Drive Health Warning: Drive Is Set to Read Only/Reliability Is Degraded/Spare Capacity Is Low
When you receive error messages like the drive is set to read only, reliability is degraded, and more, it typically indicates that your SSD or HDD is failing, or some functions of the storage device are limited. To put it more directly, there may be a large number of bad blocks or bad sectors in the disk and its life is about to end.
When this type of drive health warning shows up, what should you do? Follow the instructions below.
What Should You Do When You Receive Drive Health Warning in Windows Settings
Action 1. Back up Files Immediately
Since the drive health warning indicates that the disk may get damaged at any time, the first step is to back up all important data immediately to prevent data loss or damage. If you are still able to access the disk and edit the files, you can copy and paste the significant files to an external disk directly.
If there are a large number of files on your disk, you can use professional data backup software to make a file backup, and MiniTool ShadowMaker is the greatest one. It can help back up files, folders, partitions, and the entire disk easily and freely.
