After installing VMWare, Windows Vista will recognize CDs and DVDs as blank Discs on your CD-ROM, CD-RW, DVD drives. When you try to access from “Computer”, it will pop the message
“Prepare this Blank Disk”
VMWare prompts to disable Auto-Run in Windows Vista to avoid performance and application issues during installation. If accepted, VMWare disables “Autorun” and thereon you face with this problem.
