So I just built my new PC a few days ago and I created a partition on my M.2 for windows, then I tried to create a partition on my 4TB WD Black hard drive. At first, the Windows disk management tool gave me an I/O device error, so I unplugged the sata power from the power supply and plugged it back in and it started to work properly. Fast forward to today, I booted up my PC and the hard drive partition disappeared from file explorer and again I'm having the I/O error. I unplugged the power like I did before and the drive isn't even showing up at all anymore. Any help would be greatly appreciated.
