Abstract
A data storage device is disclosed configured to connect to a host compute device via a power bus and at least one data bus, the data storage device comprising an I/O port configured to receive power from the power bus and provide data to and receive data from the host compute device via the at least one data bus, a timer configured to open a timing window when a cache flush command is received from the host compute device and close the timing window after a predetermined amount of time has expired or a host write command is received, and control circuitry configured to detect when the power from the host compute device is removed, determine whether the timing window is closed, and, if the timing window is closed, provide a warning alarm to indicate improper removal of the power from the host compute device.
