Samsung patents storage drive that checks if it is causing power errors

This patent describes a method where a storage device monitors the power voltage it receives from a computer or other host. If it detects a power error, the drive compares its own internal readings with real-time data from the host to determine if the drive itself is causing the issue.

Why it mattersThis helps technicians and users quickly identify whether a power problem is coming from the storage drive or the main computer, simplifying troubleshooting.

In the filing’s own words

A method for operating a storage device according to some example embodiments may include monitoring a power supply voltage provided by an external host device; detecting an error of the power supply voltage; generating self-monitoring data of the power supply voltage, and requesting real-time state information to the external host device, based on detection of the error of the power supply voltage; receiving the real-time state information from the external host device; generating result data for indicating whether the error of the power supply voltage is caused by the storage device based on the self-monitoring data and the real-time state information; and transmitting the result data to the external host device.

What exactly they claim (claim 1)

1. A method for operating a storage device comprising: monitoring a power supply voltage provided by an external host device; detecting an error of the power supply voltage during an operating period of the storage device; generating self-monitoring data of the power supply voltage during the operating period of the storage device, and requesting real-time state information from the external host device, based on detection of the error of the power supply voltage during the operating period of the storage device; receiving the real-time state information from the external host device; generating result data for-indicating whether the error of the power supply voltage is caused by the storage device based on the self-monitoring data and the real-time state information; and transmitting the result data to the external host device.
