After the installation of the latest driver and to access the tabs such configuration and on, by clicking at the home page the icon of WD, I noticed that WD was making a new backup and it did not take in care that previous data on it. Then I proceed to erase manually the previous data and now I checking that every thing is Ok. This version does not backup some executable drivers that are save in other hard USB disc. Also I noticed that the latest number version of this driver, does no appear in the Help tab.
