E_IMAPI_DF2DATA_CLIENT_NAME_IS_NOT_VALID
E_IMAPI_DF2DATA_CLIENT_NAME_IS_NOT_VALID reports invalid client identification on the data-format object. IDiscFormat2Data::put_ClientName sets the friendly name used by the IMAPI client, and the value must be accepted before the write workflow proceeds.
Validate client identity at object setup time
- Log the exact string passed to
put_ClientName, including whether it is empty. - Set the client name once during format-object initialization rather than deriving it from changing image metadata.
- Do not retry the write until the client-name setter itself succeeds.
This HRESULT is not a filesystem volume-label or disc-title error. Those names belong to image or filesystem metadata; ClientName identifies the application using the recorder. Replacing the disc or rebuilding the data stream cannot fix an invalid client string. Keep the client-name setup result separate in logs so a later write failure is not incorrectly blamed on media.
