SUMMARY
=======
 
Because of physical read limitations of some CD-ROM drives, you may not be
able to access some files and directories on the Bookshelf 1994 CD-ROM.
This article lists some of those files and directories and explains how to
test your CD-ROM drive.
 
MORE INFORMATION
================
 
The CD-ROM drive may have difficulty reading the final two folders, listed
below, from the CD-ROM.
 
FOLDERS              LOCATION ON DISK
-------              ----------------
 
Mmcat\Dibs2          475-477 MB
Mmcat\Dibs1          474-475 MB
 
To test for specific drive-capacity limitations, try to access the
following files:
 
FILES                       LOCATION ON DISK
-----                       ----------------
 
Mmcat\Dibs2\Ngpopd.dib      477 MB
Mmcat\Dibs1\Strpopd.dib     475 MB
 
The Bookshelf 1994 CD-ROM contains 477 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
programs.
 
Attempt to copy one of the following files to the hard disk drive.
 
FILES                       LOCATION ON DISK
-----                       ----------------
 
Mmcat\Dibs2\Ngpopd.dib      477 MB
Mmcat\Dibs1\Strpopd.dib     475 MB
 
For more information about how to accomplish this task in Windows, see your
Windows printed documentation or online help.
 
If the follow error message appears:
 
   CDR101: Not Ready
 
the CD-ROM player cannot read the disk at the specified location.
 
If the file copies, test its integrity by using FC.EXE with the /B (binary)
switch. For example, to compare the Ngpopd.dib file on your CD with the
Ngpopd.dib file on your hard drive, type the following at the MS-DOS
command prompt and press ENTER:
 
   fc  /b d:\mmcat\dibs2\ngpopd.dib  c:\ngpopd.dib
 
where your CD-ROM drive is drive D and your hard disk drive is drive C.
 
If you receive errors, the CD-ROM drive is having problems reading the
CD at that location.
