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.

Step 4. Select and check both "Automatically fix file system errors" and "Scan for and attempt recovery of back sectors", then click "Start".

• To run this tool in read-only mode, click "Start".
• To repair errors without scanning the volume for bad sectors, select the "Automatically fix file system errors" checkbox and click "Start".
• To repair errors, locate bad sectors, and recover readable information, click "Scan for and attempt recovery of bad sectors" and click "Start".

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.

3. Run SFC Scan

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.

Wait for the scan to finish and then restart the system. Try and see if you can access your hard drive.
