VMware Workstation's clone feature only produces thin disk output (1017514)

Resolution

When using the Clone feature in VMware Workstation, the resulting virtual disk always has a thin provisioned disk format. There is currently no option from within the Workstation user interface to force the resulting disk from a clone operation to be any other format.
 
You can, however, use the Virtual Disk Manager utility (which is packaged with both the Windows and Linux versions of VMware Workstation) to clone a virtual machine and specify the format of the resulting virtual disk.
 
Caution: Changes made to a virtual disk when using the Virtual Disk Manager utility are irreversible. VMware strongly recommends that the virtual disk files are backed up fully before performing any action with the Virtual Disk Manager Utility.
 
To clone a virtual disk while ensuring that the resulting virtual disk is a pre-allocated or Thick disk using the Virtual Disk Manager utility on your Windows-based installation of VMware Workstation:
  1. Click Start > Run.
  2. To open a command prompt, type cmd, then click OK.
  3. Navigate into the VMware Workstation installation directory. The default installation path is typically C:\Program Files\VMware\VMware Workstation.
  4. The Virtual Disk Manager utility is identified as vmware-vdiskmanager.exe

    Note: To view the utility's manual, run the command vmware-vdiskmanager.exe /?.
      
  5. The syntax for cloning a virtual disk into a new pre-allocated or Thick format disk is:

    vmware-vdiskmanager.exe -r sourceDisk.vmdk -t 2 destinationDisk.vmdk.
To clone a virtual disk while ensuring that the resulting virtual disk is a pre-allocated or Thick disk using the Virtual Disk Manager utility on your Linux-based installation of VMware Workstation:
  1. Open the Terminal. For more information, see Opening a command or shell prompt (1003892).
  2. Execute the Virtual Disk Manager utility with the command:

    vmware-vdiskmanager

    Note: To view the utility's manual, run the command vmware-vdiskmanager --help.
     
  3. The syntax for cloning a virtual disk into a new pre-allocated or Thick format disk is:

    vmware-vdiskmanager -r sourceDisk.vmdk -t 2 destinationDisk.vmdk
