When I go under C: and click properties, it tells me I only have 74GB of Hard
Drive Space; but I have a 80 GB Hard Drive. Why is that?

Happens in just about every version of Windows. Hard drive manufacturers
calculate space to the power of 10. Windows calculates to the power of 2.
1 GB to a hard drive manufacturer manufacturer is one million bytes.
In Windows it is 1,073,741,824.

74x the number that Windows uses = 79,456,894,976 or what the hard drive
manufacturers like to round off to 80GB.
 
Thank you so much. I had no idea about that. I was wondering why I was being
shorted 6 Gs. Very good answer. :) You rock.
