The issue is with an external HDD that had its power supply die. I've had this happen before, so I took it apart, took out the actual HDD from the case, plugged it into my own computer instead of another HDD that I have. No issue with the connectors, as the other HDD works just fine.
BIOS can see the new one(as slave), but it shows it as having the capacity of 0MB. Windows 7 Professional, which is the OS I have running, cannot see it at all.
The HDD in question is a WD Green 2TB: https://images-eu.ssl-images-amazon.com/images/I/81OsUOiXFcL._SL1500_.jpg
