NS_E_MEMSTORAGE_BAD_DATA
Practical scope of NS_E_MEMSTORAGE_BAD_DATA
This HRESULT is produced at reading the in-memory burn description or staged item data. This result belongs to cd/dvd recording and imapi state, not to an undifferentiated “Windows Media problem.”
Pipeline position
At the checkpoint, windows Media Player builds a burn playlist, refreshes its calculated status and delegates physical recording or erase work to the optical-disc stack; The recorder, inserted medium, burn format, staging files and write engine each have a separate lifecycle. The page-specific boundary is reading the in-memory burn description or staged item data.
A recorder that enumerates can still be busy, incompatible with the inserted medium or unable to sustain the selected write operation. In a typical failing run, stale or damaged in-memory staging metadata is reused after a failed session.
Reproduction record
| Evidence | Why it matters for memstorage bad data |
|---|---|
| Producing object and operation | recorder unique ID and exclusive-access owner, inserted media profile/state, burn format, playlist item, source locality, duration/byte estimate, staging directory free space, write speed, current IMAPI action and underlying HRESULT |
| Decisive observation | burn object generation, serialized playlist/staging data size, checksum/parse result and producer |
| Generation identity | Record the same disc, device, job or Player operation generation that returned this result; a reconnect or media change creates a different test. |
| Underlying result | Keep the first device, filesystem, COM, codec, DirectShow, IMAPI or BITS result seen before the Player mapped it to this result. |
| Controlled comparison | Repeat the producing call after changing only this condition: rebuild the burn playlist and staging data from known-good source items. |
Reading the evidence
| Observation | Interpretation |
|---|---|
| The recorded values match the boundary | The result is consistent with reading the in-memory burn description or staged item data; correct that state before changing unrelated codecs, drivers or playlists. |
| A lower layer failed before this result | Preserve that earlier HRESULT or device result because it may be only the Player-level mapping. |
| The same call passes after one isolated change | The comparison supports the memstorage bad data diagnosis rather than a broad installation failure. |
| The code changes after retesting it | The boundary was passed; diagnose the new HRESULT as the next independent stage. |
It scopes the failure to reading the in-memory burn description or staged item data.
Verification procedure
- Capture
0xC00D117B, it, the exact Player/API operation and the first timestamp at which it appears. - Save burn object generation, serialized playlist/staging data size, checksum/parse result and producer; do this before ejecting media, reconnecting a device, canceling a job or rebuilding the Player object.
- correlate the result with recorder unique ID and exclusive-access owner, inserted media profile/state, burn format, playlist item, source locality, duration/byte estimate, staging directory free space, write speed, current IMAPI action and underlying HRESULT.
- Reproduce once with the original source and destination, then apply only this change: rebuild the burn playlist and staging data from known-good source items.
- Create a fresh operation generation and verify that the original call advances beyond the memstorage bad data boundary.

NS_E_NO_CD_BURNER | enumerating an optical drive that reports burn capability to the Player |
Change the smallest responsible condition
The targeted action is to rebuild the burn playlist and staging data from known-good source items. While retesting it, keep unrelated media, device, playlist and network values unchanged.
When verifying it, do not repeatedly start a new burn against a drive that still owns or finalizes the previous session; Capture the media state and recorder owner before ejecting or replacing the disc.
