Consider the following scenario:

• On a Windows Server 2008-based or Windows Vista Service Pack 1 (SP1)-based computer, an application writes to a file on a local file share.
• This file is scanned by using memory-mapped files. This scanning process typically occurs when certain antivirus software is installed on the computer.

In this scenario, additional character spaces may be added to sections of the file. Therefore, the file becomes corrupted.

Symptom 1

Consider the following scenario:

• On a computer that is running the release version of Windows Vista, a volume on the hard disk is corrupted.
• You restart the computer.

In this scenario, a black screen is displayed, and you cannot log on to the computer except in safe mode.

Symptom 2

Consider the following scenario:

• On a computer that is running Windows Vista Service Pack 1 (SP1) or Windows Server 2008, a volume on the hard disk is corrupted.
• You restart the computer.

In this scenario, the Autochk.exe application stops responding, and this prevents the restart process from continuing. If you press a key to cancel the Autochk.exe process, you can log on to the computer as expected.

Note: By default, the Autochk.exe application automatically tries to fix any hard disk corruption during startup. After Autochk.exe fixes the disk corruption, the system automatically restarts.

When you attempt to install Adobe Creative Suite 3, you see the error message, “The Installer Database is corrupt. Please Contact Adobe Customer Service if this problem continues.”

Consider the following scenario. You have configured offline file folders on a computer that is running Windows Vista. At the same time that offline files are synchronized, the Windows Vista-based computer switches to suspend mode. Later, you try to synchronize offline files.

In this scenario, the operation to synchronize offline files appears to succeed. For example, the file metadata, such as file size, timestamp, and other metadata is identical. However, the files on the server are corrupted, and the file contents are randomly different.

After you install Windows Vista so that the computer can start either in Windows Vista or in Microsoft Windows XP, you cannot start Windows XP. When you try to start the computer by using Windows XP, you receive an error message that resembles the following:

Windows could not start because the following file is missing or corrupt:

C:\Windows\system32\ntoskrnl.exe. Please re-install a copy of the above file.

After you install Windows Vista in a dual-boot configuration together with Microsoft Windows XP, you receive an error message that resembles the following when you try to start the computer by using Windows XP:

Windows could not start because the following file is missing or corrupt:

C:\Windows\system32\ntoskrnl.exe. Please re-install a copy of the above file.
