If I am opening a large MS Excel document from the hard drive ( or busy working on the pc) and I insert a cd or dvd into the cd/dvd drive, why does my machine nearly stop everything untill the cd has been read? Once the cd/dvd contents is displayed in My Computer everything goes back to normal speed again. (It seems like the machine uses all of its resources to read a cd/dvd.) Question 2: is there a way to solve this?

I get this "problem" on my desktop pc also.
