Error Code error-lost-writebehind-data — Windows 11

Postup řešení

1. 1 First, try to safely reconnect the device. If it's an external drive, unplug it and plug it back into a different USB port. This can reset the connection and clear temporary glitches. If the error persists, proceed to the next step.
2. 2 Open Command Prompt as administrator. Press Windows key + X and select 'Terminal (Admin)' or 'Command Prompt (Admin)'. This gives you the necessary permissions to run disk repair tools.
3. 3 Run the CHKDSK command to check the drive for errors. Type 'chkdsk X: /f /r' (replace X with the drive letter) and press Enter. If the drive is in use, you'll be prompted to schedule it for the next restart. This command scans the drive for bad sectors and file system errors, which can cause write-behind failures.
4. 4 If the drive is external, ensure you use the 'Safely Remove Hardware' feature before unplugging. Right-click the drive in File Explorer and select 'Eject'. This ensures all cached data is flushed to the drive.
5. 5 Update the storage controller drivers. Press Windows key + X and select 'Device Manager'. Expand 'Disk drives' and 'Storage controllers', right-click each device, and select 'Update driver'. Outdated drivers can cause communication errors between Windows and the drive.
6. 6 If the error persists, disable write caching on the drive. Right-click the drive in File Explorer, select 'Properties', go to the 'Hardware' tab, select the drive, click 'Properties', then 'Change settings'. Under the 'Policies' tab, select 'Quick removal' instead of 'Better performance'. This prevents data from being cached, reducing the risk of loss.
