Free Hard Disk Imaging Software

Hard disk image (or partition image) is a file that contains all the data that is needed to recreate a particular disk or partition. Hard drive may be split into many partitions. Each partition has own file system andunder operating system it is visible as one disk. Disk or partition image is usually created for backup purposes or to copy/clone the whole disk. Disk image (or partition image) is a convenient way to create a complete backup of the disk—it allows the fastest restoration off all the files including operating system.

Disk imaging software is used to create, write and manage image files which are usually compressed to save disk space. We can create a complete image where all the clusters and sectors are written to the image or we can save only used data. Each file system has tables that define which disk sectors are used by folders and files. By taking into account this data the disk image will be smaller but will still contain all the data to faithfully recreate the disk partition. Some disk tools also have a function to create a virtual disk from an image file. The disk will be mounted as read only, but you will be able to easily extract individual files.

Creating disk images is a quick and efficient method of creating a complete backup of any disk. With disk image you can restore any partition regardless of the hard drive size. One example of practical usage of disk images is when you install operating system on a new computer. When everything is installed and configured properly you create an image of the disk. Now you can use the computer and whenever there is a problem with file system corruption or hard drive failure you replace the drive if necessary and restore the disk image. With a simple operation you will have the operating system with applications installed in minutes. This approach can also be used when the disk becomes cluttered with many applications that you don’t need anymore or can not be easily uninstalled.

One disadvantage of creating disk images is that this operation is time consuming and needs a lot of space to store the images. So you will create images only few times a year. In the meantime you should make ordinary backups of individual folders and files. One potential problem when creating disk/partition image is when we need to make an image of the system disk. In such case if this is a Windows system the imaging software can use the Microsoft Volume Shadow Service to bypass problems with locked files used by the operating system.
