        ex 1: vmware-vdiskmanager.exe -c -s 850Mb -a ide -t 0 myIdeDisk.vmdk
        ex 2: vmware-vdiskmanager.exe -d myDisk.vmdk
        ex 3: vmware-vdiskmanager.exe -r sourceDisk.vmdk -t 0 destinationDisk.vmdk
        ex 4: vmware-vdiskmanager.exe -x 36Gb myDisk.vmdk
        ex 5: vmware-vdiskmanager.exe -n sourceName.vmdk destinationName.vmdk
        ex 6: vmware-vdiskmanager.exe -k myDisk.vmdk
        ex 7: vmware-vdiskmanager.exe -p m:
