Limiting Cdrom Speed

Is your CD-ROM drive louder than your vacuum cleaner? There are some situations where you might want to slow it down, such as when:

It's possible to limit the read speed of a mounted CDROM using a trick with the readcd utility. After the disk is set, but before mounting, run:

readcd dev=0,0 speed=8 sectors=0-0 f=/dev/null


readcd dev=ATAPI:/dev/cdrom speed=8 sectors=0-0 f=/dev/null

adjusting the dev and speed parameters accordingly. This should work with any drive that has "MMC" support. To find out the device numbers of your drives, use the cdrecord utility:

cdrecord -scanbus
