[FIXED] How to Resolve Any Disk Read Error in Windows 10?

If you’ve encountered a disk read error occurred on your Windows 10 computer, you’re in the right place. In this guide, we will give you with step-by-step instructions and effective solutions to help you overcome this frustrating issue.

Whether you’re dealing with a boot disk error, a read disk error on an external drive, or any other disk-related problem, we’ve got you covered. 

Let’s dive in and get your Windows 10 system back up and running smoothly.

What is a Disk Read Error?

A disk read error happens when your computer can’t read the information stored on the hard drive or SSD. Basically, it means that the data on the disk cannot be accessed. 

When something goes wrong with the hard drive or a specific partition on it, your PC stops what it’s doing and shows you a message that says “a disk read error occurred.“

It even tells you to press Ctrl+Alt+Del to restart the computer. You should follow that advice and see if it fixes the issue right away.

If you’re lucky, the problem will be gone and you won’t have to worry about it happening again.

However, if you’re not so lucky (and if you’re reading this guide, chances are you’re not), the disk read error message will keep coming back after you restart the PC.

It might show up right away or after a few minutes. In that case, you’ll need to troubleshoot the problem to get rid of it for good.

Why Does the “Disk Read Error” Message Appear in Windows 10?

There are a few common reasons why you might see a disk read error. Let’s take a look at some of these causes:

• Loose or Faulty Cables: If the cables connecting important hardware like the hard drive are loose or damaged, it can make it difficult for your computer to read data from the drive.
• Damaged Hardware: If your hardware is damaged, it can lead to disk read errors. Physical defects in the system memory can also cause similar problems.
• Boot Sector Damage: The boot sector is responsible for starting up Windows when you turn on your computer. If the data related to the boot sector becomes damaged or corrupt, it can trigger a disk read error and prevent Windows from booting properly. 
• Memory Issues: Insufficient memory in your computer can cause a range of problems, including disk read errors. 

How to Fix Disk Read Errors in Windows 10

Before getting into the more energy and time consuming fixes, try running a malware scan on your PC. Certain viruses can cause disk errors on Windows.

Removing these threats might help solve the problem.

If no malware has been discovered on your PC, try these fixes:

Fix 1: Check cable connections

Inside your computer, there are different hardware components connected to each other with various power and data cables.

Sometimes, a loose or faulty cable can cause a disk read error, and it can be tricky to figure out which cable goes where.

• If you’re not comfortable checking the cables yourself, take your computer to a technician who can do it for you. 
• If you’re feeling adventurous, you can try it on your own.

Desktop PCs and laptops have similar hardware and cable setups, but there may be slight differences depending on the manufacturer.

It’s a good idea to read a tutorial specific to your computer model on how to open it up and reseat the cables. This will guide you and help you avoid any mistakes.

Once you access the cables, check if any of them have come loose. Look for any signs of damage, and if needed, replace them with new cables of the same type. 

Fix 2: Clean up your PC

Keeping your computer clean and tidy can help prevent disk read errors. Here are some simple steps to clean up your PC:

Uninstall unnecessary programs

• Open the Control Panel
• Go to Programs & Features.
• Uninstall any apps or programs that you no longer need. 

Declutter your desktop

• Delete any unnecessary files from your desktop. You can also arrange them in folders to make the desktop cleaner and free up RAM.

Fix 3: Check the system memory

Random Access Memory (RAM) can contribute to disk read errors in Windows 10. 

Here’s how: due to an improperly placed module or a computer case that lacks good ventilation, the RAM modules can get quite warm.

The more heat a RAM module emits, the more likely it is to partially move from its slot on the motherboard. This can cause a memory error alongside other types of issues.

Reseating the RAM modules can often solve disk read errors. 

You can also use the inbuilt Windows Diagnostics tool to check for problems with the installed memory:

• Open the Start menu and type Windows memory diagnostics.
• When the Windows Memory Diagnostics dialog shows up, select the option Restart now and check for problems.
• The PC will reboot into the memory diagnostics test screen. The process can take several minutes, so you may leave the PC and do something else with your time.
• A slowly increasing bar will show you the progress of the test. You will get an alert if any issues are detected.
• When the test is complete, Windows will boot to the desktop and display the test results.

If the test results aren’t displayed, you can find them yourself:

• Press the Windows logo + X keys at the same time and select Event Viewer from the menu.
• In the Event Viewer window, go to Windows Logs > System and click the Find option in the right pane.
• Type MemoryDiagnostic into the Find box and click Find Next. 
• The results of the memory diagnostics test will be shown at the bottom of the window.

Fix 4: Defragment your hard drive

Disk read errors are associated with hard drive problems. A hard drive can become so fragmented that reading data on it becomes a slow and cumbersome process.

In some cases, extreme fragmentation can lead to the inability to read the disk altogether, hence the error message.

The solution is to defragment the hard drive so the data can be accessed faster.
