-Modern CD-ROM drives can attain very high head speeds, yet some CD-ROM drives
-are capable of running at reduced speeds. There are several reasons that might

-  There have been reports of read errors at high speeds, especially
-  with badly pressed CD-ROMs. Reducing the speed can prevent data loss under

-  Many CD-ROM drives are annoyingly loud, a lower speed may reduce the noise.

-You can reduce the speed of IDE CD-ROM drives with <command>hdparm</command>,
-<command>setcd</command> or <command>cdctl</command>. It works like this:
-<screen>hdparm -E <replaceable>[speed]</replaceable> <replaceable>[cdrom device]</replaceable></screen>
-<screen>setcd -x <replaceable>[speed]</replaceable> <replaceable>[cdrom device]</replaceable></screen>
-<screen>cdctl -bS <replaceable>[speed]</replaceable></screen>

-If you are using SCSI emulation, you might have to apply the settings to the
-real IDE device, not the emulated SCSI device.
-</para>
-
-<para>
-If you have root privileges the following command may also help:
-<screen>echo file_readahead:2000000 &gt; /proc/ide/<replaceable>[cdrom device]</replaceable>/settings</screen>
-</para>
-
-<para>
-This sets prefetched file reading to 2MB, which helps with scratched CD-ROMs.
-If you set it to too high, the drive will continuously spin up and down, and
-will dramatically decrease the performance.
-It is recommended that you also tune your CD-ROM drive
-with <command>hdparm</command>:
-<screen>hdparm -d1 -a256 -u1 <replaceable>[cdrom device]</replaceable></screen>
-</para>
-
-<para>
-This enables DMA access, read-ahead, and IRQ unmasking (read the
-<command>hdparm</command> man page for a detailed explanation).

-<para>
-Please refer to
-"<filename>/proc/ide/<replaceable>[cdrom device]</replaceable>/settings</filename>"

-You may tweak the speed of SCSI CD-ROM drives with
-<command>sdparm</command>, you need version 1.03 or higher:
-<screen>sdparm --command=speed=<replaceable>[speed in kB/s]</replaceable> <replaceable>[cdrom device]</replaceable></screen>
-Speed must be specified in kilobytes per second, the drive will
-round it as appropriate. Please refer to the sdparm man page for
