks the file system's integrity and attempts to fix issues that could affect your SSD’s performance or data stability. While it doesn’t assess the physical condition of the SSD’s hardware, running First Aid helps maintain the logical health of the drive.

1. Open Disk Utility from the Applications > Utilities folder. Once open, select your SSD from the sidebar. Make sure to select the physical drive, not just a volume within it.
2. Click the **First Aid** button in the toolbar. A prompt will appear asking if you want to run First Aid on the selected disk.
3. Click **Run** to start the process. Disk Utility will begin checking the disk for errors and attempt repairs automatically.
4. Wait for First Aid to complete. You will see messages indicating the progress and results, such as “Checking file system,” “Checking volume information,” and “Verifying catalog file.”
5. Review the report once the process finishes. It will show one of three typical outcomes:
- *Success:* No errors were found or repairs were needed. Your SSD’s file system is healthy.
- *Minor errors fixed:* Some issues were detected and repaired. It’s advisable to run First Aid again to confirm no further errors remain.
- *Failure to repair:* First Aid could not fix some problems. These might indicate more serious file system corruption or hardware issues requiring backup and further diagnostics or replacement.

Remember that First Aid focuses on software-level problems, so persistent errors despite repairs could point to underlying hardware faults. Use First Aid regularly as a preventive measure, but if problems persist, consider professional help or alternative diagnostic tools.

## How to check health of a SSD and HDD together in Disk Utility

If you have both SSD and HDD drives connected to your Mac, Disk Utility lets you check their health individually, but you can review them together in one place. Start by opening Disk Utility from Applications > Utilities. The sidebar lists all connected drives, showing their names along with the physical device type.

1. Select a drive in the sidebar. To identify whether it is an SSD or HDD, look under the drive name for a description like “Solid State” or “Rotational.” SSDs will be labeled as “Solid State,” while HDDs often show as “Rotational.”
2. Check the SMART status at the bottom of the Disk Utility window. This status is available for both SSD and HDD drives and indicates whether the drive reports any hardware issues.
3. Run First Aid on each drive by selecting the drive and clicking the “First Aid” button. This process checks and repairs logical file system errors for both SSDs and HDDs, but does not assess physical wear.
4. Repeat these steps for each drive you want to check. You can switch between drives easily in the sidebar to monitor all your storage devices.

Keep in mind that SSDs and HDDs show different early warning signs. SSDs often fail due to wear on memory cells, which SMART might detect as “Reallocated Sector Count” or “Program Fail Count.” HDDs typically indicate problems through increased bad sectors, slow read/write speeds, or unusual noises.

| Health Indicator  | SSD Signs                                                           | HDD Signs                                      |
| ----------------- | ------------------------------------------------------------------- | ---------------------------------------------- |
| SMART Status      | Pre-failure warnings like reallocated sectors, program/erase cycles | Reallocated sectors, spin-up time, seek errors |
| Physical Symptoms | Usually silent; failure from wear                                   | Clicking sounds, slow access times             |
| First Aid Effect  | Fixes file system errors, no physical repair                        | Fixes file system errors, no physical repair   |

Depending on the type and health of your drives, prioritize backing up data from failing or borderline drives. SSDs tend to fail suddenly once wear limits are reached, so regular backups are critical. HDD failures may offer slightly more warning but still require prompt data management. Using Disk Utility to monitor both types together helps you maintain awareness of your Mac’s overall storage health.

## Troubleshooting common issues when checking SSD health in Disk Utility

Sometimes, Disk Utility may not display the SMART status for your SSD, showing "Not Supported" or leaving the field blank. This often occurs with external drives or certain SSD models that don’t report SMART data. In this case, you won’t get detailed physical drive health info from Disk Utility, so consider using specialized third-party tools that offer deeper diagnostics.

![Troubleshooting common issues when checking SSD health in Disk Utility – how to check SSD health in Disk Utility](https://macfixly.com/content/images/2026/10/check-ssd-health-disk-utility-3.webp)

If you encounter errors during the First Aid process that cannot be repaired, such as "The underlying task reported failure" or "First Aid found corruption that needs to be repaired," it indicates logical issues beyond Disk Utility’s repair capabilities. You should immediately back up your data and then try running First Aid again in Recovery Mode by restarting your Mac while holding Command + R.

When Disk Utility reports your SSD as unmountable or inaccessible with messages like "The disk could not be mounted" or "Operation failed," it may suggest a serious file system problem or hardware fault. Again, prioritize backing up your data. If the drive remains unusable, try connecting it to another Mac or using a third-party recovery tool.

After these steps, if issues persist, contacting Apple Support or a trusted repair service is recommended. Reliable backup is the key before attempting any repairs or replacements.
