I have found: IMPORTANT: The following precautions should be taken before installing the firmware update.Before updating the firmware on your drive, make sure you have a copy of all the data on your drive stored on a separate device.
Firmware is held in non-volatile memory devices such as ROM, EPROM, or flash memory.
Changing the firmware of a device may rarely or never be done during its lifetime; some firmware memory devices are permanently installed and cannot be changed after manufacture.
A television remote control is an example of an engineered product that contains firmware.
The firmware monitors the buttons, controls the LEDs, and processes the button presses in order to send the data in a format the receiving device, in this case, a television set, can understand and process.
After the update completes, you can restart the hosts.
