On a Windows Vista Service Pack 1 or Windows Server 2008-based computer, when you use the built-in backup application to back up data to multiple discs in a slim slot optical device drive, the first disc may become unreadable after you eject it
Consider the following scenario:
- You have a computer that is running Windows Vista Service Pack 1 or Windows Server 2008.
- You use the built-in backup application to back up data to a slim-slot optical disc drive.
- The backup data requires multiple discs to save.
- After the first disc is full, you press the eject button to eject the disc.
In this scenario, you receive a “Preparing to eject” message in the notification area. However, the disc does not eject. When you press the eject button again, the disc ejects. However, when you put the disc back into the drive, the disc may be unreadable.
