If the destination is smaller, then the As is option of cloning will be unavailable and proportional 
resizing of the source disk volumes will be mandatory. The program analyzes the target disk to 
establish whether its size will be sufficient to hold all the data from the source disk without any loss. 
If such transfer with proportional resizing of the source disk volumes is possible, but without any data 
loss , then the user will be allowed to proceed. If due to the size limitations safe transfer of all the 
source disk data to the target disk is impossible even with the proportional resizing of the volumes, 
then the Clone basic disk operation will be impossible and the user will not be able to continue. 
If you are about to clone a disk comprising of a system volume, pay attention to the Advanced 
options
By clicking Finish, you'll add the pending operation of the disk cloning. 
(To finish the added operation you will have to commit (p. 271) it. Exiting the program without 
committing the pending operations will effectively cancel them.) 
Using advanced options 
When cloning a disk comprising of a system volume, you need to retain an operating system 
bootability on the target disk volume. It means that the operating system must have the system 
volume information (e.g. volume letter) matched with the disk NT signature, which is kept in the MBR 
disk record. But two disks with the same NT signature cannot work properly under one operating 
system. 
If there are two disks having the same NT signature and comprising of a system volume on a machine, at the 
startup the operating system runs from the first disk, discovers the same signature on the second one, 
automatically generates a new unique NT signature and assigns it to the second disk. As a result, all the volumes 
on the second disk will lose their letters, all paths will be invalid on the disk, and programs won't find their files. 
The operating system on that disk will be unbootable. 
You have the following two alternatives to retain system bootability on the target disk volume: 
1.  Copy NT signature – to provide the target disk with the source disk NT signature matched with 
the Registry keys also copied on the target disk. 
2.  Leave NT signature – to keep the old target disk signature and update the operating system 
according to the signature. 
If you need to copy the NT signature: 
1.  Select the Copy NT signature check box. You receive the warning: “If there is an operating system 
on the hard disk, uninstall either the source or the target hard disk drive from your machine prior 
to starting the machine again. Otherwise, the OS will start from the first of the two, and the OS 
on the second disk will become unbootable.” The Turn off the machine after the cloning 
operation
 check box is selected and disabled automatically. 
2.  Click Finish to add the pending operation. 
3.  Click Commit on the toolbar and then click Proceed in the Pending Operations window. 
4.  Wait until the task is finished. 
5.  Wait until the machine is turned off. 
6.  Disconnect either the source or the target hard disk drive from the machine. 
7.  Start up the machine.
