Calling ChkDsk via WMI
Some WMI classes contain methods that you can call to invoke some action. For example, the next line initiates a disk check on drive D:
([wmi]"Win32_LogicalDisk='D:'").Chkdsk($true, $false, $false, $false, $false, $true).ReturnValue
Make sure you have administrator privileges or else you receive a return value of 2 which corresponds to "Access Denied".
If you'd like to know what the arguments are for, ask for a method signature:
([wmi]"Win32_LogicalDisk='D:'").Chkdsk
