Disk Read Error on Your Computer

The disk read error is a common issue that many computer users face. It occurs when your computer is unable to read data from the hard drive, resulting in a failure to boot up. This error can be caused by various factors, including hardware failure, software issues, or corrupted files. However, it is a fixable problem that can be resolved with some troubleshooting steps.

Tips to Fix Disk Read Error on Your Computer

In this article, we will discuss how to fix the disk read error on your computer. Moreover, you can check these types of issues with computer repair specialists. 

1. Check the cables

The disk read error may occur due to loose or faulty cables. Check the cables connecting the hard drive to the motherboard and ensure that they are properly connected. If you find any loose or damaged cables, replace them immediately.

2. Change the boot order

Sometimes, the disk read error occurs because your computer is trying to boot from a non-bootable device, such as a USB flash drive or a CD. To fix this, you need to change the boot order. You can do this by accessing the BIOS settings on your computer. 

Restart your computer and press the appropriate key (usually F2 or Delete) to enter the BIOS setup. Navigate to the Boot tab and change the boot order to prioritize your hard drive. Save the changes and exit the BIOS setup. Your computer should now boot up normally.

3. Repair the Master Boot Record (MBR)

The Master Boot Record (MBR) is a crucial part of your computer’s startup process. If it gets corrupted, it can cause a disk read error. You can repair the MBR using the Windows installation disk or a system repair disk. 

Insert the disk into your computer and restart it. Press any key to boot from the disk when prompted. Choose the language and keyboard layout, then click on the Repair your computer option. 

Select Troubleshoot, then Advanced options, and finally, Command Prompt. Type “bootrec /fixmbr” and press Enter. This will repair the MBR and fix the disk read error.

4. Run CHKDSK utility

CHKDSK (Check Disk) is a utility built into Windows that checks for file system errors and bad sectors on your hard drive. It can fix errors that cause the disk read error. 

Open the Command Prompt by typing “cmd” in the search bar and selecting Run as administrator. Type “chkdsk c: /f /r” and press Enter. Replace “c:” with the drive letter of the hard drive you want to check. The utility will scan the drive and fix any errors it finds.

5. Replace the hard drive

If none of the above methods works, your hard drive may be damaged beyond repair. You may need to replace it with a new one. Before doing this, back up all your important files and data to an external hard drive or cloud storage. Remove the old hard drive and replace it with the new one. Install the operating system and all the necessary drivers.


A disk read error can be a frustrating problem that can prevent you from using your computer. However, with the above troubleshooting steps, you can fix the issue and get your computer running again. 

If you are not comfortable doing these steps on your own, you can take your computer to a local computer repair shop or a Macbook repair specialist to get it fixed.
