E_IMAPI_DF2RAW_MEDIA_IS_NOT_SUPPORTED
E_IMAPI_DF2RAW_MEDIA_IS_NOT_SUPPORTED means the medium in the selected recorder is not accepted by IDiscFormat2RawCD. The interface is a DAO-96 raw-CD writer; Microsoft documents the write path for blank CD media and exposes physical-media information through the format object.
Check the recorder and inserted medium as separate constraints
- Record the recorder identity and
CurrentPhysicalMediaTypeimmediately before preparation. - Verify format support for the recorder, then verify media support for the inserted disc.
- Do not treat DVD or BD capacity as sufficient evidence that a raw CD DAO operation is supported.
This differs from E_IMAPI_DF2RAW_MEDIA_IS_NOT_BLANK: a medium can be the wrong type even if unused, while a supported CD medium can fail because it is already recorded. Stream conversion also cannot change media compatibility. Preflight recorder and media support before building a large raw image so the failure is reported before expensive preparation work.
