Hi

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

June 10, 2016 at 12:44 pm

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:'"
