It started with watching movies on the HD and they buffered which makes no sense for local files. I decided to move everything off the drive just in case and it copies at 100Mb/s for hundreds of gigs then drops to 5Kb/s and hangs... It eventually does copy if I leave it over days, but clearly there are "dark spots" on the drive based on how certain files or folders copy like crap while others are fine. I've run HD tune, Seatools, and Checkdisk. There are no bad sectors, but even the scans go to crap in parts when it hits the "dark spots".
I have the drive empty and removed the partition in Windows. I recreated and long formatted the drive, but it still seems to be a problem. Is the drive just screwed or is there a way around this. I'm doing a Seatools Long Generic test right now, but of course it will take most of the day or until tomorrow to finish.
The weird thing is that I have two hard drives that both exhibit this problem at the same time which was almost immediately after I changed to a generic PSU. I ahave a really nice Corsair PSU now (just bought it to make sure it wasn't the issue), but the timing was weird.
Any help or ideas are appreciated. I've considered using Sardu or an Ubuntu boot disk to hit the drives harder with other tools and less Windows involvement, but am I wasting my time? Are the drives just completely toast? Bad sectors I understand, but this weird "no mans land" issue with the drives is completely new to me.
It's an internal hard drive about 3Gb in size. Western Digital. I've already tried switching cables and SATA ports.
