Set-cd-rom-speed is an application for setting CD-ROM and DVD-ROM drive speed, written with KDE Kommander. Fast CD-ROM and DVD-ROM drives have one big disadvantage over older and slower models in that they are often quite loud because of the disk spinning very fast in the drive. Using set-cd-rom-speed, you can decrease the drive's speed and thus reduce the annoying noise.
