Abstract:
Systems and methods for detecting legacy storage devices that may falsely and/or incorrectly report to host systems that they have removable media. Such false or incorrect reporting may cause the host system to periodically poll the storage device as to whether the device is ready for I/O processing. Such polling would be unnecessary and represent a waste of power expended by the host system. In one embodiment, the present system may implement processes that periodically poll storage media and update a database. The database would be a listing of storage devices indicating whether they truly have removable media or falsely report that they have removable media. In another embodiment, the present system may apply some heuristically testing to determine whether a storage device so falsely indicates removable media. In another embodiment, telemetry service may be used by a group of hosts to share data regarding such storage devices.
