Chkdsk is a native Windows NT tool that can determine the extent of fileand file system corruption. If Chkdsk is to run in write-mode to attempt toremedy corruption, in most cases, there will be locked files and itrequires restarting to have exclusive access to the partition orpartitions. This process can be automated and requires no userintervention. Usually, a user needs to press "y" to schedule Chkdsk to runin write-mode on the next restart; however, this process can be automatedas follows:
Create a batch file and then disseminate it to the preferred system orsystems:
@echo off echo y|chkdsk [target drive, i.e. D:] /f/r rem sleep 3600 rem c:\utils\shutdown.exe /l /r /y /t:6
The last two lines are optional. Sleep.exe and Shutdown.exe are from theMicrosoft Windows NT Server 4.0 Resource Kit. "Sleep 3600" causes the system to wait for 60 minutes before proceeding to the next line in the batch file. Shutdown.exe is then called to shut down and restart the target system. If Shutdown.exe is not called, and the drive could not be locked for exclusive use, Chkdsk runs the next time you manually restart the target system.
In those cases where you would like Chkdsk, or the above batch file, to bescheduled to run on specific days or times, AT Scheduler (command-lineinterface) or WinAT Scheduler (GUI-based interface that has addedfunctionality) can be used. You can find WinAT in the Microsoft Windows NT Server 4.0 Resource Kit.
