DOCUMENT:Q151311 22-OCT-1999 [mastering] TITLE :Mastering VB: Testing CD-ROM Drive for File Access PRODUCT :Microsoft Mastering Series PROD/VER::1.0 OPER/SYS: KEYWORDS:kbmm kbsetup ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - MSPRESS Mastering Microsoft Visual Basic 4.0 ISBN 1-55615-913-7, version 1.0 ------------------------------------------------------------------------------- SUMMARY ======= Because of physical read limitations of some CD-ROM drives, your CD-ROM drive may deny access to some of the files and folders on the Microsoft Mastering Visual Basic compact disc. This article lists some of those files and supplies a method to test your CD-ROM drive. MORE INFORMATION ================ The CD-ROM drive may have difficulty reading the final two folders, listed below, from the Mastering Visual Basic compact disc: Folders Location On Disk ------- ---------------- Root directory 447-447 MB Master 420-439 MB To test for specific drive-capacity limitations, try to access the following files: Files Location On Disk ----- ---------------- Setup.lst 447 MB Master\Mvb.m14 437 MB The Mastering Visual Basic compact disc contains 451 MB of data. The final file on the disc is Setup.lst. Testing Your CD-ROM Drive ------------------------- To ensure the integrity of files that have been copied from your compact disc to your hard 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 the following files to the hard drive. Files Location On Disk ----- ---------------- Setup.lst 447 MB Master\Mvb.m14 437 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 drive cannot read the disc 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 setup.lst file on your CD-ROM with the setup.lst file on your hard disk drive, type the following at the MS-DOS command prompt and press ENTER: " fc /b d:\setup.lst c:\setup.lst " (without the quotation marks) If you receive errors, the CD-ROM drive is having problems reading the disc at that location.
