A few weeks ago i started getting Disk Read Error with my WD Cavier Blue 500gb Sata Drive so i went down to Bestbuy and picked up a Seagate Barracuda 500gb and now about 2 weeks later after i installed it into my PC i am getting Disk Read Errors again so now i am at a loss not sure what to do next. However it should be noted it very rarely happens which leads me to believe that maybe it is a bad sata cable ( seeing as i have it coiled and maybe i created a short in it). So any advice would be awesome.
Also i was told it could be my ram but i have already tested that with memtest. I also dont think it is mobo seeing as it is recognized in the BIOS.
