     Additional options for create and convert:
        -a       : (for use with -c only) adapter type (ide, buslogic or lsilogic)
        -s          : capacity of the virtual disk

        1                 : growable virtual disk split in 2Gb files
        2                 : preallocated virtual disk
        3                 : preallocated virtual disk split in 2Gb files

     The capacity can be specified in sectors, Kb, Mb or Gb.
     The acceptable ranges:
                           ide adapter : [100.0Mb, 950.0Gb]
                           scsi adapter: [100.0Mb, 950.0Gb]
        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:
