5. The image is automatically named after the date of creation. You can, however, enter a name manually. All
information from the image will be saved and can later be accessed through Image Information.
6. Select Start. The image file will now be created.
Note: If one disk is not large enough to save an entire image, you will be prompted to enter a new target path.
Note: If all the connected drives are not displayed, click Imaging in the Ribbon bar and then on Refresh drives.
DiskView
The interactive graphical display gives you an overview of all the hard disks. Free and used space, as well as the size
of the partitions are displayed.
You can select a drive for imaging by double-clicking it.
Among other things, the DiskView of O&O DiskImage will show all empty sectors. These empty areas occur due to
the alignment of the partitions or volumes. Programs such as O&OPartitionManager or the Windows Disk Man-
ager don't show these sectors if they're smaller than the smallest sector that can be partitioned, meaning smaller
than 8 MB on the average.
Since O&O DiskImage creates images of hard disks, it is important to also consider these small areas, if the entire
hard disk is selected as source. These areas can also be made visible indirectly with the Microsoft program "Disk-
Part". If the hard disks were chosen based on the command "SELECT", then it is possible to list these areas with
"LIST PARTITION". Not only the size, but also the Offset, where the partition is located on the hard disk is dis-
played. It may be necessary to consider possible rounding differences, since the display is rounded to the thou-
sands.

Clone drives
Note: Make sure the Advanced start page is being displayed if you want to run this feature. This can be done by
clicking Advanced start page on the O&ODiskImage start page.
By cloning, it's possible to create 1:1 copies of entire disks or individual drives which can then be used instead of the
originals. This function allows you to clone a drive and all its saved data without creating image files. The source
disks/drives will be reproduced without any changes.
Please keep in mind that a clone requires much more free space than an image.
Unlike images, there are no incremental or differential clones possible for reducing the data volume of successive
clones. In addition, a clone cannot be compressed and/or encrypted: something that renders the data useless for
third persons or other unauthorized access.
