Storage device, an operating method of the storage device and an operating method of a computing system including the storage device and a host device

An operating method of a computing device that comprises a storage device and a host device for communicating with the storage device, the method comprising:

• detecting, by the storage device, a fault of the storage device;
• notifying, by the storage device, the host device of the fault;
• notifying, by the storage device, the host device of one or more recovery schemes for recovering the fault;
• and
• selecting, by the host device, one of the one or more recovery schemes;
• and
• recovering, by the storage device, the fault in response to the selected recovery scheme,
• wherein the selecting comprises:
• checking, by the host device, a status of the host device;
• and
• selecting, by the host device, the one or more recovery schemes in response to the status of the host device.

A storage device, comprising:

• a nonvolatile memory device;
• and
• a controller configured to control the nonvolatile memory device, wherein the controller comprises:
• a fault detection module configured to detect a fault of the nonvolatile memory device;
• a fault informing module configured to inform an external host device of the fault;
• a capability check module configured to inform the external host device of one or more recovery schemes for recovering the fault;
• and
• a recovery module configured to recover the fault in response to a recovery scheme selected by the external host device,
• wherein the fault detection module detects the fault of the nonvolatile memory device in response to an access request of the controller, wherein the access request of the controller is generated by the controller itself without a request of the external host device.
