IMAPI_E_STASHFILE_OPEN_FAILURE

IMAPI_E_STASHFILE_OPEN_FAILURE comes from IMAPI2FS staging storage. The IFileSystemImage working directory is where stash files are built, and staging may be used explicitly or enforced by IMAPI for source files whose accessibility or throughput is unsuitable for direct burning. This HRESULT means the temporary backing file could not be opened or initialized.

Inspect the working directory and staging context

Record WorkingDirectory, the process identity, and free space on the volume.
Check directory existence, create/write permissions, security software interference, and file-system availability.
Record whether StageFiles was enabled or IMAPI had reason to stage unstable or removable sources.

The optical recorder is not the first component to investigate here. The failure occurs while preparing local temporary image data. A different recorder or lower write speed will not repair a working-directory open failure. Verify that the temp location is stable and writable for the entire build, and avoid cleaners or concurrent jobs that remove IMAPI staging files while the image object is active.
