Filtering Get Psdrive To All Local Drives

Recently I needed to filter the return of get-psdrive to return all of my local hard drives. I didn’t want to accidentally start operating on floppies, CDROM’s and more importantly, network drives. There are a couple of ways to do this but I found the most straight forward is to combine the WMI data with get-psdrive.

E:\temp> get-wmiobject win32_volume | ? { $_.DriveType -eq 3 } | % { get-
psdrive  
$_.DriveLetter[0] }

Name       Provider      Root
CurrentLocation  
\----       \--------      \----
\---------------  
C          FileSystem    C:\
...nfig\PowerShell  
E          FileSystem    E:\
temp

DriveType is a property of the Win32_Volume structure which enumerates the type of drive. The value 3 stands for Local Disk. Below is the full list of values.

0 - Unknown  
1 - No Root Directory  
2 - Removable Disk  
3 - Local Disk  
4 - Network Drive  
5 - Compact Disk  
6 - RAM Disk
