General Terms and Definitions

To simplify working with O&O DiskImage, certain terms will be explained in the following chapters:

Drive/Partition

A drive is a reserved area of the hard disk. Multiple drives can be found on a hard disk. In the following text, the

term “drive” will be used to depict (single) partitions as well as logical drives in extended partitions and volumes.

Drives are used, for example, to separate documents from programs. A division in two partitions has become gen-

erally accepted:

l Drive C: for operating systems and programs

l Drive D: for documents, e.g. photos, Office documents, music, etc.

This makes it easier to image data using data imaging products such as O&O DiskImage.

Image

An image is a “copy” of your drive or partition. This “copy” contains all information taken from the original. A spe-

cial feature of an image is that the file format is specially compressed and takes up much less disk space than the

original. The more often you create images of your drive, the less you need worry about data loss. Should data on

the original drive be lost or damaged, you can restore your last image with all its data onto your computer. With

just a few mouse clicks, you can recover the original status of your drive before the last imaging.

An image can be made up of multiple image files (*omg). For example, when one disk is not large enough and the

image is split onto two disks.

Image file

An image can be made up of one or more image files (*omg). If, for example, the disk where you want to save the

image isn't large enough, you can split the image onto multiple disks. When you split your image onto several disks,

a new image file will be created on each disk and together, these image files will be parts of one entire image. It's

important to number the disks (CD/DVD) in case you want to later restore a drive using the image, or use it as a

base for an incremental imaging.

Complete image

Using the Complete image method, the data selected for imaging will be imaged all over again and stored in a

folder on the target disk. Complete images can be created using the "Used sector", "Forensic", or "Direct foren-

sic" methods.

Differentiation: Image of the changes

If you want to image changes to your hard disk or of your partitions, you must have created at least one complete

image. Changes made can be saved as differential and incremental images.
