How To Create Disk Images

Part 1.

If with music, movies and books more or less clear even for a beginner - the toys and their installation is sometimes baffled even experienced users.

It's about the so-called disc image formation, that is most precise way to copy a CD / DVD information, invisible to the user until the boot sectors and other concealed information, and packaged as a single file size of this very DVD. Create this Disk-Image in special programs, one of the most famous and ordinary - UltraISO.


 Disk images can not only speed up the game, to reduce noise while watching video, the drive to avoid wear and damage of the optical carrier with frequent use, but also to run games on computers not equipped with an optical drive such as a compact notebook. Many users immediately after the purchase of the disc makes his image up and then it was already enjoy this virtual backup copy without fear of physical damage to the disk or its loss due to illegal acts of animals or young children.

A pair of MDF / MDS - is also a disc image, but in the form of two files - so clever program copies the disks of Alcohol 120%, even coping with advanced types of copy protection. In addition, there are images with the expansion of NRG (the image was shot using Nero Burning Rom), IMG, CCD, a pair of BIN / CUE, and so on. All this-disk images taken with different programs and with only some differences in their internal structure. Why come up with such complexity, why not just copy the files from the DVD via the normal Windows Explorer? Just below and we'll deal with it. In the meantime, back to our file with the game. So you have downloaded this same ISO file and now want to install this game on your computer. The first action, which usually does in such a case, a novice user - click on the downloaded file with the mouse. And then there are two versions of events. First - your system does not yet know what the ISO, and she asks you what to do with this file, what program to open it? The user does not know, he falls into a stupor, or at best trying to find out via the Internet or friends. The second option, you already have some kind of program that knows about the ISO-files, such as archiving. Yes, many modern archivers (for example, our favorite PowerArchiver) perceive ISO-images as ordinary files.

In this case, the unexperienced user with archiver simply unpacks the contents of the ISO into a folder on the disk as if it were a normal bt ZIP or RAR-archive. As a result, he gets exactly the same thing as if he had simply copied the entire contents of the DVD-ROM drive with the game on a disc through Windows Explorer. Next, the user finds a file named like SETUP.EHE or INSTALL.EXE, understands that this is exactly what you need to run to install the game starts, the game even starts to be put, and even installed! Hooray! On the desktop, a new label - a mouse click on it to enjoy the latest hit of the game industry, and here - OH! We see the message: Insert the DVD-ROM game. "Where did we hire him, if we have downloaded the game from the tracker? We do not drive, and ISO file - where and, most importantly, who can insert a file? That's why we (and other) and were invented by formation of disks and the so-called virtual DVD-drives. So, the correct way to solve the problem with disk images will be as follows. First, you must download and install the Daemon Tools Lite (daemon-tools.cc / en / products / dtLite). For the vast majority of users will be the best option, since Daemon Tools Lite is free, simple and easy to work, does not contain unnecessary functionality. If you want more in the future and create images that will make sense to look for paid version of Daemon Tools or the already mentioned program Alcohol 120% (alcohol-soft.com) - with the help of their own is quite convenient to transfer the images back to the DVD RW-discs.
