E_IMAPI_UNEXPECTED_RESPONSE_FROM_DEVICE
E_IMAPI_UNEXPECTED_RESPONSE_FROM_DEVICE is a write-stage device failure. Microsoft describes the returned error information as something IMAPI could not recover from. It is broader than loss of streaming and should be correlated with recorder/media state and any preceding sense or command diagnostics.
Preserve the first device error around the failed write
- Record recorder model/revision, media type, current write speed, and write progress position.
- Keep any earlier sense-data status or media readiness error in chronological order.
- Test known compatible media and another recorder when the failure is reproducible, rather than repeatedly burning the same disc.
Because the error occurs in the write pipeline, the disc can be left incomplete or unusable. Do not automatically resume from the same assumptions about blankness or free sectors; re-query media state before another attempt. If the same image writes successfully on another drive, compare recorder/firmware behavior. If failure follows the same media, suspect media condition or compatibility.
