(Solved) How to resolve any Disk read error in Windows 10?

A hard disk is a key part of the computer that is under heavy load (reading and writing almost continuously). It contains your operating system, your software, your data, in short, it is essential in computing.

Unfortunately, it can happen that your hard drive encounters problems that can manifest themselves by slowing down your computer, crashes, or untimely restarts.

However, since Windows has a built-in test tool, it can warn you of any inconvenience if there is an error with your hard drive or partition. Among the many types of warnings, one of the most frightening is “A disk read error has occurred”. If this error has happened to you, you’ve come to the right place: we offer useful solutions to solve this problem.

What’s a disc read error?

A disk read error is a common situation; it usually occurs as soon as your computer boots from an SSD, HDD, or other hard drive and has affected a large number of Windows 10/8/7/XP users.

This error displays the message “A disk read error has occurred. Press Ctrl+Alt+Delete to restart.”

Simply put, a disk error may be caused by several reasons such as incorrect boot order, BIOS problem, IDE cable failure, incorrect MBR configuration, defective hard disk, etc. The following are some of the reasons why disk errors may occur.

When you face such a problem, no matter how many times you restart your computer by pressing “Ctrl+Alt+Del” keys, this error will persist. In fact, a disk reading error is not a problem that can be solved by a simple reboot. But don’t worry, this post will give you some useful solutions to this disk error problem.

How to resolve the disc read error?

Exploring potential solutions for the common reasons for this error could help locate and solve the problem.

RAM Testing

A startup problem could be caused by the computer’s memory. You can use Windows Memory Diagnostic by typing in the Windows search bar and press “Enter”. This tool will work automatically when you restart the computer. And you can also try third-party software to test the available memory.

Replace RAM

Replace the RAM or if your PC system has two RAM modules, try to change their slots. In addition, clean all of the dust from the chips when you check it in case dirt gets in the way.

Check the cables

Lost connection or faulty cables could cause problems with startup and also hard disk drive errors. Therefore, find the disconnected cables. If possible, replace the cables with replacement parts. At the very least, disconnect them, check the cables for damage, and then replace them properly.

Test the hard disk

This means removing the hard drive from your current computer and connecting it to a working computer, where you can scan bad or defective sectors. This may help you determine if the problem is fixable or if you need a new hard drive and a new Windows installation.

Reconfigure the BIOS

It is this little piece of software that allows your computer to perform essential functions such as starting up the machine or detecting the various components connected to your motherboard, such as the graphics card, your keyboard, or your mouse. Resetting the BIOS to the default settings may resolve the disk read error. Access the BIOS from the Start menu and look for an option to load the default BIOS settings, which could be one of the options below or similar options :

  • Load BIOS default settings
  • Load default settings
  • Load the default safe mode

In addition, to download the latest available version of BIOS, you must use the best driver updater software. This type of software will allow you to reconfigure the Bios in a snap by getting the latest available update.

Defragment the computer

In some circumstances, this could solve the problem. The computer’s hard disk is divided into sectors, and it is the role of the OS to bring them together to form blocks (also called clusters). But the more a computer is used, the more the writing of files to the hard disk tends to scatter all over the storage space. It then takes longer to access the files, because the system has to scan the entire hard drive to rebuild the sets of elements. Deleting files or running software in the background also contributes to this fragmentation phenomenon, which slows down the PC. However, connect the hard drive to another device to start defragmentation and then try to boot from it.

Rebuild the Boot Configuration Data

The Boot Configuration Data is a Windows Server 2008 file that controls the boot configuration and how the operating system boots when you turn on your Windows computer. Occasionally, you may encounter problems with BCD that require you to rebuild the file. So, when you can’t start your computer and see a disk read error, Boot Configuration Data (BCD) would be corrupted or misconfigured. Rebuilding the BCD could be the solution.

Recovering data

It can happen that data is lost in case of disk read error or during unfortunate formatting! It is often still possible to recover data using data recovery utilities. However, data recovery solutions are not 100% safe, so it is better to choose the right tools! These solutions do not exempt you from making your own regular backups, quite the contrary!


That’s all folks! Here are a few ways to deal with how to resolve any disk read error in Windows 10. The solutions could be multiple but we have only mentioned a few. So, don’t hesitate to share your opinion in the comments section below.
