This error occurs when the Windows operating system detects a controller error on a non-existent disk, causing the computer to lock up and preventing the opening of new programs or windows. The error is often accompanied by a message indicating that the driver detected an issue with the hard disk drive (HDD) or solid-state drive (SSD). This issue can be frustrating for users who rely on their computers for daily tasks.

The presence of this error in the Windows Event Viewer logs suggests that the problem may be related to a misconfigured disk or a faulty driver. However, since network drives are not physical disks, it is unlikely that moving files to a network drive is the root cause of the issue.

💡 Why You Are Getting This Error

  • The primary reason for this error is a misconfiguration of the disk drivers in Windows. This can occur due to various reasons such as outdated or corrupted drivers, incorrect disk settings, or a faulty BIOS configuration. In some cases, the driver may be trying to access a non-existent disk, causing the error.
  • Another possible cause is a hardware issue with the hard drive or solid-state drive (SSD). A faulty or failing disk can cause the driver to detect an error and prevent the computer from functioning properly.

✅ Best Solutions to Fix It

Disable and Re-enable Disk Drivers

  1. Step 1: Press the Windows key + R to open the Run dialog box, type 'devmgmt.msc' and press Enter. This will open the Device Manager.
  2. Step 2: In the Device Manager, locate the Disk Controllers section and expand it. Look for the disk drivers related to Harddisk3 or Harddisk4 and right-click on them to select 'Disable device'.
  3. Step 3: Repeat step 2 for each disk driver related to Harddisk3 or Harddisk4. This will disable the drivers temporarily.
  4. Step 4: Restart your computer and wait for it to boot up completely. This will allow Windows to reload the disk drivers.
  5. Step 5: Once your computer is booted, go back to the Device Manager and enable the disk drivers by right-clicking on them and selecting 'Enable device'.

Check Disk Configuration and BIOS Settings

  1. Step 1: Open the Disk Management console (Press Win + R and type 'diskmgmt.msc') to verify that there are no extra disks or disk configurations that may be causing the issue.
  2. Step 2: Check the BIOS settings of your computer to ensure that the disk configuration is set correctly. You can do this by pressing F2 during boot-up, selecting 'Advanced' and then 'Boot Order', and verifying that the correct disk is set as the primary drive.

✨ Wrapping Up

To resolve this issue, try disabling and re-enabling the disk drivers or checking your disk configuration and BIOS settings. If the problem persists, consider seeking further assistance from a professional technician or Windows support team.
