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
