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.
Partition ID (or File system ID) is a file system identifier that is placed in the partition. It is used to quickly detect
partitions of supported types. A number of operating systems completely rely on it to distinguish supported
partitions.
Partition ID is saved in appropriate entries of the Partition Table and takes only 1 byte of space.
Partition Label (or Volume Label) is a small textual field (up to 11 characters) that is located in the partition's
boot sector. This value is used for notification purposes only. It is detectable by any partitioning tool including
the DOS FDISK utility.
Modern operating systems save it within a file system, e.g. as a special hidden file. Thus it is able to contain a
relatively large amount of text in multiple languages.
Partitioning Scheme 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.
Recovery Media is a CD/DVD disc, a USB flash card or even a floppy disk from which you can boot for
maintenance or recovery purposes.
Root Directory is the top-level directory of a formatted logical drive to include other files and directories. In
modern file systems (Ext2/Ext3, NTFS and even FAT32) it does not differ from other directories. This is not the case
for old FAT12 and FAT16 file systems.
Serial Number. In the DOS partitioning scheme, every hard disk and every partition has a 32-bit serial number
represented by an 8-figure hexadecimal value. It is stored in the MBR and its value is assigned when the MBR
sector is initialized by Microsoft standard disk managing tools, such as Windows Disk Administrator and the FDISK
utility.
In fact, a hard disk's serial number is not important for most operating systems and software. It is known that
Windows NT, 2000 and XP store its value in the database of assigned drive letters.
A partition's serial number is stored in its boot sector (in FAT16, FAT32 and NFTS file systems). Its value is assigned
when the partition is formatted. It does not play an important role for most operating systems and software as
well.
