When you try to access a corrupted hard drive, it shows an error message, “You need to format the disk in drive: before you can use it.”

The most common symptoms of a corrupted hard drive.

Try the following solutions to fix corrupted hard drive:

Fix 1: Run Antivirus Scan on your Hard Disk

  • Press Windows + I to open System Settings and then navigate to Update & Security > Windows Security.
  • Now, click Virus & threat protection on the right panel.
  • The tool will scan the device. If it detects any virus, you’ll see it in the scan results.
  • Follow the further instructions given on the screen (if any) to fix the issues with the hard disk. Then, reboot your system and see if you can access the hard disk now.
