Hi everyone,

I wanted to share a simple PowerShell script that you can use within Pulseway Automation to remotely eject any USB storage devices connected to a system. This can be helpful for security-conscious environments or in scenarios where USB usage needs to be tightly controlled.

Works well in combination with the Disable USB Storage Access script in the built in category.

 

The script uses Shell.Application to trigger the native "Eject" action for removable drives (DriveType = 2). Here's the version that loops through all mounted USB volumes:

✅ Works great in Pulseway automation tasks
💡 You can modify it to eject a specific drive letter if needed

powershell

# Eject all USB volumes using Shell.Application COM object
$Eject = New-Object -ComObject Shell.Application

# Get all removable (DriveType = 2) volumes with drive letters
$volumes = Get-WmiObject -Class Win32_Volume | Where-Object { $_.DriveType -eq 2 -and $_.DriveLetter }

foreach ($vol in $volumes) {
    Write-Host "Ejecting drive $($vol.DriveLetter)..."
    $Eject.NameSpace(17).ParseName($vol.DriveLetter).InvokeVerb("Eject")
}

 

Notes:

During my testing, I've seen that USB devices will not be removed if a process is running from the disks in question.
In other words, if there is a write/read process running, the disk is not ejected.

 

Let me know if you have questions or enhancements!

Hey @mx1m3 - This is amazing! Thank you so much for sharing with the community🤩

For remote troubleshooting and logging in Pulseway, is there a good PowerShell method to first identify and log the specific process (or processes) that are currently holding a file handle on a drive before the eject command is run?

Hey @Rhatake - Thanks for reaching out! Yes, you can use custom script include Sysinternals Handle.exe (from Microsoft) via PowerShell to identify and log.  Next you can create a PowerShell script under Automation > Automation hub > User Defined > Create Script. Either you can create a Task in the same page to schedule the script or run manually on multiple machines from Device > Device management > Selecting the machines > Action > Run Script. Refer to images😊
