NS_E_REDBOOK_ENABLED_WHILE_COPYING
Failure boundary and ownership
NS_E_REDBOOK_ENABLED_WHILE_COPYING with value 0xC00D0FB0 records detecting a mismatch between the Player read mode and the drive’s Red Book setting. The producing call and its state are more diagnostic than a later aggregate Player failure.
Underlying mechanism
At the checkpoint, windows Media Player identifies the inserted medium, reads its table of contents, creates a CD reader, and then chooses digital audio extraction or an analog playback path; Ripping adds destination-path creation and an encoder selected from the user’s rip settings. The page-specific boundary is detecting a mismatch between the Player read mode and the drive’s Red Book setting.
Recognition of the drive does not prove that usable audio sectors, a stable digital-read path or a valid rip destination are available. The condition can be reproduced when Device Manager exposes analog Red Book playback while the Player attempts digital extraction.
Trace fields worth keeping
| Evidence | Why it matters for redbook enabled while copying |
|---|---|
| Producing object and operation | physical drive identifier, media-change generation, disc and track number, table-of-contents result, digital/analog mode, error-correction flag, read speed, rip state, output format and first lower-level drive error |
| Decisive observation | Player digital/analog choice, Device Manager digital-audio setting and active CD reader mode |
| 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: make the operating-system and Player drive settings agree before restarting the rip. |
What the comparison proves
| Observation | Interpretation |
|---|---|
| The recorded values match the boundary | The result is consistent with detecting a mismatch between the Player read mode and the drive’s Red Book setting; 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 this result may be only the Player-level mapping. |
| The same call passes after one isolated change | The comparison supports the redbook enabled while copying 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 detecting a mismatch between the Player read mode and the drive’s Red Book setting.
Decision path
- Capture
0xC00D0FB0, it, the exact Player/API operation and the first timestamp at which it appears. - Save Player digital/analog choice, Device Manager digital-audio setting and active CD reader mode; do this before ejecting media, reconnecting a device, canceling a job or rebuilding the Player object.
- correlate the result with physical drive identifier, media-change generation, disc and track number, table-of-contents result, digital/analog mode, error-correction flag, read speed, rip state, output format and first lower-level drive error.
- Reproduce once with the original source and destination, then apply only this change: make the operating-system and Player drive settings agree before restarting the rip.
- Create a fresh operation generation and verify that the original call advances beyond the redbook enabled while copying boundary.

Safe correction
Correct this boundary by making sure you make the operating-system and Player drive settings agree before restarting the rip. Then reacquire the interface or media state that produced it and repeat that call.
When verifying it, do not polish the disc, change the driver, switch read modes and change the rip format in one test; preserve the first failing track and alter one boundary at a time.
