Combine `Get-Disk` info and `LogicalDisk` info in PowerShell?

You need to query several WMI classes to get all information you want.

• Win32_DiskDrive gives you information about the physical disks.
• Win32_DiskPartition gives you information about the partitions on the physical disks.
• Win32_LogicalDisk gives you information about the filesystems inside the partitions.

Partitions can be mapped to their disks using the Win32_DiskDriveToDiskPartition class, and drives can be mapped to their partitions via the Win32_LogicalDiskToPartition class.

Get-WmiObject Win32_DiskDrive | ForEach-Object {  $disk = $_  $partitions = "ASSOCIATORS OF " +                "{Win32_DiskDrive.DeviceID='$($disk.DeviceID)'} " +                "WHERE AssocClass = Win32_DiskDriveToDiskPartition"  Get-WmiObject -Query $partitions | ForEach-Object {    $partition = $_    $drives = "ASSOCIATORS OF " +              "{Win32_DiskPartition.DeviceID='$($partition.DeviceID)'} " +              "WHERE AssocClass = Win32_LogicalDiskToPartition"    Get-WmiObject -Query $drives | ForEach-Object {      New-Object -Type PSCustomObject -Property @{        Disk        = $disk.DeviceID        DiskSize    = $disk.Size        DiskModel   = $disk.Model        Partition   = $partition.Name        RawSize     = $partition.Size        DriveLetter = $_.DeviceID        VolumeName  = $_.VolumeName        Size        = $_.Size        FreeSpace   = $_.FreeSpace      }    }  }}

How about like this...

Get-CimInstance Win32_Diskdrive -PipelineVariable disk |Get-CimAssociatedInstance -ResultClassName Win32_DiskPartition -PipelineVariable partition |Get-CimAssociatedInstance -ResultClassName Win32_LogicalDisk |Select-Object @{n='Disk';e={$disk.deviceid}},@{n='DiskSize';e={$disk.size}},@{n='DiskModel';e={$disk.model}},@{n='Partition';e={$partition.name}},@{n='RawSize';e={$partition.size}},@{n='DriveLetter';e={$_.DeviceID}},VolumeName,Size,FreeSpace

Output:

Inspired js2010's answer, with some enhancements:

For instance, the Manufacturer field seems to have some a placeholder value when retrieved from the Win32_DiskDrive instance, but has the proper value when using the Get-Disk commandlet.

function Get-Drive {  foreach($disk in Get-CimInstance Win32_Diskdrive) {    $diskMetadata = Get-Disk | Where-Object { $_.Number -eq $disk.Index } | Select-Object -First 1    $partitions = Get-CimAssociatedInstance -ResultClassName Win32_DiskPartition -InputObject $disk    foreach($partition in $partitions) {      $drives = Get-CimAssociatedInstance -ResultClassName Win32_LogicalDisk -InputObject $partition      foreach($drive in $drives) {        $totalSpace = [math]::Round($drive.Size / 1GB, 3)        $freeSpace  = [math]::Round($drive.FreeSpace / 1GB, 3)        $usedSpace  = [math]::Round($totalSpace - $freeSpace, 3)        $volume     = Get-Volume |                      Where-Object { $_.DriveLetter -eq $drive.DeviceID.Trim(":") } |                      Select-Object -First 1        [PSCustomObject] @{                            DriveLetter   = $drive.DeviceID                            Number        = $disk.Index                            Label         = $volume.FileSystemLabel                            Manufacturer  = $diskMetadata.Manufacturer                            Model         = $diskMetadata.Model                            SerialNumber  = $diskMetadata.SerialNumber.Trim()                             Name          = $disk.Caption                            FileSystem    = $volume.FileSystem                            PartitionKind = $diskMetadata.PartitionStyle                            TotalSpace    = $totalSpace                            FreeSpace     = $freeSpace                            UsedSpace     = $usedSpace                            Drive         = $drive                            Partition     = $partition                            Disk          = $disk        }      }    }  }}           

Example Usages:

Get-Drive | Format-ListGet-Drive | Where-Object { $_.DriveLetter -eq 'G:' }

Output:
