The information in this article applies to:

 == Microsoft Automap Streets Plus for Windows, version 5.0 == 

= SUMMARY =

Because of physical read limitations of some CD-ROM drives, you may be denied access to some of the files and folders on the Microsoft Automap Streets Plus compact disc. 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 folder, listed below, from the Automap Streets Plus CD-ROM:

Folder Location On Disc —— —————-

Acmsetup-628 MB

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

Files Location On Disc —– —————-

Acmsetup50409.dll 627-628 MB Acmsetup.dll 619-620 MB Data_Hd.mad 615-616 MB Data_Cd.mad 137-615 MB

The Automap Streets Plus compact disc contains 628 MB of data. The final file on the CD-ROM is Acmsetup50409.dll.

Testing Your CD-ROM Drive
To test the integrity of files that you have copied from your CD-ROM drive to your hard drive, compare the files using the MS-DOS File Compare program (Fc.exe). You can use this 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 when you use CD-ROM drives with Windows programs.

Attempt to copy one of the following files to the hard disk drive:

Files Location On Disc —– —————-

Acmsetup50409.dll 627-628 MB Acmsetup.dll 619-620 MB Data_Hd.mad 615-616 MB Data_Cd.mad 137-615 MB

For more information about how to perform this task in Windows, see your Windows printed documentation or online Help.

If the following error message appears:

CDR101: Not Ready

the CD-ROM player cannot read the disc at the specified location. If the file does copy, test the file’s integrity by using Fc.exe with the /B (binary) switch. For example, to compare the Uss50409.dll file on your CD-ROM to the version of Uss50409.dll file you copied to your hard drive, type the following at the MS-DOS command prompt and press ENTER:

fc /b d:50409.dll c:50409.dll

where D is the letter of your CD-ROM drive, and C is the letter of your hard drive.

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