VMDK Properties

I have an array of disks on a VM and I want to create a property set of Hard Disk Name and Hard Disk UUID.  But when I print out the properties set it only prints out the last Hard Disk Information Below is my code:

for each (var vmdkInfo in vmdkDisks){

input = vmdkDisks (array of vm disks (lets say 3))

var vmdkProperties = new Properties ();

  vmdkProperties.put("Hard Disk Name", vmdkInfo.deviceInfo.label);

  vmdkProperties.put("VMDK UUID", vmdkInfo.backing.uuid);

  }

System.log(vmdkProperties);

current output
