Powershell script to get disk information including block size

This script can be downloaded from the Microsoft Technet Gallery. It contains the Get-SBDisk function which takes one parameter as input being one or more computer names or IP addresses. It return s a PowerShell object for each fixed disk of each input computer.

To see the inline help and example:

help Get-SBDisk -ShowWindow


This script takes advantage of this function and collects disk information on all computers in the current AD domain (without the need to use ActiveDirectory PowerShell module):

$adsi = [adsisearcher]"objectcategory=computer"
$adsi.SearchRoot = "LDAP://dc=$($env:USERDNSDOMAIN.replace('.',',dc='))"
$adsi.filter = "(&(objectClass=Computer)(!userAccountControl:1.2.840.113556.1.4.803:=2))" # enabled computers
$adsi.PageSize = 1000000 
$EnabledADComputers = $adsi.FindAll()
$EnabledADComputerNames = @()
$EnabledADComputerNames += $EnabledADComputers | % { $ } # List of the names of enabled computers from AD
$i = 0
$DiskInfo = @()
$EnabledADComputerNames | % {
   Write-Progress -Activity "Checking disks on computer $_" -Status "$i of $($EnabledADComputerNames.Count)"
   $DiskInfo += Get-SBDisk $_ -Verbose
$DiskInfo | FT -a # output disk information to console
$DiskInfo | Out-GridView # Output disk information to ISE grid view
$DiskInfo | Export-Csv .\DiskInfo.csv -NoType # Save disk information to CSV

"Checked $($EnabledADComputerNames.Count) computers in AD"
"Found $(($DiskInfo | % { $_.ComputerName } | select -Unique).Count) reachable computers"
"$($DiskInfo.Count) disks checked"


This is formatted to work with PS version 2.

During the script run you may see progress similar to:


and output similar to:


To view a list of disks with less than 20% free space:

"Disks with less than 20% free space"
$DiskInfo | 
    where { $_.'Free(%)' -lt 20 -and $_.'Free(%)' -ne 100 } | 
       sort 'Free(%)' | FT -a




PowerShell script to report on computer inventory

Back in October of 2014 I responded to a TechNet Script Center Repository Request


The script I wrote back then looked like:


Based on user feedback I decided to update this script. Version 2 is now online. Enhancements in version 2 include:

  • Powershell 2.0 compatibility (Windows 7 and Server 2008 native, Windows 2003 and Windows XP possible)
  • Script version 2 is backward compatible with script version 1 in the sense that example are provided to use script v2 to produce same output as script v1
  • Both scripts return output as a PS Object which lends itself handy to further automation
  • Added -Verbose output, removed ‘log’ function
  • Added more information for computer object:
    •  Manufacturer – example : Microsoft Corporation
    • OSCaption – example : Microsoft Windows 7 Professional
    • VirtualMachine  : True or False
    • OSArchitecture – example : 64-bit

Example 1


The script returns a PS object similar to:


Example 2

.\Ping-Report-v2.ps1 -ComputerName $env:COMPUTERNAME,bla1,p-2012r2-sb1

Possible output:


This example shows output when a computer is down, and when the script is run under a user context that has no permission/access to query the target computer(s)

Example 3

The same can be done reading the computer list from a CVS file as in:

Import-Csv .\Computerlist.csv | 
  % { .\Ping-Report-v2.ps1 $_.ComputerName }

The input CSV file may look like:


Example 4

The output can be exported to CSV to file as in:

Import-Csv .\Computerlist.csv | 
  % { .\Ping-Report-v2.ps1 $_.ComputerName } | 
    select ComputerName, Status, OSCaption, VirtualMachine, IPAddress |
      Export-Csv z:report1.csv -NoType


Example 5

.\Ping-Report-v2.ps1 V-WIN7PROX64,bla1,V-WIN7PROX64,p-2012r2-sb1 | 
    select ComputerName, Status, OSCaption, VirtualMachine, IPAddress | FT -a
