RESOLUTION
==========
To resolve this issue, use the following methods in the order in which they are
presented.
Inspect and Clean the CD-ROM
----------------------------
To clean the Encarta World Atlas 2000 CD-ROM, use a CD-ROM cleaning kit, or
gently wipe the silver side of the CD-ROM with a soft, lint-free cotton cloth.
Do not use paper cloth which can scratch the plastic and leave streaks. When you
clean the CD-ROM, wipe from the center of the disc outward. Do not use a
circular motion.
If the issue continues to occur, clean the CD-ROM with a damp cloth or a
commercial CD cleaning solution. Dry the CD-ROM thoroughly before you insert it
into the CD-ROM drive.
If the issue continues to occur, proceed to the next method.
Make Sure You Are Using Protected Mode CD-ROM Drivers
-----------------------------------------------------
To make sure you are using protected mode (32-bit) drivers for your CD-ROM
drive:
1. Click Start, point to Settings, and then click Control Panel.
2. Double-click System.
3. Click the Performance tab, and then confirm that the File System entry is
32-bit. If the File System entry is "Some drives are using MS-DOS
compatibility", you may be using real mode (16-bit) CD-ROM drivers. If this
is the case, you may not be able to read certain files on the CD-ROM.
Contact the manufacturer of your CD-ROM drive to inquire about how to obtain
and install the latest version of the protected mode CD-ROM driver for your
CD-ROM drive.
4. Click OK, and then close Control Panel.
If the issue continues to occur, proceed to the next method.
Reduce CD-ROM Drive Caching
---------------------------
To reduce CD-ROM drive caching:
1. Click Start, point to Settings, and then click Control Panel.
2. Double-click System.
3. Click the Performance tab, and then click File System.
4. Click the CD-ROM tab.
5. Move the "Supplemental cache size" slider to the Small position.
6. In the "Optimize access pattern for" box, click "No read-ahead".
