The purpose of this utility is to detect the optical drive's (CD / DVD drives) Read/Write capabilities. When looking at the front of a computer which is not your own it is often difficult to tell whether the optical drive installed is either a CD ROM, CD Writer, CD Rewriter, DVD ROM, CD Rewriter + DVD Combo, DVD/CD Rewriter etc.
A utility like this is useful because CD and DVD drives don't often display their capabilities in the front and sometimes even if they do, they still can't been seen due to the design of the PC's case.
