It seems, likely it didn't happen overnight, but at least in the past week or two one of my three backup harddrives is now reporting as SATA 1. The worst part is it isn't only reporting as such, it's also speed is SATA 1 also.. this is a bit of an annoyance. For reference I currently run Samsung 840 Pro 128GB Samsung Spinpoint 1TB Samsung Spinpoint 1TB Seagate 400GB Now the problem drive is the Seagate, which also happens to be the newest drive in the computer being only about a year old, although it was picked up from another PC with light use. It was functioning fine as just a music storage drive, and even now the drive is fine for general use. I just noticed this when I defragged it and it decided to take the better part of all night which my spinpoints didn't take even remotely that long. Any insight? I even checked the BIOS and it is reporting the drive is saying it is SATA 1 so I can only assume hardware defect. Thanks for the help guys.
