Safe next steps
- For 19 (ERROR_WRITE_PROTECT), check whether the target media or volume is intentionally read-only, write-protected or locked by policy.
- Use the drive or device maker’s supported instructions and confirm you selected the correct destination before changing its write state.
- If the device unexpectedly became read-only or holds needed files, preserve data and investigate its health first.
After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.
