If that is a real concern, then consider moving from a 56x CD-ROM reader to
something considerably slower, like a 4x or 8x. (Or try modifying the
driver to request a slower speed.) That will reduce the flood of I/O
messages and actions performed by the driver to recover from
badly-scratched media.
Another option is to invest in a good scratch-repair kit -- many scratches
can be filled with appropriate material that reduces the optical distortion
that causes the flood of activity in the first place.
Do you have a CD burner? Then extract the data and burn a new CD.
Finally, try investing in a CD-ROM player that has in-drive smarts to
recover from scratched media.
The choice is your.
