SUMMARY
=======
 
Because of physical read limitations of some CD-ROM drives, you may not be
able to access some files and directories on the Ultimate Robot 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 three directories,
listed below, from the Ultimate Robot CD-ROM:
 
DIRECTORIES          LOCATION ON DISC
-----------          ----------------
 
MMCAT\DIBS2             569-570 MB
MMCAT\DIBS1             567-569 MB
GOODIES\ROBOTOID        532-547 MB
 
To test for specific drive-capacity limitations, try to access the
files listed below:
 
FILES                          LOCATION ON DISC
-----                          ----------------
 
GOODIES\ROBOTOID\ROBOTOD4.AVI        543 MB
GOODIES\KINEMATX\ANIM630B.AVI        520 MB
AURWTIME\WAVESOUND\SNDFIL.WAV        499 MB
 
The Ultimate Robot CD-ROM contains 570 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 you have 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.
 
Try to copy one of the following files 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 DISC
-----                          ----------------
 
GOODIES\ROBOTOID\ROBOTOD4.AVI        543 MB
GOODIES\KINEMATX\ANIM630B.AVI        520 MB
AURWTIME\WAVESOUND\SNDFIL.WAV        499 MB
 
If the following error message appears
 
  CDR101: Not Ready
 
the CD player cannot read the disk at the specified location.
 
If the file copies, test the file's integrity by 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
 
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-
ROM at that location.
