If your hard drive gets corrupted due to a file system error or the hard drive turns RAW, don't panic. This guide will provide you with detailed steps to repair a corrupt hard disk without losing data. To do this, you must first check if it is the logical error that prevents you from accessing the hard drive. If so, you can check and perform hard disk repair. If it is a physical hard drive problem, you'll need to send your hard drive to the data recovery or repair service center. 

Possible Causes of Hard Drive Disk Errors 

Before you try to repair the hard disk, you should know the reasons that cause hard drive corruption. Here is the list of top reasons for hard disk failure:

  • Virus attack
  • Bad sectors
  • Sudden system shutdown or crash
  • Human errors
  • Power supply and overheating problem

Now that you know what causes hard drive failure, you can repair the hard drive to solve your problem.

When you connect a RAW hard disk to your computer, Windows may display a prompt to format the corrupt (RAW) drive volume. Click "Cancel". Do not click "Format" as it will result in permanent data loss without a data recovery tool.

How to Perform Hard Disk Repair with Free HDD Repair Software

Before you start, you should manually check your power supply and the heat of your fan. Make sure that they are working properly. Only then, follow the following solutions for HDD repair:

1. Run Antivirus

Connect the hard drive to another Windows PC and use a reliable antivirus to scan the drive. Sometimes, viruses and malware can cause such errors. Therefore, an antivirus scan may repair the corrupted hard drive and make the drive accessible.

2. Check and Repair Hard Disk Error in Windows 10/8/7 

Try a Windows built-in tool first to check and repair hard disk errors. If it works, you can access your data. Here's how to do it in Windows 10, 8, or 7:

Step 1. Open "This PC/Computer", right-click the hard disk or partition which you want to check, and click "Properties".

Step 2. Select "Tools" and click "Check now" under Error-checking.

Step 3. Check Disk Options dialog will show up. Select any one of the options to check and repair the hard disk.

After the full repair process, your hard disk or hard drive partition should work normally. You can then try to access the saved data on the hard drive.

The SFC Scannow option is one of the several specific switches available in the SFC command. It helps fix the damaged or missing Windows system files that may cause drive corruption.

Step 1. Open a command prompt window. 

Step 2. Type sfc /scannow in the command prompt window and press "Enter" on the keyboard.

If the drive is a portable drive, type SFC /SCANNOW /OFFBOOTDIR=c:\ /OFFWINDIR=c:\windows and replace letter c: with your hard drive letter.
