Firmware update

Hi, is it safe to update the firmware without losing stuff? what the new firmware does and adds?
to add it’s WD Green 120gb and the new firmware is UE4500000

FW update is not data destructive however it is always a good idea to have a backup before updating the FW>

IS IT Safe to upgrade the latest Firmware ue450000,anyone?
