NTFS Boot Sector The table Boot Sector Sections on an NTFS Volume describes the boot sector of a volume that is formatted with NTFS. When you format an NTFS volume, the format program allocates the first 16 sectors for the boot sector and the bootstrap code.
Partition Tables on MBR and GUID disks Master boot record (MBR) disks use both basic volumes and dynamic volumes. Because partition tables on MBR disks support partition sizes only up to 2 terabytes, you must use dynamic volumes to create NTFS volumes over 2 terabytes.
The following information describes how clusters and sectors are organized on an NTFS volume , how the boot sector on the volume determines the file system, and how the Master File Table (MFT) organizes structures on the volume. Clusters and Sectors on an NTFS Volume A cluster (or allocation unit ) is the smallest amount of disk space that can be allocated to hold a file. All file systems used by Windows Server 2003 organize hard disks based on cluster size, which is determined by the number of sectors (units of storage on a hard disk) that the cluster contains.
A file system is a required part of the operating system that determines how files are named, stored, and organized on a volume. A file system manages files and folders, and the information needed to locate and access these items by local and remote users
According to Murphy’s Law of Data Loss , "The probabilities of a hard disk crash increase with the number of days since the drive was last backed up." No hard disk drive is ever completely safe from crashing, and losing all the important data on it. A disk drive can be damaged due to a number of causes such as virus attack , voltage glitches , software malfunction , hard disk format , accidental file/directory deletion , human error or even sabotage . Such events cause corruption or damage to the disk drive, and make the data completely inaccessible to the user.
Natural Disasters is the least likely cause of data loss however they can kill an entire company. The eruption of natural disasters and the complete equipment failure are rare but they do occur. Although it accounts for around 3% of all data loss but the magnitude of data loss is highest
