Found five (5) unused hard drives under my bed.
Four out of them (4/5) are probably for booting from.
At least one of them (1/4) is faulty.

Checked them just now.
- 2/5 are beyond hope
- 1/5 is making weird noises and also an issue related to me
    being a noob. It was a faulty hard disk that I used for
    my first attempt to install Linux on something.
- 1/5 needs a power cable so I couldn't check it
- 1/5 is from *1999* and I don't have an IDE to connect to it
