Get the drive letter of USB drive in PowerShell

Question

I\'ve seen articles in C# and some other languages that explain how to achieve what I\'m looking for but I don\'t know how to convert them.

• The following lin

Answer 1

Beginning with PowerShell v3.0, Microsoft introduce the Get-Cim* commands which make this easier than the ugliness of the Get-WmiObject ASSOCIATORS query method:

Get-CimInstance -Class Win32_DiskDrive -Filter 'InterfaceType = "USB"' -KeyOnly | 
    Get-CimAssociatedInstance -ResultClassName Win32_DiskPartition -KeyOnly |
    Get-CimAssociatedInstance -ResultClassName Win32_LogicalDisk |
    Format-List *

Or:

Get-CimInstance -Class Win32_DiskDrive -Filter 'InterfaceType = "USB"' -KeyOnly |
    Get-CimAssociatedInstance -Association Win32_DiskDriveToDiskPartition -KeyOnly |
    Get-CimAssociatedInstance -Association Win32_LogicalDiskToPartition |
    Format-List *

The above commands are equivalent.

Answer 2

I know the subject has been dropped for a while, but since it's something I come back to pretty often, I thought I'd update things a bit.

If using Windows 7 and above, a much simpler solution would be:

Get-WmiObject Win32_Volume -Filter "DriveType='2'"

And if you want to avoid magic numbers:

Get-WmiObject Win32_Volume -Filter ("DriveType={0}" -f [int][System.IO.DriveType]::Removable)

Answer 3

Try:

gwmi win32_diskdrive | ?{$_.interfacetype -eq "USB"} | %{gwmi -Query "ASSOCIATORS OF {Win32_DiskDrive.DeviceID=`"$($_.DeviceID.replace('\','\\'))`"} WHERE AssocClass = Win32_DiskDriveToDiskPartition"} |  %{gwmi -Query "ASSOCIATORS OF {Win32_DiskPartition.DeviceID=`"$($_.DeviceID)`"} WHERE AssocClass = Win32_LogicalDiskToPartition"} | %{$_.deviceid}

Tested with one and more than one USB device plugged-in.

Answer 4

get-volume | where drivetype -eq removable | foreach driveletter
