= SUMMARY =

Because of physical read limitations of some CD-ROM drives, some files and directories on Art Gallery CD-ROM may be inaccessible. This article lists those files and tells 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 Art Gallery CD-ROM::

DIRECTORIES LOCATION ON DISK ———– —————-

641MB 640-641MB  638-640MB

To test for specific drive-capacity limitations, try to access the files listed below:

FILES LOCATION ON DISK —– —————-

M2GPTIME\1314SKUL.SK 621MB ARTGALL.DAT 601MB M2GPDATA.3 595MB

The Art Gallery CD-ROM contains 641 MB of data. The final file on the CD-ROM is ARTGALL.ACM.

Testing Your CD-ROM Drive
To ensure the integrity of your 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 may occur while running a CD- ROM application with Windows.

Attempt 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 DISK —– —————-

M2GPTIME\1314SKUL.SK 621MB ARTGALL.DAT 601MB M2GPDATA.3 595MB

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 msadpcm.acm file on your compact disc with the msadpcm.acm file on your hard disk drive, type the following at the MS-DOS command prompt and press ENTER:

fc /b d:.acm c:.acm

If you receive errors, the CD-ROM drive is having problems reading the CD-ROM at that location.
