Deleting multiple unattached azure disks in bulk

My question is broken into two sections, related to Azure disks that are unattached/ no owner. 1s question: Besides using the Azure portal to check which disks have no owner associated with them, is there another way I can check or run a script for secondary sanity checks to verify which disks are no longer in use? 2. Question: Once I populate the Disk name in an Excel spreadsheet, how I can delete it in bulk so I don't have to go through the portal one by one?

    Hello Razzi,
    I think you might find this article useful.
    https://learn.microsoft.com/en-us/azure/virtual-machines/windows/find-unattached-disks#managed-disks-find-and-delete-unattached-disks

    First, after connecting with powershell to your Azure instance, run the script by setting the deleteUnattachedDisks variable to 0. This action lets you find and view all the unattached managed disks.
    After you review all the unattached disks, run the script again and set the deleteUnattachedDisks variable to 1. This action lets you delete all the unattached managed disks.

    # Set deleteUnattachedDisks=1 if you want to delete unattached Managed Disks  
    # Set deleteUnattachedDisks=0 if you want to see the Id of the unattached Managed Disks  
    $deleteUnattachedDisks=0  
    $managedDisks = Get-AzDisk  
    foreach ($md in $managedDisks) {  
        # ManagedBy property stores the Id of the VM to which Managed Disk is attached to  
        # If ManagedBy property is $null then it means that the Managed Disk is not attached to a VM  
        if($md.ManagedBy -eq $null){  
            if($deleteUnattachedDisks -eq 1){  
                Write-Host "Deleting unattached Managed Disk with Id: $($md.Id)"  
                $md | Remove-AzDisk -Force  
                Write-Host "Deleted unattached Managed Disk with Id: $($md.Id) "  
            }else{  
                $md.Id  
            }  
        }  
     }  
    

    Hope this will help.

    Best

    @Pietro Visentin This link is definitely useful for deleting every disk that is not attached, but I want to be specific in the deletion, that is why I am trying to find a way to have a script read from a csv where I am specifying a few disks I want to delete in bulk.
