What Is a Partition Table?

Partition table is to divide the data of a large table into many small subsets called partitions. The types are FAT16, FAT32, NTFS, exFAT, Ext2 / 3/4, HFS +, VMFS. In addition, the types of partitioned tables are mainly divided into range (range), list (list), and hash (hash) partitions. The division is based on the internal attributes of the table. At the same time, a partitioned table can create its unique partitioned index. If the hard disk loses the partition table, the data cannot be read and written in sequence, resulting in inoperability.

Many small partitions

FAT32 Partition table FAT32

A file system derived from the File Allocation Table (FAT) file system. Compared with FAT, FAT32 can support smaller clusters and larger capacity, which can more efficiently allocate disk space on FAT32 volumes.

NTFS Partition table NTFS

An advanced file system capable of providing performance, security, reliability, and advanced features not available in various FAT versions. NTFS can use log file and checkpoint information to restore file system consistency. In Windows 2000 and Windows XP, NTFS also provides advanced features such as file and folder permissions, encryption, disk quotas, and compression.

the difference

(1) Win 2000 can support both FAT32 and NTFS file systems. FAT32 is longer than compatibility with Win 9X, and NTFS is longer than system security.

(2) FAT32 file system can relocate the root directory and use FAT backup copies. In addition, the boot record of the FAT32 partition is contained in a structure containing critical data, reducing the possibility of a computer system crash. The compressed file on the NTFS partition does not need to be decompressed by other programs before reading and writing. When the file is read, the file will be automatically decompressed; when the file is closed or saved, the file will be automatically compressed.

exFAT Partition table exFAT

exFAT (Extended File Allocation Table File System, also known as FAT64, that is, the extended file allocation table) is a Microsoft introduced in Windows Embeded 5.0 or higher (including Windows CE 5.0, 6.0, Windows Mobile 5, 6, 6.1) The file system suitable for flash memory is introduced in order to solve FAT32 and other files that do not support 4G and larger files. For flash, NTFS file system is not suitable for use, exFAT is more suitable.

Ext3 Partition table Ext3

EXT3 is the third generation extended file system (English: Third extended filesystem, abbreviated as ext3), is a journaling file system, and is often used in Linux operating systems. It is the default file system for many Linux distributions. Stephen Tweedie's kernel mailing list in February 1999 first showed that he used the extended ext2, which was incorporated into the kernel mainline starting with the 2.4.15 kernel.
