Ext3

Officially introduced with their version 7.2 of the Linux operating system,
Ext3 is the Red Hat Linux journaling file system. It is forward and backward
compatible with Linux Ext2. It has multiple journaling modes and broad
cross-platform compatibility in both 32- and 64-bit architectures.

2.3.6 Linux

ReiserFS

The ReiserFS file system was officially added to Linux in 2001. ReiserFS is
free of most of Ext2 disadvantages; and it is a 64-bit journaling file system
with dynamic allocation of memory for data structures.

2.4 Partitions

As previously mentioned, a physically formatted disk has to be partitioned.
Each partition may be viewed as an independent unit that can be formatted
with any desirable file system.

2.4.1

When is it Useful to Have Multiple Partitions?

Formatting the whole hard disk with one file system is not always the best
way to use your disk space and resources. On the contrary, several partitions
allow you to:

•  Install more than one operating system;
•  Use disk space more effectively and efficiently;
•  Physically separate programs and data according to functions or some

other feature.

2.4.2

Partition Structure on a Hard Disk

A special place – a partition table – is left in the very first sector of the hard
disk (this sector is called MBR, or Master Boot Record) to store information
about the hard disk partitioning. This table consists of four entries and
contains the following information about the partition:

•  Status (a flag that shows if a partition is active);
•  Type (0 – the entry is empty);
•  First sector number;
•  Size in sectors.
