Why is there noises when I play the games in my dreamcast?

Does anybody have any problem when they start your dreamcast with a backup. It starts to spin very fast and make alot of noises eve during the game?!?! Man, it gonna wear out my dreamcast soon! Anyone know how to fix that problem??

what game is it doing it with?

you need to have the image properly dummied or else the laser will seek longer than normal,
dummying moves data to the outside rim of the cdr and allows for faster loads
