The hard disk shows up in devices under device management but not in explorer and it doesnt work. I went to disk management and tried to initialize the drive, but it says cyclic redundancy error. It shows up in disk management as unallocated and not initialized. I double checked the sata cables and switched them too. I tightened them as well but it doesnt seem to work. What do I do. Please help me as this is a new build and im really tensed. Thanks a lot. [The model of the drive is - WDC WD10EZEX 08WN4A0]
