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.
