Apparatus, methods, and computer-code for handling an impending decoupling between a peripheral device and a host device

A method of handling impending peripheral device decoupling, comprising:

• determining at a peripheral device whether there is a data flow between the peripheral device and a host device;
• monitoring wired electrical connectivity via an onboard detector of the peripheral device in response to determining that there is the data flow between the peripheral device and the host device;
• detecting at the onboard detector of the peripheral device, while electrically coupled to a host-side interface of the host device via a device port of the peripheral device, an impending loss of wired electrical connectivity with the host device, the device port operative for data exchange between a non-volatile memory of the peripheral device and the host device;
• determining whether the detected impending loss of wired electrical connectivity presents a risk to data in the data flow;
• providing a signal from the peripheral device to trigger a damage reduction process at the host device in response to a combination of detecting the impending loss of electrical connectivity and determining that there is the risk to the data in the data flow between the host device and the peripheral device;
• providing a user alert at the peripheral device indicating the impending loss of wired electrical connectivity in response to the combination of detecting the impending loss of wired electrical connectivity and determining that there is the data flow between the host device and the peripheral device;
• and
• ceasing, by the onboard detector of the peripheral device, a monitoring of the impending loss of wired electrical connectivity when there is no data flow between the host device and the peripheral device.

A host device, comprising:

• a host-side interface operative to electrically couple the host device to a peripheral device;
• a controller in communication with the host-side interface, the controller operative to receive from an onboard detector of the peripheral device an indication of a detected impending loss of wired electrical connectivity with the peripheral device while the host device is electrically coupled to the peripheral device, the controller operative to respond to the indication of the impending loss of wired electrical connectivity by determining whether there is a data flow between the host device and the peripheral device;
• an alert mechanism operative to provide a user alert in response to a combination of the indication of the impending loss of electrical connectivity and the determination that there is the data flow between the host device and the peripheral device, wherein no user alert is provided when there is no data flow between the host device and the peripheral device;
• the controller operative to determine whether the impending loss of wired electrical connectivity presents a risk to data in the data flow, the controller operative to trigger a damage reduction process in response to determining that the impending loss of electrical connectivity presents a risk to the data;
• and
• the controller operative to provide, while the peripheral device remains coupled to the host device to permit data exchange, an indication to the peripheral device to cease monitoring of the impending loss of wired electrical connectivity when there is no data flow between the host device and the peripheral device.

A method of operating a peripheral device, comprising:

• while a device port of the peripheral device is coupled to a host-side interface of a host device, activating an onboard detector of the peripheral device in response to data flow between the peripheral device and the host device;
• monitoring wired electrical connectivity via the onboard detector of the peripheral device in response to the data flow between the peripheral device and the host device;
• detecting by the onboard detector an impending loss of the wired electrical connectivity with the host device, the device port operative for data exchange between a non-volatile memory of the peripheral device and the host device;
• determining whether the impending loss of wired electrical connectivity presents a risk to data in the data flow;
• providing a signal from the peripheral device to trigger a damage reduction process at the host device in response to determining that the impending loss of wired electrical connectivity presents a risk to data in the data flow;
• providing a user alert of the impending loss of wired electrical connectivity in response to a combination of detecting the impending loss of wired electrical connectivity with the host device and determining that there is the data flow between the host device and the peripheral device;
• and
• ceasing, while the peripheral device remains coupled to the host device to permit data exchange, the monitoring via the onboard detector when the data flow between the peripheral device and the host device completes.

A non-volatile storage device, comprising:

• a non-volatile memory for data storage;
• a device port for coupling with a host device and for data exchange between the non-volatile memory and the host device;
• an onboard detector that is operative, when the non-volatile storage device is coupled with the host device to permit data flow via a wired connection including the device port, to detect an impending loss of wired electrical connectivity between the non-volatile storage device and the host device and in response to a detection of the impending loss of wired electrical connectivity, to determine whether there is a data flow between the host device and the non-volatile storage device and whether the impending loss of wired electrical connectivity presents a risk to data in the data flow;
• and
• an onboard user alert mechanism that is operative to provide at the non-volatile storage device, a user alert of the impending loss of wired electrical connectivity in response to a combination of the detection of the impending loss of wired electrical connectivity and a determination that there is a data flow between the host device and the non-volatile storage device;
• wherein the non-volatile storage device is operative to provide a signal to trigger a damage reduction process at the host device in response to a combination of detecting the impending loss of wired electrical connectivity and determining that there is the risk to the data in the data flow between the host device and the peripheral device.
