I recently built a computer, and I cannot connect the hard drive.

I built a computer with an SSD, and a hard drive, so I decided to boot my OS onto my SSD so that it would boot faster. I did that, and now that I have my computer working, I need to find a way to connect my hard drive. It is manually connected with both cables from the power supply and the motherboard, and shows up in the BIOS. Whenever I go to windows, the computer says that I only have 3 drives, and optic, boot drive (my SSD), and another hard drive that only has 300 megabits. I go back to the BIOS to see how much space my hard drive (I know that it should me 1 terabytes) has. It has 1 terabyte.
Thanks in advance

The "another hard drive that only has 300 megabits" most likely is Mega Bytes, 300MB, not bits. 8 bits = 1 Byte. The long-standing significance is b = bits and B = Bytes.
Did you look in Computer Management, Disk management section to see if the 1TB drive is seen and has any partitions? If the 1TB is not new the 300MB would be quite normal but you should also have a larger partition. If you don't you can create and format it there then assign a drive letter before it can be seen in File Explorer [renamed from Windows Explorer].

I do know the hierarchy of SI prefixes , but I misspoke about the drive size. It says 300 Megabytes. I did look in computer management, but I am only able to view the properties about the drive. It says that I have my Samsung drive, and my Western Digital drive, but I am unable to see how much space the drive has on it.

I was actually able to find the problem. The 300MB File was a small allotment of my 1tb hard drive, so I made a new one assigned with a letter. Thanks for the help

You're welcome.
