On Windows

Visit https://crystalmark.info using a web browser. On your regular web browser, visit the CrystalMark website to see the SSD health check application.

Click CrystalDiskInfo Standard Edition . This is the first option below the "Quick Download" heading. You will be redirected to the download page and the process will start automatically. If the file doesn't download automatically, click the blue "CrystalDiskInfo7_5_2.exe" link in the middle of the page.

Open the installation file. Double-click the file you just downloaded to start the installation program. The full file name will be "CrystalDiskInfo7_5_2.exe".

Downloaded files are usually located in the "Downloads" folder by default.

Click YES to allow the installation file to make changes to your computer when prompted.

Select "I accept the agreement," then click Next . If you want, you can read the license agreement and then click the radio button next to "I accept the agreement". Click "Next" when you are ready to continue.

Click Next . CrystalDiskInfo will begin installing into the default directory shown in the text field. If you want to change the installation location, you can click Browse and select a different folder.

Click Next . A folder will be created in the Start menu. You can change the default name in the text field if you want to rename this folder in the Start menu.

You can also click the "Don't create a Start Menu folder" check box if you do not want to add the folder to the Start menu.

Check or uncheck the "Create desktop shortcut" box and click Next . The shortcut icon will be created on the desktop. If you do not want to create a shortcut on the desktop, you can uncheck the box above and click "Next".

Click Install . The installation will begin and last no more than a minute.

Launch CrystalDiskInfo. Once the CrystalDiskInfo installation is complete, make sure the "Launch CrystalDiskInfo" box is checked, then click Finish to launch the application. If not, you can double-click the application shortcut on the desktop or in the software installation folder.

Select the drive. All drives installed on the computer will be listed above the application. Click on the SSD under the "Health Status" heading whose health you want to check and evaluate. Good ratings will display as "Good" along with a health percentage, with a maximum of 100%.

If the health status is "Caution" it means the SSD is likely damaged in some areas, the drive is old and may be defective.

Click Continue . If you are running First Aid on a startup disk, the startup sound will temporarily freeze, and other applications will not respond until the process completes.

Click Show Details . A report of problems (if any) detected on the drive will appear. A message with red text indicates a problem with the drive. The final message will tell you whether the SSD needs to be repaired or not.
