10-24 Chapter 10 Managing Data Storage
To troubleshoot an audio playback problem, take the following additional steps:
■ Verify that the sound card is properly configured and functional.
■ Verify that the speakers are plugged in and turned on.
■ Verify that the sound has not been muted.
■ Verify that the audio cables connecting the CD/DVD to the sound card are properly
connected.
■ Make sure that the CD is clean.
If the CD device supports it, you can enable the digital CD playback feature in the
drive’s Properties dialog box in Device Manager. On the Properties tab, select the
Enable Digital CD Audio For This CD-ROM Device check box. Digital CD playback
requires that CD devices support digital audio extraction (DAE), which older devices
might not support. When digital CD playback is enabled, the CD-ROM drive does not
have to be connected to the sound card, and audio output from the headphone jack on
the CD-ROM drive is disabled.
Removable Storage Media
Removable storage media consist of devices such as disks, tape, and optical media,
which are stored either online in the form of information libraries or offline on a shelf
or in a file drawer. These media are used primarily for backup of applications and data.
They are also used to archive data that is not accessed frequently.
Previous versions of Windows (pre–Windows 2000) did not provide strong support for
removable devices. Each application that required access to a removable device
needed a custom solution for accessing and managing removable storage media. Windows
XP centralizes the management of these devices with Removable Storage technology.
Removable Storage allows the operating system to manage removable media
centrally, and applications gain access to removable devices through the Removable
Storage interface. Devices with drivers that have been written to take advantage of
Removable Storage are easily accessible and sharable by both the operating system and
applications.
Removable Storage uses the concept of media pools to organize removable media.
Media pools group media by usage, allow media to be shared by multiple applications,
control media access, and provide for tracking of media usage. Other concepts of
removable storage include the following:
Media units The actual devices that store information, such as a CD-ROM, tape cartridge,
or removable disk.
