-------------------------------------------------------------------------------
 
SUMMARY
=======
 
Because of physical read limitations of some CD-ROM drives, the Microsoft
Encarta 1995 CD-ROM may deny access to some files and folders. This article
lists those files and supplies a method to test your CD-ROM drive.
 
MORE INFORMATION
================
 
The CD-ROM drive may have difficulty reading the final three folders, listed
below, from the Encarta 1995 CD-ROM:
 
+----------------------------------------+
| FOLDERS             | LOCATION ON DISK | 
+----------------------------------------+
| Mmcat\Dibs2         | 643-644 MB       | 
+----------------------------------------+
| Mmcat\Dibs1         | 641-642 MB       | 
+----------------------------------------+
| Encyc95\Mm\Interact | 619-640 MB       | 
+----------------------------------------+
 
To test for specific drive-capacity limitations, try to access the following
files:
 
+----------------------------------------------------+
| FILES                           | LOCATION ON DISK | 
+----------------------------------------------------+
| Mmcat\Dibs2\Ngpopd.dib          | 644 MB           | 
+----------------------------------------------------+
| Encyc95\Mm\Interact\Langbag.m12 | 625 MB           | 
+----------------------------------------------------+
| Encyc95\Mm\Avi\T041772a.avi     | 600 MB           | 
+----------------------------------------------------+
| Encyc95\Mm\Avi\T040372a.avi     | 581 MB           | 
+----------------------------------------------------+
| Encyc95\Mm\Avi\T040369a.avi     | 564 MB           | 
+----------------------------------------------------+
 
The Encarta 1995 CD-ROM contains 644 MB of data. The final file on the CD-ROM is
Mmcat\Dibs2\Ngpopd.dib.
 
Testing Your CD-ROM Drive
-------------------------
 
To ensure the integrity of files that have been copied from your CD-ROM drive to
your hard disk drive, compare the files using the MS-DOS File Compare program
(Fc.exe). This test can be used to determine if the CD-ROM subsystem is
functioning properly at the device driver or hardware level(s).
 
The Fc.exe utility is a useful method for testing problems related to general
protection (GP) faults or other critical errors (such as read errors or out of
memory messages) that can occur with Windows CD-ROM applications.
 
Attempt to copy one of the following files from the CD-ROM to your hard disk
drive. For more information about how to perform this task in Windows, see your
Windows printed documentation or online Help.
 
+----------------------------------------------------+
| FILES                           | LOCATION ON DISK | 
+----------------------------------------------------+
| Mmcat\Dibs2\Ngpopd.dib          | 644 MB           | 
+----------------------------------------------------+
| Encyc95\Mm\Interact\Langbag.m12 | 625 MB           | 
+----------------------------------------------------+
| Encyc95\Mm\Avi\T041772a.avi     | 600 MB           | 
+----------------------------------------------------+
| Encyc95\Mm\Avi\T040372a.avi     | 581 MB           | 
+----------------------------------------------------+
| Encyc95\Mm\Avi\T040369a.avi     | 564 MB           | 
+----------------------------------------------------+
 
If the following error message appears:
 
   CDR101: Not Ready
 
the CD-ROM player cannot read the disk at the specified location.
 
If the file copies, test the file's integrity using Fc.exe with the /B (binary)
switch. For example, to compare the ngpopd.dib file on your CD-ROM with the
ngpopd.dib file on your hard disk drive, type the following at the MS-DOS
command prompt and press ENTER:
 
   fc /b d:\mmcat\dibs2\ngpopd.dib c:\ngpopd.dib
 
If you receive errors, the CD-ROM drive is having problems reading the CD at that
location.
