Inside my computer tower is one hard-drive. But I have two in my computer. It
is like the drive is seperated into a C: and D: drive. Why is this? Can I
rejoin them? If they were split, does it take away from the amount of space
there is there (say it's 400gB would this situation make it 350Gb one has
access to. The other 50Gb being a buffer of some kind?)?
