The program for creating a virtual disk. Emulation of CD and HDD
Operating systems, starting with Windows 7,are provided with a program for creating a virtual hard disk. When using it, there are no difficulties, because the OS defines such a device as a normal "hard drive". Creating a virtual hard disk can be useful to conveniently demarcate HDD space, organize file storage and even install the operating system.
The virtual partition is created as a VHD file,after mounting (this operation can be performed without installing additional software), the system works with the image in the same way as with a conventional hard disk. The closest parallel can be done with virtual drives of ISO-disks, however, unlike them, new images can be written to the image and the old one deleted. Also, a virtual HDD allows you to encrypt your content, this is useful if there are no unauthorized access to the information. After installing the operating system on a virtual partition, it can be easily and quickly transferred to another computer.
Built-in program for creating a virtual disk
Differences in the creation of a virtual HDD between the seventhand the eighth version of Windows does not. The only innovation that is made in Windows 8 - mounting can be done by double clicking on the file. It does not need to perform additional settings and assign a drive letter manually.
To create a virtual disk, you need to run a special utility "Disk Management". Just click on the icon, going to the panel through the "Start" menu.
Creating a VHD
In the utility that opens, click on the top menu"Action", in the opened list select "Create virtual disk". In the same list, you can see the message "Attach a virtual disk", it will be useful if you already have a VHD file and want to read its contents.
After clicking on the item, suggesting the creation,a master will be opened, so familiar to Microsoft products. Here you will need to choose where to save the VHD file and how much it should be limited. Also here you need to decide whether to dynamically create a partition or leave a fixed size. After clicking on the "OK" button, a new disk will appear in the manager. At the same time, the program for creating a virtual disk can start installing additional drivers.
The next step is to click the rightclick on the disk that was just created, and click on the "Initialize" icon. After clicking the program to create a virtual disk will offer to choose which partition table will be used on the partition - GPT or MBR. If the volume is larger than two terabytes, choose the first option, if less - the second.
The last stage of preparing a virtual HDD -create partitions and connect them to the operating system. As before, right-click on the disk and click on "Create volume". If you specify the size that the system recommends, the program for creating a virtual disk will create a partition that occupies the entire HDD space. If necessary, you can make several sections. Immediately in the window you can set a letter for each.
After all the operations in the Explorer window are completedthe icon for the new hard disk will be displayed. All operations with it can be performed exactly as if it were a physical HDD. But remember that in fact the VHD file is stored on a real volume, which means that all the data is stored on it.
Each user has differentCDs (with games, programs, video files). Any laser disk is suitable for creating its image or, in other words, a virtual disk. The image file will contain all the data on the CD-ROM. The same information will be stored on the HDD. Thus, you can solve several problems - improve the durability of a physical CD, use a disc, even if the drive fails, completely reduce the noise of a real disk drive when reading data. In addition, access to information will be at a higher speed.
