NS_E_CD_READ_ERROR_NO_CORRECTION
Where this result occurs in the Player workflow
NS_E_CD_READ_ERROR_NO_CORRECTION (0xC00D0FAB) marks reading an audio sector while error correction is disabled. For NS_E_CD_READ_ERROR_NO_CORRECTION, preserve that boundary even when the visible Player message is broader than the producing operation.
Mechanism
At the NS_E_CD_READ_ERROR_NO_CORRECTION 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 reading an audio sector while error correction is disabled.
For NS_E_CD_READ_ERROR_NO_CORRECTION, recognition of the drive does not prove that usable audio sectors, a stable digital-read path or a valid rip destination are available. A representative way to reach this result is that one track contains marginal sectors that fail on the first uncorrected read.
State snapshot
| Evidence | Why it matters for read error no correction |
|---|---|
| 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 | disc/track and sector position, correction flag, retry count and device sense or read error |
| Generation identity | Record the same disc, device, job or Player operation generation that returned NS_E_CD_READ_ERROR_NO_CORRECTION; 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 NS_E_CD_READ_ERROR_NO_CORRECTION. |
| Controlled comparison | Repeat the producing call after changing only this condition: enable correction for a controlled retry or replace the unreadable source disc. |
How to interpret the next test
| Observation | Interpretation |
|---|---|
| The recorded values match the boundary | The result is consistent with reading an audio sector while error correction is disabled; correct that state before changing unrelated codecs, drivers or playlists. |
A lower layer failed before NS_E_CD_READ_ERROR_NO_CORRECTION | Preserve that earlier HRESULT or device result because NS_E_CD_READ_ERROR_NO_CORRECTION may be only the Player-level mapping. |
| The same call passes after one isolated change | The comparison supports the read error no correction diagnosis rather than a broad installation failure. |
The code changes after retesting NS_E_CD_READ_ERROR_NO_CORRECTION | The NS_E_CD_READ_ERROR_NO_CORRECTION boundary was passed; diagnose the new HRESULT as the next independent stage. |
NS_E_CD_READ_ERROR_NO_CORRECTION scopes the failure to reading an audio sector while error correction is disabled. The presence of NS_E_CD_READ_ERROR_NO_CORRECTION does not establish a system-wide media failure; verify its owning operation before changing unrelated Player components.
Controlled diagnostic sequence
- Capture
0xC00D0FAB,NS_E_CD_READ_ERROR_NO_CORRECTION, the exact Player/API operation and the first timestamp at which it appears. - Save disc/track and sector position, correction flag, retry count and device sense or read error; do this before ejecting media, reconnecting a device, canceling a job or rebuilding the Player object.
- For
NS_E_CD_READ_ERROR_NO_CORRECTION, 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: enable correction for a controlled retry or replace the unreadable source disc.
- Create a fresh operation generation and verify that the original call advances beyond the read error no correction boundary.

NS_E_CD_SLOW_COPY | feeding the rip pipeline while another activity consumes drive bandwidth |
Focused correction
For this occurrence, enable correction for a controlled retry or replace the unreadable source disc. Recreate only the object that produced NS_E_CD_READ_ERROR_NO_CORRECTION and repeat the original operation against the same controlled input.
When verifying NS_E_CD_READ_ERROR_NO_CORRECTION, 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.
