How to get only physical drives?

My example code is below. I don't need drives like the cd rom and what not.

$drive = Get-WmiObject Win32_LogicalDisk -ComputerName $compName | ForEach-Object -Process {$_.DeviceID}

You might find the output of Get-WMIObject -Class Win32_LogicalDisk -Property * | Select-Object -First 1 | Get-Member to be both interesting and useful. – Jeff Zeitlin – 2017-06-26T15:01:51.540

if you have PowerShell v3+ and for local only, just use get-physicaldisk – SimonS – 2017-06-26T15:01:55.353

Two methods using interface type or media type

First option interfacetype,

gwmi win32_diskdrive | ?{$_.interfacetype -eq "IDE" -or $_.interfacetype -eq "SCSI" }

Interface type of physical disk drive.

The values are:

SCSI
HDC
IDE
USB
1394

Second option mediatype

gwmi win32_diskdrive | ?{$_.mediatype -eq "Fixed hard disk media"}

Possible values are:

External hard disk media
Removable media ("Removable media other than floppy")
Fixed hard disk ("Fixed hard disk media")
Unknown ("Format is unknown")

to get phsyical drive

gwmi win32_diskdrive | ?{$_.mediatype -eq "Fixed hard disk media"} | % -Process {$_.DeviceID}

to get logical drive

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

If you want only physical drives it's as easy as

PS>  Get-PhysicalDisk
FriendlyName               SerialNumber         MediaType   CanPool OperationalStatus HealthStatus Usage           Size
------------               ------------         ---------   ------- ----------------- ------------ -----           ----
Generic USB  SD Reader     x                    Unspecified False   OK                Healthy      Auto-Select 14.49 GB
Samsung SSD 840 PRO Series xxxxxxxxxxxxxxx      SSD         True    OK                Healthy      Auto-Select ...47 GB
ST2000DL003-9VT166         xxxxxxxx             HDD         False   OK                Healthy      Auto-Select  1.82 TB
ASMT 2105                  xxxxxxxxxxxxxxxxxxxx Unspecified False   OK                Healthy      Auto-Select ...51 GB

if you want the chain of associators this could help

$diskdrive = gwmi win32_diskdrive

foreach($drive in $diskdrive){
    out-host -InputObject "`nDrive: deviceid-$($drive.deviceid.substring(4)) Model - $($drive.model)"
    ##partition
    $partitions = gwmi -Query "ASSOCIATORS OF {Win32_DiskDrive.DeviceID=`"$($drive.DeviceID.replace('\','\\'))`"} WHERE AssocClass = Win32_DiskDriveToDiskPartition"
    foreach($part in $partitions){
        Out-Host -InputObject "`tPartition: $($part.name)"
        $vols = gwmi -Query "ASSOCIATORS OF {Win32_DiskPartition.DeviceID=`"$($part.DeviceID)`"} WHERE AssocClass = Win32_LogicalDiskToPartition"
        foreach($vol in $vols){
            out-host -InputObject "`t`t$($vol.name)"
        }
    }
}

Sample Output

Drive: deviceid-PHYSICALDRIVE0 Model - ST2000DL003-9VT166
        Partition: Disk #0, Partition #0
                D:

Drive: deviceid-PHYSICALDRIVE1 Model - Samsung SSD 840 PRO Series
        Partition: Disk #1, Partition #0
                H:
        Partition: Disk #1, Partition #1
                C:
        Partition: Disk #1, Partition #2

Drive: deviceid-PHYSICALDRIVE2 Model - Generic USB  SD Reader USB Device
        Partition: Disk #2, Partition #0
                I:

Drive: deviceid-PHYSICALDRIVE3 Model - ASMT 2105 USB Device
        Partition: Disk #3, Partition #0
