I buy this NAS to use Time Machine, the first backup is going very well whenever I leave my house with my computer and I return home, the backup takes over and after a moment tells me the MyBookLive backup is in use. I reset the NAS 3 times and it's always the same. I was on the WD site and there is worse 3/4 of the links are dead, telephone contact is in English and it can not send mail. I will contact Amazon because then I bit more !!!!!!
