How to Disable Autochk During a Windows NT Reboot

• Microsoft Windows NT Workstation version 4.0
• Microsoft Windows NT Server version 4.0

SYMPTOMS

When a Windows NT-based computer is shut down improperly (for example, by a power failure), Autochk scans the hard disk the next time you start Windows NT.

This operation may take a long time on large hard disks, which may not be appropriate in some production environments.

RESOLUTION

A hotfix is available to modify Autochk so that you have 30 seconds at startup to choose not to run Autochk during the present startup. If you cancel Autochk, it is automatically rescheduled to run the next time you start Windows NT.

WARNING: Autochk runs because it has detected that the computer was not shut down properly or because it has detected problems with the file system. Preventing Autochk from running may cause additional file system problems to occur that can lead to data loss. Microsoft does not recommend disabling Autochk from running unless you have a full backup of the volume.

To work around this issue, obtain the hotfix described below, or wait for the next available service pack.

STATUS

A supported fix is now available, but has not been fully regression tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix.
