Fix “Hard Disk I/O Device Error” Issue in Windows

Restart your computer

Before we start with I/O device bug fixes, there is one thing you should try first. Restart your system and then try again. A reset can fix a variety of errors without having to do anything complicated or time-consuming. If the I/O device error persists, proceed to the other fixes below.

Check your cables and connections

The first thing to do, before worrying, is to simply adjust the cables. Replace the cables that connect your external drive to your computer. Do this at both ends. If you’re using a USB flash drive, try unplugging it and reinserting it, then try again. If that doesn’t work, use another USB cable and try again. Not sure if the cable is good or not? Plug the cable into another external device and connect it to your system. If it works, you know the cable is good.

Try another USB port

Try another port if the USB cable works but unplugging the USB cable does not resolve the I/O device error. Most modern systems have more than one USB port, as many devices rely on a USB connection. Also check that your USB ports are clean. If it’s dusty or dirty, tap gently to remove stubborn lint, then try again.


Although I/O device errors are caused by hardware, we can try using an inbuilt system tool to fix the problem. The chkdsk tool checks file systems and fixes file system errors. Press Windows key + X to open the quick access menu, then select Command Prompt (Admin). If the Command Prompt option is no longer there (replaced by PowerShell), don’t worry. Simply search the Start menu for Command Prompt, then right-click and select Run as administrator.

Then type chkdsk /f /r /x and press Enter. The scan may take some time, especially if there are many areas that require repair. If CHKDSK returns no errors, you can proceed to Windows System File Check (SFC), another built-in system tool. But, before running the SFC command, it is important to check that it is working properly. To do this, we use the Deployment Image Servicing and Management tool, or DISM. Like SFC, DISM is a built-in Windows utility with a wide range of features. In this case, the DISM Restorehealth command ensures that our next solution works properly. Perform the following steps.

  • Type Command Prompt (Admin) in the Start menu search bar. Next, right-click and select Run as administrator to open an elevated command prompt.
  • Type the following command and press Enter: DISM /online /cleanup-image /restorehealth
  • Wait for the command to complete. The process may take up to 20 minutes, depending on the state of your system. The process seems stuck at times, but wait for it to complete.
  • When the process is complete, type sfc /scannow and press Enter.

Update device driver

Another option to resolve a disk I/O error is to update the device driver. Windows 10 should update all your drivers all the time. Sometimes conductors pass through the net.

Enter device manager in the Start menu search bar and select Best match. Device Manager contains information about all devices on your computer. From here you can update individual drivers for specific hardware. In this case, you can update your storage device driver, resolving the disk I/O error.

  • Select Drives to display options. Right-click the drive with the I/O device error and select Update Drivers.
  • Select Search automatically for updated driver software. The process will start checking for driver updates both online and offline.
  • If an update is available, install it and then restart your system.

Change your drive letter

A quick fix for the I/O drive error is to change the drive letter of the storage hardware. If Windows fails to assign a drive letter for some reason, disk I/O error is one of the errors you may encounter. You can use the computer management system tool to assign a new drive letter to the drive.

  • Enter computer management in the Start menu search bar and select the best match.
  • Go to Storage > Disk Management in the left column.
  • Right-click the drive with the Disk I/O error and select Change Drive Letter and Paths > Change.
  • Assign a new drive letter using the drop-down list, then press OK.

Use Speccy to check drive health

If the two simple solutions don’t work, we can check the overall health of the hard drive using the free system spec program, Speccy. In the left column, select Storage and scroll down to find the corresponding drive. They are usually well labeled. Scroll down to the SMART Reader Specifications table. SMART stands for Self-Monitoring, Analysis and Reporting Technology. The built-in hard drive monitoring system reports various hard drive health attributes. As you can see, Speccy assigns a score to each monitoring metric. The following metrics should be checked:

  • 05: Number of reallocated sectors
  • 0A: number of rotation attempts
  • C4: number of reassignment events
  • C5: Current number of pending sectors
  • C6: number of uncorrectable sectors

Do you want an amazing fact? A Google study found that within 60 days of the first uncorrectable drive failure, the drive was on average 39 times more likely to fail than a similar error-free drive.
