Solution Steps
- 1 First, run a disk check to scan for file system errors. Open Command Prompt as administrator (Windows key + X → 'Terminal (Admin)') and type 'chkdsk C: /f /r' (replace C: with your system drive). You'll be prompted to schedule it for the next restart. This checks for bad sectors and repairs file system errors.
- 2 Update your storage drivers. Press Windows key + X and select 'Device Manager'. Expand 'Disk drives', right-click your hard drive, and select 'Update driver'. Choose 'Search automatically for drivers'. Outdated drivers can cause storage exceptions.
- 3 Run the System File Checker to repair corrupted system files. Press Windows key + R, type 'sfc /scannow', and press Enter. This can fix issues in the storage stack.
- 4 If the error persists, check the health of your hard drive using 'wmic diskdrive get status' in Command Prompt. If it shows 'Error', your drive may be failing, and you should back up data and consider replacing it.
- 5 Check for Windows updates: Press Windows key + I, go to 'Windows Update', and click 'Check for updates'. Install any pending updates, as they may include storage driver fixes.
