So I have an external hard drive (Seagate 1TB) that I've had for a few years. I think it's starting to fail because whenever I copy some files to it, the speed drops down from 20-40mbps to 300kbps to just zero. It takes practically an hour to copy over 1gb. Drive still has over 60gb of free space. I'm still able to access all files and play them, so I'll be heading out soon to buy a new backup drive to move them to.

The drive passes chkdsk without fail, a short drive self test from SeaTools fails while a short generic one passes. I'm currently running a long generic one, but it's taking forever for a 1TB drive so I just want some answers. Is this thing really failing and would Seagate accept its return and replace it (it's still in its warranty period)
