If you’re seeing the error code 0x8007045d on your Windows 11 device, it usually means there’s a problem with reading or writing data. This error can happen during file transfers, updates, or when accessing external drives.

Don’t worry—this guide will walk you through simple and effective steps to fix this error. You don’t need to be a tech expert; all instructions are explained clearly and in an easy-to-follow way.

By following these solutions, you can quickly get your system back to normal without losing data. Let’s start with some quick checks before diving into the fixes.

Keep your patience—sometimes the solution is just a few clicks away.

Quick Note: Prerequisites and Initial Checks

  • Check your cables and connections: If you are using an external hard drive or USB device, make sure the cables are securely connected and not damaged.
  • Restart your computer: Sometimes a simple restart can clear temporary glitches causing the error.
  • Ensure enough disk space: Lack of free space can cause read/write errors. Check your disk space in File Explorer.
  • Run Windows Update: Make sure your system is up to date, as some fixes are included in updates.

Step 1: Run the Windows Troubleshooter for Hardware and Devices

Windows has built-in troubleshooters that can find and fix common problems automatically. Here’s how to use it:

  1. Press Win + I to open Settings.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Hardware and Devices and click Run.
  4. Wait for the troubleshooter to scan your system and follow any instructions it gives.

This tool helps identify issues with connected devices and can fix minor driver or hardware-related problems causing the error.

Step 2: Check and Repair Disk Errors Using CHKDSK

The error code often relates to disk problems. Running the CHKDSK (Check Disk) utility can find and fix disk errors:

  1. Click the Start button, type cmd in the search bar.
  2. Right-click Command Prompt and select Run as administrator.
  3. In the Command Prompt window, type the following command and press Enter:
chkdsk C: /f /r /x

Explanation of the command:

  • C: refers to the drive letter you want to check. Replace it if your issue is with another drive.
  • /f fixes errors on the disk.
  • /r locates bad sectors and recovers readable information.
  • /x forces the drive to dismount before the process starts.

You may be asked to schedule the disk check on the next restart. Type Y and restart your computer. This process may take time, but it’s important to complete it fully.

Step 3: Update or Reinstall Device Drivers

Outdated or corrupted drivers can cause error 0x8007045d, especially when working with external devices. Updating or reinstalling drivers may help:

  1. Press Win + X and select Device Manager.
  2. Locate the device causing the issue (for example, Disk drives or USB controllers).
  3. Right-click the device and select Update driver.
  4. Choose Search automatically for drivers and follow prompts.
  5. If updating doesn’t help, right-click the device and select Uninstall device. Then restart your PC to reinstall the driver automatically.

Updating drivers ensures they communicate correctly with Windows, preventing errors like 0x8007045d.

Step 4: Use System File Checker (SFC) and DISM to Repair System Files

Corrupted system files can also cause this error. The System File Checker (SFC) and Deployment Image Servicing and Management (DISM) tools scan and repair system files:

  1. Open Command Prompt as administrator (like in Step 2).
  2. Type the following command and press Enter:
sfc /scannow

This will scan all protected system files and replace corrupted files with cached copies. Wait for it to complete.

  1. If the problem persists, run the DISM tool by entering these commands one after another:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

These commands check and repair the Windows image. Running them can fix deeper issues that SFC might not resolve.

Step 5: Format the Problematic Drive (Data Backup Required)

If the error occurs while accessing an external drive or USB stick, formatting the drive can fix file system errors. Warning: Formatting deletes all data on the drive, so backup important files first.

  1. Open File Explorer and right-click the problematic drive.
  2. Select Format.
  3. Choose the file system (usually NTFS for Windows) and uncheck Quick Format if you want a thorough format.
  4. Click Start and wait for the process to finish.

Formatting resets the drive’s file system and can resolve error 0x8007045d if caused by corrupted data structures.

Alternative Method: Use Third-Party Disk Repair Tools

If Windows tools don’t fix the error, you can try third-party disk repair software like EaseUS Partition Master, MiniTool Partition Wizard, or HDD Regenerator. These tools offer advanced repair options that may recover damaged sectors or files.

Always download such software from official websites and back up your data before using them.
