In a Linux system, the basic partition type code that is used commonly is 0×83. It is used across most of the file systems such as ext2, ext3, ext4, etc. When a hard disk is partitioned in a fresh Linux system, it consists of two partitions, a root directory partition and a swap partition. A partition table is the table that references all the hard drive partitions.

This partition table can get corrupt because of various reasons such as abrupt system shutdown, virus infections, damaged file system, interrupted hard drive repartitioning, resizing or file system conversion, etc. To overcome system corruption, you should replace it with an updated backup. However, if it is not available then you should use the Linux data recovery tools to recover lost data.

Consider a scenario wherein you switch on your Linux system. The system fails to start and the following error message is displayed:

“The partition table on device was unreadable.”

Cause:

The cause for the aforementioned error message is that the partition table is corrupted and, therefore, inaccessible.

Resolution:

To address this issue, you should repartition the hard disk. This can be done by following these steps:

• Ensure that at least one of the partitions has been marked as Active.

• Immediately backup all the important data, provided system is able to boot.

• Delete all the existing partitions and then recreate them. To do this, you can use “fdisk” or any other disk partitioning utility.

The above mentioned steps can recreate partitions in the hard disk but it may erase all the data in it. You need to restore data with updated backup. However, if it is not available then you should use Linux recovery tools to recover lost data. These tools facilitate data recovery for Linux systems by employing complex scanning algorithms to recover and restore lost data. These highly interactive tools are read-only in nature and, therefore, do not perform any write operations on the original data. Also, these tools do not require any prior technical knowledge to recover lost data.

Stellar Phoenix Linux Data Recovery software is a robust tool that enables data recovery in Linux systems that have either of the Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes. This Linux Data Recovery tool is compatible with various Linux distributions such as Red Hat, SUSE, Debian, Caldera, Mandrake, Sorcerer, TurboLinux, Slackware, Gentoo etc.
