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.
