NS_E_PDA_NO_LONGER_AVAILABLE
Practical scope of NS_E_PDA_NO_LONGER_AVAILABLE
This HRESULT is produced at using a device or storage object that disappeared after enumeration. This result belongs to portable-device discovery, storage and capabilities, not to an undifferentiated “Windows Media problem.”
Pipeline position
At the checkpoint, windows Media Device Manager brokers between the Player, a device service provider and MTP, mass-storage or legacy device transports; Enumeration, Plug and Play identity, storage availability, format support and individual file operations are distinct checks. The page-specific boundary is using a device or storage object that disappeared after enumeration.
A device shown in Explorer can still disappear from the Player’s WMDM session or reject a media format, filename, directory operation or storage request. In a typical failing run, the device resets during a transfer and returns with a new object generation.
Reproduction record
| Evidence | Why it matters for no longer available |
|---|---|
| Producing object and operation | PnP instance and interface path, WMDM service-provider CLSID, device/partnership ID, connection generation, storage object and capacity, format-support result, firmware version, operation callback and first device or transport HRESULT |
| Decisive observation | device ID, last notification, connection generation and failing object pointer |
| 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: discard stale interfaces and re-enumerate if the device is still connected. |
Reading the evidence
| Observation | Interpretation |
|---|---|
| The recorded values match the boundary | The result is consistent with using a device or storage object that disappeared after enumeration; 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 no longer available 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 using a device or storage object that disappeared after enumeration.
Verification procedure
- Capture
0xC00D1191, it, the exact Player/API operation and the first timestamp at which it appears. - Save device ID, last notification, connection generation and failing object pointer; do this before ejecting media, reconnecting a device, canceling a job or rebuilding the Player object.
- correlate the result with PnP instance and interface path, WMDM service-provider CLSID, device/partnership ID, connection generation, storage object and capacity, format-support result, firmware version, operation callback and first device or transport HRESULT.
- Reproduce once with the original source and destination, then apply only this change: discard stale interfaces and re-enumerate if the device is still connected.
- Create a fresh operation generation and verify that the original call advances beyond the no longer available boundary.

Change the smallest responsible condition
The targeted action is to discard stale interfaces and re-enumerate if the device is still connected. While retesting it, keep unrelated media, device, playlist and network values unchanged.
When verifying it, do not assume the old interface pointer remains valid after reconnect; Re-enumerate the device and storage objects and correlate the failure with the same connection generation.
