How to find a volume GUID and list the volume GUIDs for each disk. –

Windows uses drive letters and labels (or both) to make it easier for the end user to identify partitions (volumes) on installed drives.

Instead, the operating system uses a Globally Unique Identifier (GUID) that uniquely identifies each volume (partition) for internal purposes. This is because it is difficult to identify certain volumes using only letters and disk labels, and also some disk partitions (such as “System” and “Recovery”) are not mapped to letters.

A volume GUID is a unique folder name that is assigned when you first attach a folder to the operating system and does not change even if the drive letter of the attached folder changes.

Volume GUID path “has the form”\\?\Voice{GUID}\“, where GUID a globally unique identifier (GUID) that identifies the volume. *

* e.g \\?\Top{3558506b-6ae4-11eb-8698-806e6f6e6963}\

In this tutorial, you’ll learn how to find the GUIDs of all the volumes on your system and how to determine which physical drive each Volume GUID is located on (if you have two or more physical drives). *

*Note: Open if you want to sign a GUID partition table (GPT) identifier or a physical disk master record (MBR). Command line as administrator and issue these commands in order:

  • disk partition
  • list disk
  • select the disk number
  • unique disc

How to find Volume GUID and view all volume GUIDs for each disk. *

*Note: You can use method-1 or method-2 below to find GUID of all folders. Note, however, that these methods do not indicate which drive each GUID folder resides on when there are multiple physical drives. If you want to know this information, use the instructions in method 3.

  1. Find the Volume GUID from the command line.
  2. Find the Volume GUID from PowerShell.
  3. Find the volume GUIDs for each disk.

Method 1. View all Volume GUIDs in Windows with the MOUNTVOL command.

The easiest way to see all the volume GUIDs on your system is to run the “mountvol” command at the command line.

*Note: The “mountvol” command is used to create, delete, or register a volume mount point. But if you give the command with any argument, it will list all Volume GUIDs.

Method 2. View volume GUIDs using PowerShell.

The second way to find the GUID of all the folders on your system is to use the following PowerShell command: *

View GUID Poersshell volume

*Note: You can also use the following command to display volume and free space information:

  • GWMI -namespace root\cimv2 -class win32_volume | FL – Property Label, DriveLetter, Device ID, System Size, Capacity, Free Space

Method 3. List volume GUIDs for each disk.

The above methods will help you see the GUID code of each volume on your system, but they will not help you determine which physical drive each volume is mounted on when the system has multiple hard drives and the volumes do not exist. drive letter (for example, the “System” or “Recovery” folder does not have a drive letter).

Since (as far as I know) Windows doesn’t offer a single command to get the physical location of each Volume GUID on one or more disks (on which disk the volume GUIDs are located), I use the DiskExt utility from Sysinternals to do this. task:

1. Download DiskExt and extract to a folder.

2. Open the extracted “DiskExt” folder and copy its path to the clipboard.

3. It’s open Command line as administrator.

4. Type in the command line window CDpress the button empty space once and click CTRL + V to paste the copied path. Click when done Enter.

5. Then issue this command and click Enter.

6. After running the command, you will see all the Volume GUIDs on your system and what disk each one is located on (eg Disk 0, Disk 1, etc.).
