STATUS_HASH_NOT_SUPPORTED
The SMB server has disabled the requested content-hash mode
SMB content information retrieval can request a particular hash version and retrieval type. The server returns this status when hash generation is disabled globally, disabled for the share, or unsupported for the requested version and mode.
This is a server capability or policy result, not a checksum mismatch. Record the SRV_READ_HASH fields and the share involved. A client that uses hashes to optimize transfers must fall back to ordinary reads or another supported version without treating the file as corrupt.
What to inspect
- Capture hash version, retrieval type, offset, length, and share.
- Check server and share hash-generation policy.
- Use a documented fallback when content hashes are optional.
