What is a disk image?
A disk image is a file which is an exact and complete image of a floppy disk. The image contains information on the disk format and structure, such as FAT, boot sector, directories, and all files. By using WinImage, you can create an exact copy of an original disk, including non-standard capacity and format disks. As an example, you can read a floppy disk and copy it as one image file to your hard disk. Later, without using the original floppy disk, you can extract any file from the image – just as if you had copied the file from the original floppy disk itself. You can create exact copies of the original disk onto new floppy disks. You can also create disk images with WinImage. For example, if you want to put five files, taking 1.3 Mb, on a 3″1/2 HD that has a normal capacity of 1.2Mb, you can create an empty 1.44 Mb image on the floppy, inject the five files into it from the hard disk, and in one operation you have formatted the floppy and written the image on it. Unlike the DOS Disk
A disk image is an exact representation of a hard disk or partitions of a hard disk. The image generally contains compressed data and only contains parts of the disk that are currently in use by the file system. For a more detailed description, please read the following.. Sectors Every computer hard disk is divided into addressable blocks called sectors. }}–> }}–> Each sector is }}–> }}–>512 bytes of data and each hard disk defines its partitions (drive letters in Windows) as a start sector, relative to the beginning of the hard disk, and length, the total number of sectors between the first and last sector in the partition. File System Each partition will usually be formatted into a file system; for Windows XP, this means either = 4 && typeof(BSPSPopupOnMouseOver) == ‘function’) BSPSPopupOnMouseOver(event);” class=”BSSCPopup” onclick=”BSSCPopup(‘NTFS.asp?nohead=y’);return false;”>NTFS or = 4 && typeof(BSPSPopupOnMouseOver) == ‘function’) BSPSPopupOnMouseOver(event);” class=”BSSCPo
Why is it needed? Answer Disk Image is a mirror of your logical drive that is stored in one file. A Disk Image file can be useful when you want to back up the contents of the whole drive, and restore it or work with it later. Before you start recovering deleted files, it may be a good idea to create a Disk Image for this drive, if you have enough space on another drive. If something goes wrong while recovering the files (for example, recovering them onto the same drive could destroy their contents), you will be able to recover these deleted files and folders from the Disk Image that you have wisely created.
