Error accessing data from CD-ROM

[Warrier]

My application in VB 6.0 gives me the error.The application reads data in access table on a CD-ROM.Error occurs only on Windows 98.

Error message is as follows
"Error reading CD-ROM in drive D:
Please insert CD-ROM
With serial number # in drive D:
If the CD-ROM is still in the drive it may require cleaning
Press Enter for Ok or Esc to cancel :Ok"
Anybody has any info on this.???
