Pioneer dvr k12d makes a sound

I have a satellite a45 s250.
It came with a pioneer dvr k12d.

I started hearing a sound (like some starting sound) when I just open the dvd tray and close it. Same sound is heard when I boot.
It might be something to do when the dvd drive starts.
Other than this problem, the dvd rw seems to work flawlessly.

When I bought the notebook, at the time of boot up or when I open and close the dvd tray, I didn’t hear any sound. One of my friends has the same laptop, and this starting sound is not heard in his’.

Could you guys let me know how to stop this sound?

Thanks

You cannot unless you re-assemble and re-calibrate the whole drive…
