[BUG] Remove-Containerdata.ps1 fails when encounters mounted vhd

[fimblecog]

Describe the bug
The script runs in its native form at first but then fails and kicks out when it encounters a VHD that is mounted.

To Reproduce
Have a user logged into a VDI desktop and run the script on their volume. When it comes to their vhd the script will fail and say that it can't identify a drive letter.

Expected behavior
I expect it to log that the disk is mounted and continue on.

Desktop (please complete the following information):

• OS: Windows Server 2016 Standard

Additional context
Here's how I got it to keep going past the failure.

I inserted a function that I retrieved from another script that may be one of yours. I modified it some to make it work though.

function checkFileStatus($FileInfo)
{

    try 
    {
        $fileStream = $FileInfo.Open( [System.IO.FileMode]::Open, [System.IO.FileAccess]::Read)
        $filestream.Close()
        return $false
    }
    catch
    {
        
        return $true
    }
}

Then I inserted the bold text below to screen for mounted containers

  # Step through each Container
    ForEach ($container in $Containers) {


        ****$locked = checkFileStatus($container)
        If ($locked -eq $true) {continue}****

I had the same issue. i used the following code instead of the Add-FSLDriverLetter module.

1. Comment out
   #$MountPath = Add-FslDriveLetter -Path $container.FullName -Passthru
2. Add the following code :
   $Disk = Mount-DiskImage -ImagePath $container.FullName -PassThru -NoDriveLetter -ErrorAction Stop | Get-Diskimage
   if ($Disk){
   set-partition -DiskNumber $Disk.Number -PartitionNumber 1 -NewDriveLetter Z -ErrorAction Stop
   $MountPath = "Z:"
   }else{$MountPath = $null
   }
