Very Noisy DVD-ROM

For no apparent reason the dvd-rom in my HP computer makes one heckva noise whenever I insert a disk. Sometimes it will read the disk but more often than not it’ll just make an awful seek noise. Any clues out there??

Is the disk in good condition? Sometimes my drive just doest read cd’s or dvd’s if they are damaged or I improperly burned them. What is it that the dvd is trying to read, as in what program?
