What does HRESULT 0xC00D1137 (NS_E_WMPBR_DRIVE_INVALID) mean?

NS_E_WMPBR_DRIVE_INVALID

Diagnosing NS_E_WMPBR_DRIVE_INVALID during Windows Media rights backup or connectivity

NS_E_WMPBR_DRIVE_INVALID (0xC00D1137) is returned when the selected backup/restore location is not an acceptable accessible volume for this operation.

Preserve one asynchronous operation record containing the selected path, event listener, network resource and license-store status. Record what the Player had already completed because later retries often replace the original evidence. The specific rejected condition is the selected backup/restore location is not an acceptable accessible volume for this operation.

Safe controlled retry

1. Start from the original call and log 0xC00D1137 together with its object and operation phase.
2. Collect drive type, mount state, free space, path syntax, access token and whether the source files are present before changing the machine.
3. Use this single-variable test: copy the complete backup set to a local writable directory and retry from that unchanged set.
4. Repeat on a fresh object if the original predates a configuration, device or resource change.
5. Validate the expected next operation, not just initial open or object creation.
