    I am trying to execute the below given code, but its giving an error message
    get-wmiobject -class win32_logicaldisk -filter "deviceid=c:"

    random commandline

    Use Get-Help Get-WmiObject -Parameter filter for more info

    get-wmiobject -class win32_logicaldisk -filter "deviceid='c:'"

    Should be
    Get-WmiObject -Class Win32_LogicalDisk -Filter "DeviceId='C:'"

    When you create a filter the value you're testing has to be in quotes if it's a string value

    (Get-CimClass -ClassName Win32_LogicalDisk).CimClassProperties['DeviceId']

    Name : DeviceID
    Value :
    CimType : String
    Flags : Property, Key, ReadOnly, NullValue
    Qualifiers : {CIM_Key, read, key, MappingStrings...}
    ReferenceClassName :

    Same applies to Get-CimInstance
    Get-CimInstance -ClassName Win32_LogicalDisk -Filter "DeviceId='C:'"
