You can effectively manage your valuable data on Linux hard disk by dividing it into various logical disks, known as volumes. Every hard drive volume works as a different hard drive and can be used to store various kinds of data. Every volume has a file system, which can be Ext4, Ext3, Ext2, or any other Linux-supported file system. The volumes are managed in partition table, which is stored the first sector of hard drive. In case the structure or file system of a Linux volume gets damaged, it becomes totally inaccessible and you come across sever data loss. In order to get your mission-critical data recovered in such situations, Linux recovery becomes need of hour.

Linux os requires at least one hard disk volume for the root file system. The swap partitions and / or swap files can be used by it, but latter are more effective. Thus, generally the user wants a dedicated swap partition. Basic Input / Output System can generally access only first 1024 hard disk cylinders on Intel hardware. Due to the same, various users with large hard drives generally create third volume, which has small size of few MB.

This partition is generally mounted on the boot directory for storing kernel image and some auxiliary system files that are required at start up. The data of this volume is directory accessing to BIOS. There can be several reasons, like security, easy of backup and administration or testing to create more than one hard disk volumes.

You can create several hard disk partitions using fdisk command line utility in Linux os. It is a menu drive application or program, which is helpful to create and manipulate hard drive partition tables. This utility understands only the DOS type hard disk partition tables.

However, fdisk program can not understand GUID Partition Table and it is not designed for the large volumes. In such cases, GNU parted helps you to repartition the hard disk.

Before you use the fdisk or GNU parted utility, you must backup all the data else you may face severe data loss if the process gets interrupted. In such cases, you need to perform data recovery Linux by fixing it issue.

Linux data recovery is best possible using powerful and advanced third party applications, known as Linux data recovery software. They are totally safe and easy to use with read-only conduct and rich GUI.
