I just built this new pc and I am having such a issue with it, I have a OS installed and cannot load many programs on it always getting errors, sometimes I get errors loading windows. I called Wester Digital and they sent me 2 new HD's I ran a test (Western Digital Data LifeGuard Diagnostic) as they advised me to do with the old HD's and gives me this error. The error was showing up on my 2 other HD's now on the new HD's I just got. I am running a MSI 770-C45 AM3 AMD 770 ATX AMD Motherboard AMD Phenom II X2 550 Black Edition Callisto 3.1GHz Socket AM3 80W Dual-Core Processor Model HDZ550WFGIBOX G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Dual Channel Kit Desktop Memory Model F3-12800CL9D-4GBNQ With 2 Western digital HD's 1 80GB 2 320GB Can it be that my motherboard is bad or more possible to be 2 more bad HD's??
