   * `type`: URL of the disk type resource describing which disk type to use to create the disk. Provide this when creating the disk.
 
-  * `erase_windows_vss_signature`: (Beta only) Specifies whether the disk restored from a source snapshot should erase Windows specific VSS signature.
-
   * `source_image`: The source image used to create this disk. If the source image is deleted, this field will not be set.  To create a disk with one of the public operating system images, specify the image by its family name. For example, specify family/debian-9 to use the latest Debian 9 image:  projects/debian-cloud/global/images/family/debian-9  Alternatively, use a specific version of a public operating system image:  projects/debian-cloud/global/images/debian-9-stretch-vYYYYMMDD  To create a disk with a private image that you created, specify the image name in the following format:  global/images/my-private-image  You can also specify a private image by its image family, which returns the latest version of the image in that family. Replace the image name with family/family-name:  global/images/family/my-private-family
 
   * `resource_policies`: (Beta only) Resource policies applied to this disk for automatic snapshot creations.
