My external hdd is here
http://www.amazon.com/gp/product/B002QEBMB4/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
It's always worked very well, with copy speeds of around 90-100 mbps on usb 3.0. Last week though, out of the blue, it started copying so slow. I try to copy seasons of tv shows, and it starts out at 99mbps, for about 10 seconds, then it drops quickly to around 700-900kbps.
What could be the problem here? It cant be the port, as my other drives (seagate) work perfectly fine with my pc.
Please help me.
