I just received my Seagate Backup Plus 5TB hard drive. I formatted it to HFS+ (I'm using Mac), and started copying my previous 3TB hard drive to it. After copying around 2.5TB, it stopped responding. I tried the following things: -Unplug, restart Mac (waited for some time) -Disk Utility (doesn't show up) "However, shows up in System Report in USB section" -Terminal Command lines to show disks (doesn't show up) -DiskWarrior (doesn't show up) -Tried different USB 3.0 & Power Cables -Plugged it in a Windows machine, does not show up. -In Windows tried the Computer Management, Disk section. Shows up as offline disk, can't do anything to it Do you think there's anything that I can do to bring it back to life? Or should I return it? If I have to return it, I obviously will not go again with Seagate, but WD. Is there anything I can do to remove the data that was copied to it? Since it might be a casing problem, I don't want the manufacturer to get my data.
