 When you delete a virtual machine (VM) in Azure, by default, any disks that are attached to the VM aren't deleted. This feature helps to prevent data loss due to the unintentional deletion of VMs. After a VM is deleted, you will continue to pay for unattached disks. This article shows you how to find and delete any unattached disks and reduce unnecessary costs.

 ## Managed disks: Find and delete unattached disks
 
 The following script looks for unattached [managed disks](../managed-disks-overview.md) by examining the value of the **ManagedBy** property. When a managed disk is attached to a VM, the **ManagedBy** property contains the resource ID of the VM. When a managed disk is unattached, the **ManagedBy** property is null. The script examines all the managed disks in an Azure subscription. When the script locates a managed disk with the **ManagedBy** property set to null, the script determines that the disk is unattached.
