PowerTip: List Physical Drives with PowerShell

Summary: Use Windows PowerShell to list physical drives.

Hey, Scripting Guy! Question How can I use Windows PowerShell to get a list of physical drives?

Hey, Scripting Guy! Answer Use Get-WMIObject, query win32_logicaldisk, and filter with the DriveType property:

GET-WMIOBJECT –query “SELECT * from win32_logicaldisk where DriveType = ‘3’”

To check the drives on a remote computer, add the –ComputerName parameter.
For example, to list all physical drives and their free space on a machine called “ContosoWS1”:

GET-WMIOBJECT –query “SELECT * from win32_logicaldisk where DriveType = ‘3’”
–computername “ContosoWS1”

  • For me, on Windows 8 Enterprise, i don't need the ' around the drivetype.

    These commandlets are OK for me:

    GET-WMIOBJECT –query “SELECT * from win32_logicaldisk where DriveType = 3”

    GET-WMIOBJECT –query “SELECT * from win32_logicaldisk where DriveType = 3”

    –computername “ContosoWS1”

    Actually it works that way in Windows 7 as well.  It's just a force of habit I have when working with WMI queries to isolate the results in the query.

    Love that you're rocking it with PowerShell!

  • Strictly speaking, this command doesn't list physical drives at all.  It lists logical drives located on whatever Windows considers to be a "Local Disk" (which, oddly enough, includes some external USB drives, even though you might think those should be categorized as Removable).

    There can be many Win32_LogicalDisk objects associated with a single physical disk, if you have multiple partitions or volumes on that disk.

  • Quote are always soptional aroung numeric and Booleans.

    Prop1=True

    Prop1='True'

    Prop2=1

    Prop2='1'

    Strings always require quotes.  This is also true in almost all programming systems including VBScript and PowerShell.

  • @David

    You are correct in that it accesses the logical drive letters.   If you wish to access the PhysicalDisks leverage the win32_diskdrive within WMI.  The advantage I find with LogicalDisk is the ability to get the drive letter.

    Good tip on working with WMI Queries :)

  • Caution:  the snippet contains "smart" quotes so can't be literally copy-pasted.  You need to edit the apos and quot chars after ^C  ^V

  • Get-PSDrive

  • I am trying to get a list which contains drives of multiple servers and I wrote a script. But it looks like it is not taking multiple computers. Script is below get-WmiObject win32_logicaldisk -ComputerName (get-content d:\scripts\sea.txt) | Format-table -Property @{name='Free space(in GB)'; e={$_.Freespace/1GB}; align='right'; formatstring='N2'}, @{name='Total Size (in GB)'; e={$_.size/1GB}; align='right'; formatstring='N2'} -autosize >>D:\Scripts\Test.csv Please suggest alternatives.

  • Hi, I hope you can help. I need a good way to show the mapping between a iscsi lun to disk
    If I run Get-iSCSISession | Get-Disk | where {$_.operationalstatus -eq "online"} | Ft -autosize -wrap, I can see the disk number but the name isn't detailed.
    Number Friendly Name OperationalStatus Total Size Partition Style
    15 LEFTHAND iSCSIDisk Multi-Path Disk Device Online 123 GB MBR

    I need the "TargetNodeAddress : iqn.2003-10.com.lefthandnetworks:avalonprod:71724:on-dc01-av" with the Lun or disk ID

    Any help is awesome!

  • I can not recollect ever having working code from the scripting guys
