Solution 3. How to Repair Corrupted Hard Disk Using CMD

When a hard drive's file system gets corrupt and you can't access the hard disk, you can run a CHKDSK scan to repair the corrupt hard drive without formatting it.

The CHKDSK command checks the file system and the file system metadata of a volume for logical and physical errors. If used without parameters, CHKDSK displays only the volume's status and does not fix any errors. When used with the /f, /r, /x, or /b parameters, it fixes errors on the volume.

To give you some brief info, the “/f” parameter in CHKDSK fixes any errors that are found. The "/r" parameter asks the command to locate bad sectors on the drive. The “/x” parameter forces the drive to dismount before the process starts.

Step 1. Next to the Windows Start menu, in the "Search Windows" box, type cmd.

Step 2. In the search results, right-click on the "Command Prompt" and select "Run as administrator".

Step 3. Type the command: chkdsk E: /f /r /x in the Command Prompt window and press Enter. In the command, replace E with your drive letter.

Bonus Tips: How to Prevent Hard Drive Corruption Effectively

Repairing a hard drive is a difficult task, even for the experts. A couple of ways to protect your hard drive from corruption are by safely removing external drives before unplugging and making a regular backup.

To do the latter, you can use a tool like EaseUS backup and recovery software. It helps back up important data from your hard drives. To use this tool:

Step 1. For the first time you use EaseUS Todo Backup to back up files, click Create backup on the home screen and then mouse click the big question mark to select backup contents.

Step 2. Since you're going to back up files and folders on your computer, go on with the "File" backup mode, where you can select pictures, videos, documents and all other types of files to back up.

Step 3. Follow the paths to locate the files, folders or directories you want to back up, select them all and click "OK".

Step 4. Now you need to select a backup location to save and retain the backup.

Step 5. EaseUS Todo Backup allows users to save the backup files to every device that is handy for you, like a local hard drive, external USB drive, SD card, network drive, or a NAS drive, plus a cloud drive of the EaseUS brand. We personally recommend users to choose the cloud drive prior to a physical drive to save important backups due to the greater accessibility, flexibility and safety.

To be able to access to EaseUS cloud, all you need is an email registration and login. 

Step 6. If you're interested in an automatic and intelligent backup schedule for the next file backup task, go on with the "Options" setting.
