CD or DVD rotational speed
 

I tried and failed searching for this answer, not only on this forum, though it could well be answered already. However, the "similar thread title search" works a lot better than the forum search. How about placing it where it can be more easily reached?

Anyway, is there a command to tell a CD or DVD drive to spin slower? The main reason is to reduce vibrations and noise. Many times out of several, the higher speed is unnecessary and annoying. Most notably while watching movies.

As it is, I am running Debian stable (etch), but my question is generic.

For some CD/DVD-ROM drives the following commands may be useful
where <speed> is an integer number (2, 4, 8, ...) representing speed of 2x, 4x, 8x and so on, respectively. Other than the above commands, I know only an application for KDE called "Set CD-ROM Speed" which requires kmdr-executor to run (Kommander runtime files).
