I have two external usb3 hard drives (WD Passports) and I wanted to back up 900GB from one onto the other (empty) one. The laptop is a Dell 6440, and am using the usb3 ports on it, and it has 8GB Ram, BUT, I highlighted all the files and folders in the source disk, r/clicked, then clicked on send to, and chose the destination drive, and it's saying about 23 hours remaining and it's doing 3.64 MB/second?? Has anyone any ideas where it's going wrong please? What do the people here use to do fast backups like this please?
