Corrupted external hard drives can be a frustrating problem, especially if you have important files stored on them. Fortunately, there are several ways to repair a corrupted external hard drive without formatting and losing your data. In this article, we’ll explore the most effective methods to get your drive back up and running.
Method 1: Repair Corrupted External Hard Drive with Windows Tools
Windows offers built-in tools that can help you repair a corrupted external hard drive without formatting. Here’s how to use them:
1. Open “This PC” and right-click the drive that has bad sectors. Select “Properties”.
2. Go to the “Tools” tab.
3. Click “Check” to check and repair the bad sectors on your hard disk.
4. If prompted, click “Yes” or enter the administrator password.
5. Click “Scan drive” and then “Repair drive”.
6. Wait for the process to finish. The scanning process may take a while depending on the size of your external hard disk and the specifications of your PC.
Method 2: Use the CHKDSK Command in Command Prompt
Another way to repair a corrupted external hard drive is by using the CHKDSK command in Command Prompt. Here’s how:
1. Press the Windows key R simultaneously, type “cmd”, and hit Enter.
2. Enter the command: “chkdsk E: /f /r /x” and hit Enter. (Replace E with your own drive letter)
3. The CHKDSK command will scan your drive for errors and attempt to fix them. Keep in mind that this process may cause data loss, so make sure to back up your important files first.
Method 3: Update Disk Driver in Device Manager
Sometimes, a corrupted external hard drive can be caused by a faulty or outdated disk driver. You can try updating the driver to see if it resolves the issue:
1. Right-click “This PC” and choose “Properties” > “Devices Manager”.
2. Click on “Disk drives”, right-click on your hard drive that is not showing up in Windows, and choose “Uninstall device”. (Make sure you have selected the correct USB device).
3. In the prompt asking you to confirm the removal, click “OK”.
4. Restart your computer and reconnect the drive to the PC. After the computer restarts, the driver will be automatically installed.
Method 4: Use Third-Party Software
If the above methods don’t work, you can try using third-party software to repair your corrupted external hard drive. One popular option is EaseUS Data Recovery Wizard, which offers a “Repair Corrupted/Damaged File System” feature that can help fix file system errors without formatting.
1. Download and install EaseUS Data Recovery Wizard.
2. Launch the software and select your corrupted external hard drive.
3. Click “Scan” to let the software analyze your drive for errors.
4. Once the scan is complete, click “Repair” to fix any file system errors.
5. If the repair is successful, you should be able to access your files again.
Remember, these methods may not always work, and in some cases, you may need to resort to formatting your drive. However, before doing so, make sure to back up your important files to avoid losing them permanently.
