<P>is the 0th sector of the disk. MBR (Master Boot Record) contains important information about the disk layout: - The used partitioning scheme; - The starting records of the Partition Table; - The standard bootstrap code (or the initial code of boot managers, disk overlay software or boot viruses). Generally, the 0th sector is used for similar purposes in all existing partitioning schemes. The MBR capacity is not sufficient to contain sophisticated boot programs. That's why the on-boot software is allowed to use the entire 0th track of the disk. For example, boot managing utilities such as LILO, GRUB and Paragon Boot Manager are located in the 0th track.</P>
<P>is a set of rules, constraints and format of the on-disk structures to keep information on partitions located on a hard disk. There are known several partitioning schemes. The most popular of them is the so-called DOS partitioning scheme. It was introduced by IBM and Microsoft to use multiple partitions in the disk subsystems on IBM PC compatible computers. Another popular partitioning scheme is the so-called Logical Disks Model (LDM) that originates from the UNIX mainframe systems. Veritas Executive accommodates a simplified version of LDM to the Windows 2000 operating system. Windows 2000 and XP support two quite different partitioning schemes: the old DOS partitioning scheme and the new Dynamic Disk Management (DDM). The problem is that earlier versions of Windows do not support DDM. In addition, most hard disk utilities do not support it as well.</P>
<P>The term backup originates from the time when the best way to protect valuable information was to store it in form of archives on external media. It's become now a general notion to mean making duplications of data for protection purposes.</P>
