I've had my pc for about a month now and at first, I was able to have my hard drive detected, but then I didn't pay attention and now it isn't. When I go to BIOS I enabled the correct SATA ports and it detects the hard drive. But now when I go into Disk Manager or This PC the hard drive is not detected. My hard drive is the Seagate Baracuda 2TB HDD 7200 RPM. Please help me, I have spent hours on this.
