What does HRESULT 0x80AA0A02 (E_IMAPI_RAW_IMAGE_SECTOR_TYPE_NOT_SUPPORTED) mean?

E_IMAPI_RAW_IMAGE_SECTOR_TYPE_NOT_SUPPORTED

E_IMAPI_RAW_IMAGE_SECTOR_TYPE_NOT_SUPPORTED means the raw image was asked to use a sector type outside the sector formats supported by IMAPI for this operation. IRawCDImageTrackInfo exposes the sector type of each track, and the IMAPI_CD_SECTOR_TYPE enumeration defines the CD sector representations understood by the API.

Verify sector framing before investigating the recorder

• Log the requested IMAPI_CD_SECTOR_TYPE value and the track whose stream is being added.
• Verify that the stream payload matches the chosen sector representation; do not label arbitrary blocks as audio or Mode 1 data.
• Keep image-creator sector validation separate from later IDiscFormat2RawCD device capability checks.

The failure occurs at raw-image construction semantics, so swapping media or reducing write speed is not a useful first response. Check the application mapping from source format to IMAPI sector type and confirm that the stream was prepared for that representation. If the recorder later rejects a data block type, that is a different E_IMAPI_DF2RAW_DATA_BLOCK_TYPE_NOT_SUPPORTED path tied to the device write format.
