ERROR_BAD_DEVICE_PATH
The selected path to the device is invalid
ERROR_BAD_DEVICE_PATH indicates that the request used a device route that is no longer valid or cannot address the intended target. This may appear with removable hardware, multipath storage, stale handles, or topology changes.
Checks
- Reconfirm the device interface and instance identity.
- Discard handles opened before removal or path failover.
- Inspect controller, bus, and multipath state.
- Avoid persisting transient device paths as permanent identifiers.
Recovery
Enumerate the current device interfaces and reopen the target through a valid path. Ensure that the newly discovered device is actually the intended endpoint before issuing writes.
