Troubleshooting Error Code 45 on Disk Partition: Your Simple Guide

Step 1: Utilize Windows Troubleshooters

Windows comes with built-in troubleshooters designed to automatically fix common issues, including Error Code 45. Depending on your OS version, the procedure may differ.

For those using a version later than Windows 10 build 1809 :

1. Search for Windows PowerShell and select it.
2. Choose Run as administrator.
3. Type msdt.exe -id DeviceDiagnostic to initiate the Hardware and Devices Troubleshooter.
4. Click Next and follow on-screen instructions to complete the process.

After the troubleshooting, please reboot your system and check if the issue is resolved.

If your OS is prior to Windows 10 build 1809, proceed with these steps:

1. Press Windows + R, type control panel, and hit Enter.
2. Select Troubleshooting.
3. Click on Hardware and Sound.
4. Choose Hardware and Devices, then click Next to run the troubleshooter.

Follow the instructions displayed on your screen, and reboot your PC upon completion.

Step 2: Update the Device Driver

Updating your device drivers is essential for optimal hardware functionality and preventing conflicts. Here’s how:

1. Press Windows + X and select Device Manager.
2. Locate the device associated with the error, right-click it, and select Update driver.
3. Choose Search automatically for drivers and follow the prompts.

Once updated, restart your computer and see if the error is resolved.

Step 3: Execute the System File Checker

The System File Checker (SFC) scans for and repairs corrupted or missing system files that may impede device connectivity.

1. Press the Windows key, type cmd, and hit Enter.
2. Select Run as administrator. Confirm any prompts.
3. Input sfc /scannow and hit Enter.

Once the scan is completed, exit Command Prompt and reconnect your device to verify functionality.

Step 4: Conduct a DISM Scan

The Deployment Imaging Service and Management Tool (DISM) helps to correct issues within the system image that SFC may not be able to tackle.

1. Open cmd by searching it and then selecting Run as administrator.
2. Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.

Wait for the operation to finalize.

Step 5: Uninstall and Reinstall the Drivers

If the above updates do not rectify the issue, consider uninstalling and then reinstalling the device driver.

1. Access Device Manager by pressing Windows + X.
2. Right-click the affected device, choose Uninstall device, and confirm.
3. Reboot your computer. Windows will reinstall the driver automatically.

Step 6: Run CHKDSK Utility

The Check Disk (CHKDSK) utility checks the disk for errors and can fix issues that may be causing the hardware connection problems.

1. Open cmd and select Run as administrator.
2. Input chkdsk.exe /f /r and press Enter.
3. If prompted, type Y to schedule the scan at the next startup.

After scheduling, restart your computer to allow CHKDSK to complete its operation.

If troubleshooting proves ineffective, consider replacing the defective hardware component.
