In digital forensics, analyst do disk imaging to collect information before analysis. Then why they don't use 'copy'? What is difference between disk imaging and copy?
So this is more of a language question than a programming question. A disk image is a computer file that represents the contents of a physical volume (usually). So when analysts create a disk image they are, in fact, copying data from the disk to a file.
So to creating a disk image is probably a type of copying, but they could also copy individual files. Copying could be seen as a technique, where a disk image could be seen as a type of file that is a copy of a physical drive.

Consider the Operating System is installed on C drive. And what is the file type used to save passwords.
Windows logon passwords are never stored in their original form and always encrypted. They are stored in C:/WINDOWS/SYSTEM32/config (Assuming windows installed in C drive) folder. Passwords are stored in files called sam files. But they are hashed and so encrypted.
For passwords other than windows passwords, their storage and encryption depend on the application that created those passwords. They might reside on your computer or on a remote location.

My problem is convert GPT volume not disk. I found some solutions but they are all about how to convert disk. On my windows 8, it has disk 0. disk 0 has 7 volumes. I just want to convert one volume in disk 0 . How can I do this?
I find a solution. I delete the disks with Gparted. I download from http://gparted.org/download.php and copy to dvd as bootable. I boot the PC and divide the partitions as NTFS. That's all.

Is it possible to have two "Current Folder" windows open in MATLAB?
I have two folders a long way away from one another in the folder tree and need to keep files in the same place as the are referred to by other software.
I should add that I am in the process of importing specific files from each one and cannot do all of one folder at once.
Short answer: no. You need to use commands like cd to change from one folder to another for importing files, or add both folders to your MATLAB path using addpath. The latter has the advantage of referring to any file in these folders without having to specify in which folder they are located.

I am learning Operating System but these words really confused me , i tried to search on the internet but couldnt find the exact difference between them?? can anybody help me out and clear my confusion??
Primary storage (also main memory and physical memory) are generally used interchangeably to refer to the memory that is attached directly to the processor.
Secondary storage is storage that is not directly connected to the CPU. The most common case of secondary storage is the hard disk.
You say searched on the internet without finding an explanation, however wikipedia seems to have a lot to say about computer storage http://en.wikipedia.org/wiki/Computer_data_storage

I need to clone/ghost a GE protected hard drive, but I am running into various issues. Norton Ghost seems to just freeze up, XXClone puts up strange errors. I realize the entire drive is encrypted, but would that make a difference to a cloning software?
Anybody have any experience with this?
Under Linux you can use the dd command to clone data from one drive to another.
If you don't have a machine running Linux, you can download a bootable CD from e.g. http://www.sysresccd.org/Main_Page which will have dd and other useful commands for dealing with hard drives and data recovery.
