ERROR_WRITE_FAULT
The write failed below the application layer
ERROR_WRITE_FAULT reports that the system could not complete a write to the target device. Possible causes include failing storage, controller or cable errors, device removal, firmware faults, filter-driver interference, or a network-backed device losing connectivity.
What to verify
- Check free space, but do not assume this code is equivalent to disk full.
- Review system event logs and device-health information.
- Confirm the target remained connected and writable for the whole operation.
- Preserve the original path, byte range, and lower-level status in diagnostics.
Application behavior
Treat uncertain writes carefully: the operation may have completed only partially. Flush and reopen only according to the API contract, validate file length or checksums, and avoid silently continuing with corrupted output. Repeated failures justify moving data to another device and investigating the hardware path.
