SYMPTOMS
Consider the following scenario:
 * You format an optical disc by using the Live File System component on a Windows Vista-based computer.
 * You eject the disc soon after the formatting operation appears to be complete. Or, you eject the disc soon after you write a file to the disc, after the formatting operation is complete.
 * You reinsert the disc.

In this scenario, the disc appears to be blank. Any files that were written to the disc after the formatting operation are lost. Additionally, you cannot write any files to the disc. This problem occurs only when you use the Live File System component to format the disk, and then you eject the disk soon after a write operation has occurred.



CAUSE
This problem occurs for any one of the following reasons:
 * The brand of the disc may be incompatible with the burner. Try a different brand of media.
 * The disc may be defective. Try another disc.
 * The burner may have malfunctioned. For troubleshooting information, see the documentation that was included with the burner.
 * The burner or the disc may not support the speed that you used to burn the disk. Try using a slower speed.

Also consider the possibility that Windows Vista does not successfully run the close-session command when the disc is ejected. If the session is not closed correctly, the data that is written to the disc cannot be read. Therefore, the disc appears to be blank. Because this problem is timing-specific, this problem occurs only occasionally.

The following hotfix resolves only the specific problem in which Windows Vista does not successfully run the close-session command when the disc is ejected.
