Get Disk - PowerShell


Get-Disk retrieves detailed information about physical and logical disk drives on the local and remote computers. It provides insights into properties such as disk size, type, file system, and health status. This command is useful for system administrators, storage engineers, and general users for managing and monitoring disk resources.


Get-Disk [[-ComputerName] <String>] [-Exclude <String[]>] [-Include <String[]>]
[-Credential <PSCredential>] [-Filter <String>] [-ErrorVariable <String>]
[-WarningVariable <String>] [-OutVariable <String>] [-OutBuffer <Int>]


  • -ComputerName: Specifies the remote computer to retrieve disk information from.
  • -Exclude: Excludes specific disks from the results based on name or number.
  • -Include: Includes only specified disks in the results based on name or number.
  • -Credential: Provides credentials for accessing remote disks.
  • -Filter: Filters the results using WMI queries. See about_Filters for more information.

Example 1: Get information about all disks on the local computer


Example 2: Get information about a specific disk by number

Get-Disk -Number 2

Example 3: Get information about disks on a remote computer

Common Issues

  • Disks not appearing in results: Ensure that the disks are connected and visible to the operating system.
  • Access denied errors: Verify that you have sufficient permissions to access the disks on the specified computer.
  • Incorrect disk information: Update the WMI and CIM providers to ensure accurate disk information.


Get-Disk can be combined with other PowerShell commands to perform advanced tasks, such as:

  • Get-Partition: Retrieves information about partitions on a disk.
  • New-Volume: Creates new volumes on a disk.
  • Initialize-Disk: Initializes a disk and makes it available for use.
