[list] List all devices, partitions and volumes in Powershell

I have multiple volumes (as nearly everybody nowadays): on Windows they end up specified as C:, D: and so on. How do I list these all like on a Unix machine with "ls /mnt/" with Powershell?

Run command:

Get-PsDrive -PsProvider FileSystem

For more info see:

• PsDrive Documentation

• PSProvider Documentation

Firstly, on Unix you use mount, not ls /mnt: many things are not mounted in /mnt.

Anyhow, there's the mountvol DOS command, which continues to work in Powershell, and there's the Powershell-specific Get-PSDrive.

On Windows Powershell:

Get-PSDrive 
[System.IO.DriveInfo]::getdrives()
wmic diskdrive
wmic volume

Also the utility dskwipe: http://smithii.com/dskwipe

dskwipe.exe -l

We have multiple volumes per drive (some are mounted on subdirectories on the drive). This code shows a list of the mount points and volume labels. Obviously you can also extract free space and so on:

gwmi win32_volume|where-object {$_.filesystem -match "ntfs"}|sort {$_.name} |foreach-object {
  echo "$(echo $_.name) [$(echo $_.label)]"
}

This is pretty old, but I found following worth noting:

PS N:\> (measure-command {Get-WmiObject -Class Win32_LogicalDisk|select -property deviceid|%{$_.deviceid}|out-host}).totalmilliseconds
...
928.7403
PS N:\> (measure-command {gdr -psprovider 'filesystem'|%{$_.name}|out-host}).totalmilliseconds
...
169.474

Without filtering properties, on my test system, 4319.4196ms to 1777.7237ms. Unless I need a PS-Drive object returned, I'll stick with WMI.

EDIT: I think we have a winner: PS N:> (measure-command {[System.IO.DriveInfo]::getdrives()|%{$_.name}|out-host}).to??talmilliseconds 110.9819

Get-Volume

You will get: DriveLetter, FileSystemLabel, FileSystem, DriveType, HealthStatus, SizeRemaining and Size.

Though this isn't 'powershell' specific... you can easily list the drives and partitions using diskpart, list volume

PS C:\Dev> diskpart

Microsoft DiskPart version 6.1.7601

On computer: Box

DISKPART> list volume

Volume ###  Ltr  Label        Fs     Type        Size     Status     Info
----------  ---  -----------  -----  ----------  -------  ---------  --------
Volume 0     D                       DVD-ROM         0 B  No Media
Volume 1         C = System   NTFS   Partition    100 MB  Healthy    System
Volume 2     G   C = Box      NTFS   Partition    244 GB  Healthy    Boot
Volume 3     H   D = Data     NTFS   Partition    687 GB  Healthy
Volume 4     E   System Rese  NTFS   Partition    100 MB  Healthy

You can also do it on the CLI with

net use
