Why is my computer sluggish after plugging in the Seagate Backup Plus portable drive?
Seagate Backup Plus, once I ran a backup it seemed to have slowed down my computer and the mouse is really sluggish. When I unplugged the portable drive everything started working fine. I am using it on a Windows 7 Dell computer with USB 3.0. I set it up to do a backup daily starting at 7 pm. Any suggestions on what may be happening or what I may have done?
