Diagnosing NS_E_BAD_DISK_UID

NS_E_BAD_DISK_UID identifies this Windows Media Services boundary: A disk has an incorrect UID; record the disk identity and the reported UID.

Why this boundary matters

This HRESULT identifies a Content Server storage transition or I/O boundary. Correlate disk UID, membership/layout generation, requested state and the first lower-level storage result before replacing media or rebuilding unrelated members.

Evidence to collect

FieldWhat to preserve
MemberDisk UID and Content Server identity for the member being changed or accessed.
LayoutCurrent layout/generation and membership visible to the same administrative object.
LifecycleOnline, rebuild, restripe or mirror state immediately before the failed transition.
Storage resultFirst lower-level I/O or management result tied to that same disk generation.

Decision rule

Do not replace or rebuild unrelated members until the failing disk UID and current layout generation identify the exact storage transition that failed.

Focused test

Capture the exact supplied value, validate it against the owning API or protocol field, and change only that value.

Verification

Repeat the requested operation against the same disk UID and current layout generation. Confirm the intended state transition or I/O completes and that the lower-level storage result does not reappear.

Technical references

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