Data Recovery after Root Directory Corruption in Linux

To manage the files stored on any partition or volume, Hierarchical Directory Structures is used. This logical tree of directories is used in every file system, as the intuitive way to manage the files. Much like the real tree has all the roots and branches come together in one spot, so too does a file system directory structure. The base directory of the logical tree is known as “Root Directory”.

Root Directory is a directory that includes all other directories. In Linux as well as other OS, the root directory has no specified name. It controls the activity of the all other directories in the tree. It works as the Catalog file in Windows and Mac operating system. It contains the address and path of all the files stored on your computer hard drive. Operating system reads the files from this logical tree and display it to user. Sometimes while trying to access a Linux file, you may get the following error messages:

• Can’t access the file
• No such file or directory
• File not found

These error messages can occur when the root directory of your file system is corrupted and your operating system can’t find the path of specified file and fail to access it. This event of root directory corruption can lead to data loss.

In these situations of data loss, you need for data recovery solutions to recover your lost data. In this case, you can recover your lost data with the help of Linux recovery software.
Linux data recovery software are specially designed data recovery software to recover the lost or inaccessible data from the Linux based hard drive. These software uses advanced scanning algorithms to search and locate the lost data and then recover them. These data recovery software can also recover the Linux volumes with corrupted Inode or super block.

Stellar Phoenix Linux Data Recovery software is the advance yet powerful data recovery software. This the best data recovery program to recover and restore Linux files after a virus attack, hardware crash and formatted drives. The software is capable to recover the lost data from Ext2 and Ext3 file systems of Linux. This data recovery software gives expertise results to recover your precious data. It is a fully automatic data recovery software that can recover data from all models of hard drives including IDE, EIDE, ATA, PATA, SATA and SCSI.

How to Recover Data Lost while Resizing Ext2 Partition in Linux

Different Operating Systems use different file systems to manage their files stored on hard drive. File System is a method for storing and organizing computer files and the data they contain to make it easy to find and access them. Like FAT and NTFS file systems in Windows, Ext2 or Extended File System is a file system used in Linux Kernel. It is faster file system and it is used as the benchmarking standard.

We use file systems on the logical partitions of hard drive. Hard drives are partitioned to store one kind of data on one partition to manage them effectively. Different partitions can have different size. Sometimes we need to resize the partitions. It is generally required in two cases:

  1. When the particular partition is small and the amount of data is big.
  2. When the partition is big and it decrease the accessing speed.

If any of these conditions take place, we resize the partition by increasing or decreasing the size of other partitions. We can resize the partition using two methods:

  1. Formatting and deleting the partitions and them repartitioning the drive.
  2. Resizing dynamically using software

In case of formatting the drive, data loss may occur. To save the data, we need to resize the partitions using software. These software resize the logical partitions without formatting the drive or affecting the existing data. With the help of these software, you can resize the partitions very easily.

Along with the advanced feature of these software have some drawbacks. They can cause data loss in some instances. For example if your want to increase the size of Logical Drive “D” by taking 5GB space from Logical Drive “E”. In case if you don’t have 5GB of free space on E drive the software will delete the existing data on the drive and take the space for D. in this way, the software may cause data loss.

In these circumstances, the data from drive E become inaccessible and you need for data recovery to recover the lost data. You can perform this task using Linux recovery software.

Linux data recovery software are the application programs designed to recover data from Linux Operating System. In this particular case, you need to purchase a data recovery software that can recover data from Ext2 File System. Before purchasing any Data Recovery software, you should make sure that the particular Linux data recovery software you are going to purchase will support the recovery from Ext2 file system or not.

Stellar Phoenix Linux Data Recovery Software is the most powerful and easy to use Linux data recovery software among all software available in the market. This software uses advanced searching algorithms to search and locate the lost data and recover them. In case if you don’t get the desired result from the general searching options: Standard and advanced of the software, you can perform raw file recovery. This is very powerful tool of this software that searches files according to the file signature. It supports all major file types used in Linux Operating System.
