S.M.A.R.T (Self-Monitoring, Analysis, and Reporting Technology) is used to test a Hard drives reliability and to determine if it is failing.
We are going to use CrystalDiskInfo to view your hard drive's S.M.A.R.T. data and see if the hard drive is developing issues.
Download CrystalDiskInfo here. When you reach the website you want to click the download link shown in the image below.
Now you want to select the link show below.
After the download is complete unzip the zip file. I'm using WinRAR to complete this action.
Now click open the folder you have unzipped and click DiskInfo as shown in the image below.
Now that CrystalDiskInfo is open we can check the drives
You can select different drives (image below)
If you see this its time to back-up and get a new drive (image below)
