Modern computers allows you to install two or more operating systems on single hardware. This configuration is known as Multi-boot (generally called dual-boot). You can use features of different operating systems and can work independently on them. In some situations, where you use dual-boot configuration with Linux operating system, you may face serious issues of system metadata structure corruption that leads to serious data loss. At this point, it become essential to go for Linux Data Recovery to get your mission-critical data back. In a practical scenario, you might come across following error message when you try to install Fedora Core to make your system dual-boot with any other Linux distribution:

“The partition table on device is corrupted. To create new partitions it must be initialized, causing the loss of all data on this drive” In such cases, the partitions still boot properly. But under the System Tools-> Hardware browser, you just see a large green bar for hard drive. It does not show the hard drive volumes. When you run fdisk to perform Data Recovery Linux, you get following result: “Disk /dev/hdc: 100.0 GB, 100030242816 bytes 16 heads, 63 sectors/track, 193821 cylinders Units = cylinders of 1008 * 512 = 516096 bytes Device Boot Start End Blocks Id System Partition 1 does not end on cylinder boundary. Partition 2 does not end on cylinder boundary. Partition table entries are not in disk order”

Root of the problem

As sated in the first error message, this issue generally occurs due to corruption to the partition table. Partition table is the most important data structure of Linux operating system that stores critical information about hard drive partitions. This information is required by the operating system to access hard drive partitions. In case of damage to the partition table, all of your critical data gets deleted and you need Linux Recovery to get your data back. This is possible through Linux Data Recovery software. The applications use advanced scanning algorithms to systematically scan the damaged hard drive and retrieve lost data from it. They have simple and interactive graphical user interface to allow Do It Yourself recovery. With read-only and non-destructive conduct

Stellar Phoenix Linux Data Recovery is the most effective and advanced tool that ensures absolute recovery in all cases. It supports recovery from Ext4, Ext3, Ext2 and ReiserFS file system volumes. The software is works well with all major distributions of Linux operating system.

The native partition type code used by a Linux hard drive is 0×83 irrespective of the file system (ext2, ext3, reiserfs etc.). When you partition your hard drive using fdisk or any other utility, it often consists of two partitions: a root directory partition (denoted as ‘/’) and a swap partition. A partition table is the index table that references all Linux hard drive partitions. So, if this table gets corrupt, the system couldn’t locate and thus access the partitions. In such situations, you need to use your recent data backup and restore lost information from it. However, if data backup is non-existent, invalid or not updated, Linux Data Recovery tools can be used to scan the affected hard drive.

Consider a scenario, you start your Linux system and it displays the following error message:

“The partition table on device <drive_name> was unreadable”

Cause

The partition table is corrupted or damaged. It can get corrupt due to unexpected shutdown, incorrect installation of updates, improper use of terminal commands, erroneous use of disk partitioning utilities, partition resizing and other similar causes.

Solution

To correct this issue, you need to carry out these steps:

You need to ensure that at least one of the partitions has been marked as Active

If you can boot the operating system, you should immediately backup all the important data

Next, you need to delete all the existing partitions and then recreate them. To accomplish the same, you can use fdisk or any other disk partitioning utility

Repartitioning the hard disk erases all the previously stored data. So, you need to use your recent data backup to restore it. If the data backup is not present or up to the mark, you need to scan your hard drive using Linux Recovery tools to extract the lost data.

Linux Data Recovery applications incorporate advanced scanning procedures to recover and restore the lost data. With elf-explanatory interface, these utilities provide easy recovery. In addition, these recovery software are read-only tools and hence they don’t perform any write operation. You can use these tools in any logical data loss case.

Stellar Phoenix Linux Data Recovery is efficient Linux Recovery tool. The software supports advanced recovery features and provides effective recovery results. It is a read-only tool that supports Ext2, Ext3 and ReiserFS file systems. This  Linux Data Recovery tools is compatible with almost all Linux distributions like Gentoo, Turbo Linux, SlackWare, SUSE etc.

Are you unable to mount your Linux hard drive volume? Are you facing superblock, inode, or file system corruption like error messages while booting your Linux system? Such situations are caused by corruption of Linux hard drive metadata structures. This behavior of Linux operating system renders all your significant data inaccessible and leads to significant data loss. In order to get your mission-critical data recovered, you should opt for Linux Data Recovery solutions through reliable tools.

In a practical scenario, you may encounter the below error messages after copying your data through ddrescue command-line tool and running e2fsck utility:

“Superblock has a bad ext3 journal (inode 8).
Clear? Yes”

Or

“/dev/sdf was not cleanly unmounted, check forced.
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Missing ‘..’ in directory inode 1785876.
Fix? Yes

Pass 3: Checking directory connectivity
Root inode is not a directory; aborting.
e2fsck: aborted
fsck.ext2 /dev/sdf failed (status 0×8). Run manually.”

After the above error message, you can not access your precious data from the hard drive. In order to get your lost data back, and to sort out these errors, you should perform Data Recovery Linux.

Resolution

The problem is caused by bad block at the starting of inode table. You can fix the problem by reconstructing root inode. It is quite easy to reconstruct the root inode, however the problem is that root inode needs to be placed at fixed location and currently a bad block is located there.

Forcing the hard drive to use spare block from its pool is possible, however a bad block is often an indicator of the beginning of hard drive crash. Thus, replacing the affected hard drive with new one is the safest way to recover from this situation. Use ‘dd’ command to copy data from old hard drive to new one. Then run e2fsck to create a new root directory on the new hard drive, and shift all the inodes, respectively.

If the above method does not solve your problem, Linux Recovery applications perform absolute recovery. They use high-end scanning techniques to methodically scan the entire hard drive and get all your precious data recovered. The Linux Data Recovery software come equipped with simple and rich graphical user interface to enable easy recovery.

Stellar Phoenix Linux Data Recovery is the most effective solution for all logical data loss scenarios. The software recovers Ext4, Ext3, Ext2, FAT12, FAT16, and FAT32 file system volumes. It is compatible with all major distributions of Linux operating system such as Red Hat, Debian, Fedora, SUSE, and Ubuntu.
