How to repair error code 0146 in Dell laptop and desktop? Read on to know the steps to fix error code 0146.
We’ve mentioned below some possible fixes that can help you fix hard drive error code 0146.
1. Run onboard diagnostics

4. Run System File Checker (SFC) scan
At times, drive corruption or an incompatible file system leads to error 0146. You can run the System File Checker scan to repair corrupt or missing system files and registry files. SFC is a tool from Windows that checks the integrity of system files.
Important – from Windows 8, Windows uses Deployment Image Servicing and Management or DISM. If you are using Windows 7, then skip this step and go on to SFC /Scannow.
Before you type SFC /Scannow type DISM.exe /Online /Cleanup-image /Restorehealth. It allows Windows to obtain the files needed for restoration.
Windows Update has to be functioning and not turned off for DISM to work.
To run SFC scan, follow these steps:
- Go to Start and type cmd. Press CTRL+SHIFT+ENTER.
- Type SFC /Scannow to run the SFC scan.
- After scanning, restart your system.
If SFC scan can’t replace system files, it asks for Windows installation DVD or media to repair corrupt or damaged system files.
