10-23Lesson 1 Managing and Troubleshooting Disks and Volumes
status, the disk might have failed entirely. Restart the computer to determine
whether the disk will become accessible. If it is a dynamic disk, attempt to repair
the disk by right-clicking it and selecting Rescan Disks.
Unrecognized The disk is an unknown type, and Windows XP cannot recognize it.
No Media This status is on drives with removable media, such as a CD-ROM drive,
when the drive is empty.
Volume status types and the recommended action (if required) are as follows:
Healthy The volume is accessible and has no detected problems.
Healthy (At Risk) If the disk status is Online (Errors), the volumes will be accessible,
but all volumes will display this status. Restoring the disk to Online will clear this
status from the volume.
Initializing The volume is in the process of initializing. No action is required. After
the initialization is complete, the volume should show a status of Healthy.
Removable Media
Windows XP contains built-in support for both CD-ROM and DVD-ROM devices. Win-
dows XP also supports a number of other removable media types, such as tape drives
and memory storage. This section covers the monitoring and troubleshooting of
removable media.
CD-ROM and DVD Devices
Most CD-ROM and DVD-ROM devices are Plug and Play–compliant and therefore
require little configuration. To view the status and configuration of these types of
devices, access the device’s Properties dialog box through Device Manager. The Gen-
eral tab of the device’s Properties dialog box indicates whether the device is function-
ing properly within Windows.
If Device Manager indicates that the device is installed and functioning, yet the
device does not appear to be working properly, there might be a physical problem
with the device installation, or the device itself might be faulty. If the disk tray does
not eject properly, or if the power/usage light-emitting diode (LED) indicators are
not illuminated, open the computer and verify that all connections have been prop-
erly established.
If a CD or DVD device appears to read data correctly but does not play back audio,
there is most likely a device driver problem, or additional required components are not
currently configured. Always verify that the device is listed in the Windows Catalog.
Also, make sure that the latest version of the device driver and associated software is
installed.
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 prop-
erly 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. Win-
dows XP centralizes the management of these devices with Removable Storage tech-
nology. 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 car-
tridge, or removable disk.
