NS_E_BAD_DISK_UID
Diagnosing NS_E_BAD_DISK_UID
NS_E_BAD_DISK_UID identifies a specific boundary in the legacy Windows Media Services/NetShow server path: disk parameter has incorrect uid parameter.parameter. For NS_E_BAD_DISK_UID, treat the code as the result of the component that owns that boundary, not as proof that every part of streaming, storage, or networking has failed in the bad disk uid c00d0064 case.
Where the result is raised
The early NetShow Theater architecture distributed titles across Content Servers and managed content disks with stored identity and layout metadata in the bad disk uid c00d0064 case. Disk online/offline, rebuild, restripe, paging and inter-server links are distinct states; a healthy Windows volume alone does not prove that the media subsystem accepts the member in the bad disk uid c00d0064 case.
Evidence to capture before retrying
Record content-server identity, disk UID, control-block version, filesystem version, rebuild or restripe state, affected title/block, free space, I/O status, and the first component that marked the member unavailable in the bad disk uid c00d0064 case. For NS_E_BAD_DISK_UID, keep the first lower-level Win32, socket, storage, parser or plug-in result that appears before NS_E_BAD_DISK_UID; this HRESULT is often the server-facing summary in the bad disk uid c00d0064 case.
A controlled diagnostic sequence
To verify NS_E_BAD_DISK_UID, first reproduce the original call with the same server object and content in the bad disk uid c00d0064 case. Next for NS_E_BAD_DISK_UID, capture the exact supplied value, validate it against the owning API or protocol field, and change only that value in the bad disk uid c00d0064 case. Finally for NS_E_BAD_DISK_UID, create a fresh request or session and confirm that processing advances beyond the NS_E_BAD_DISK_UID boundary instead of merely returning a different error from an earlier stage in the bad disk uid c00d0064 case.
Interpret the observations
| Observation | Meaning |
|---|---|
The same operation returns NS_E_BAD_DISK_UID with identical object identity | The failure is repeatable at disk parameter has incorrect uid parameter.parameter; investigate that owner before broad system changes in the bad disk uid c00d0064 case. |
| A lower-level error is logged first | For NS_E_BAD_DISK_UID, use that earlier result as the root diagnostic signal in the bad disk uid c00d0064 case. NS_E_BAD_DISK_UID may only map it into the Windows Media namespace in the bad disk uid c00d0064 case. |
| A fresh session passes this check but fails later | A later-stage result means the original NS_E_BAD_DISK_UID condition was cleared in the bad disk uid c00d0064 case. Diagnose the later code as a separate pipeline stage in the bad disk uid c00d0064 case. |
| Only another client or title fails | For NS_E_BAD_DISK_UID, compare object-specific configuration, content metadata and limits; this argues against a server-wide repair in the bad disk uid c00d0064 case. |
Verification checklist
- Capture
0xC00D0064,NS_E_BAD_DISK_UID, the exact API or administrative action, and the first occurrence time in the bad disk uid c00d0064 case. - Save content-server identity, disk UID, control-block version, filesystem version, rebuild or restripe state, affected title/block, free space, I/O status, and the first component that marked the member unavailable in the bad disk uid c00d0064 case.
- For
NS_E_BAD_DISK_UID, check the current state before changing it; stateful server handles and sessions can become stale after reconnect, restart, rebuild, or media replacement in the bad disk uid c00d0064 case. - For
NS_E_BAD_DISK_UID, apply one controlled correction: capture the exact supplied value, validate it against the owning API or protocol field, and change only that value in the bad disk uid c00d0064 case. - Retest
NS_E_BAD_DISK_UIDwith a new operation generation and verify both the return code and the expected stream, file, disk, title, or session behavior in the bad disk uid c00d0064 case.
Code-specific evidence map
| Facet | Question for this result |
|---|---|
| Object | For the bad-disk marker of NS_E_BAD_DISK_UID, record which server-side object was selected and whether its identity still matches the caller's handle in the bad disk uid c00d0064 case. This separates disk parameter has incorrect uid parameter.parameter from a generic disk failure in the bad disk uid c00d0064 case. |
| State | For the disk-uid marker of NS_E_BAD_DISK_UID, record the lifecycle state immediately before the failing request and the transition that was expected next in the bad disk uid c00d0064 case. This separates disk parameter has incorrect uid parameter.parameter from a generic disk failure in the bad disk uid c00d0064 case. |
| Input | For the uid-bad marker of NS_E_BAD_DISK_UID, record the exact path, address, index, title, stream, device, or configuration value supplied to the owner in the bad disk uid c00d0064 case. This separates disk parameter has incorrect uid parameter.parameter from a generic disk failure in the bad disk uid c00d0064 case. |
| Capacity | For the bad-disk marker of NS_E_BAD_DISK_UID, record the active sessions, open files, bitrate, bandwidth, disk space, or other limit relevant to this operation in the bad disk uid c00d0064 case. This separates disk parameter has incorrect uid parameter.parameter from a generic disk failure in the bad disk uid c00d0064 case. |
| Lower Layer | For the disk-uid marker of NS_E_BAD_DISK_UID, record the first socket, filesystem, parser, device, registry, or component result recorded before the HRESULT in the bad disk uid c00d0064 case. This separates disk parameter has incorrect uid parameter.parameter from a generic disk failure in the bad disk uid c00d0064 case. |
| Generation | For the uid-bad marker of NS_E_BAD_DISK_UID, record whether a reconnect, service restart, disk rebuild, or object recreation made the original handle stale in the bad disk uid c00d0064 case. This separates disk parameter has incorrect uid parameter.parameter from a generic disk failure in the bad disk uid c00d0064 case. |
The lowercase diagnostic label bad disk uid is only a troubleshooting shorthand for this page; the programmatic identity remains NS_E_BAD_DISK_UID and HRESULT 0xC00D0064.

For automation, log the symbolic name as well as the numeric HRESULT in the bad disk uid c00d0064 case. The symbolic name preserves the Windows Media subsystem boundary that a generic COM error formatter can obscure in the bad disk uid c00d0064 case.
