Hi folks, I've got a 1TB Seagate external HDD that has a copy speed problem. It begins copying at the expected 60 mb/s rate before suddenly dropping to 0 after a minute or so, and then it fluctuates between 0 and 2mb. I can copy small files like individual songs without interruption but anything larger than 100mb gets the same problem. I ran chkdsk and it detected no errors or bad sectors, but when I do a long generic test or a Short Drive Self Test on SeaTools it fails. What could remedy the problem? I've reformatted the drive a couple times too and it hasn't helped.
