Specifies the list of drives to schedule for Autochk at the next reboot. The string syntax consists of the drive letter followed by a colon for the logical disk, for example: "C:"

The following VBScript and PowerShell samples schedule Autochk.exe to run against drive C the next time the computer reboots.


strComputer = "." 
Set objWMIService = GetObject("winmgmts:" _ 
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2") 
 
Set objDisk = objWMIService.Get("Win32_LogicalDisk")
