Creating and Manipulating the Linux Volumes Can Cause Data Loss

You can effectively manage your valuable data on Linux hard drive 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 severe data loss. In order to get your mission-critical data recovered in such situations, Linux data recovery becomes need of hour.

Linux operating system requires at least one hard drive 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. BIOS (Basic Input/Output System) can generally access only first 1024 hard drive 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 startup. 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 drive volumes.

You can create several hard drive partitions using fdisk command line utility in Linux operating system. 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 drive partition tables.

However, fdisk program can not understand GPT (GUID Partition Table) and it isn't designed for the large volumes. In such cases, GNU parted helps you to repartition the hard drive.

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 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 graphical user interface.
