How to Fix Error Code 0xC000005A

  1. Check Physical Write-Protect Switch

  3. Check Disk Properties in Windows

If the error persists after trying all steps, the storage device may be physically failing or the drive controller is damaged. In such cases, data recovery services should be considered if data is critical, or replace the hardware.

Frequently Asked Questions

What does error code 0xC000005A mean?
It means the media (USB, SD card, or hard drive) is write-protected, preventing any changes to the data. This can be due to a physical switch, disk attributes, or system policies.
Can error 0xC000005A damage my files?
No, the error itself does not damage files; it only prevents writing. However, underlying issues like file system corruption can cause data loss if not resolved.
How do I remove write protection from a USB drive?
First, check the physical switch. If that's not the issue, use DiskPart (attributes disk clear readonly) or modify the registry key StorageDevicePolicies.
Why does my SD card show write-protected without a switch?
Some SD cards have no physical switch; the write protection can be due to file system errors, a corrupted firmware, or the card being locked by a device. Try formatting the card (after backing up data) or using DiskPart.
Is this error common on Windows 10/11?
Yes, it can occur on any Windows version, usually due to a hardware switch or software write protection settings.
