Interrupted Fsck Operation Causes Data Loss In Linux

In Linux operating system, fsck is a useful utility that helps you to check file system integrity and fix the errors

. It is helpful particularly in case of file system corruption, dirty system shutdown and operating system related issues. When improper system shutdown happens, fsck runs when you reboot the system and check file system integrity. But if fsck process gets terminated due to improper system shutdown or power failure, you might come across serious data loss issues. In such circumstances, you are required to opt for effective and powerful Linux Data Recovery solutions.

In a practical scenario where fsck process gets interrupted due to power outage, when you restart the system, all of your hard drive volumes are found to be inaccessible. It cause critical data loss situations. When you try to sort out the problem by using fdisk command on Linux hard drive, you see following message:

Cause

As stated in the above error message, the problem is caused by corruption to partition table. It is an important data structure of Linux operating system that stores important information about hard drive partitions/volumes. It is a 64-byte table, which store four partition entries, 16 byte for each.

Damage to the partition table means your operating system could not locate partitions on hard drive and thus can not access them. In other means, you need to carry out Data Recovery Linux for fixing this issue.

Resolution

In order to work around this issue, you need to format the hard drive and reinstall Linux operating system. It will replace the damaged partition table with new one, after that system will work perfectly. But formatting the drive would remove all the data from it and you face serious data loss situations.

Linux Recovery in such situations is possible using commercial Linux Data Recovery software. The applications are completely safe and easy to use and perform absolute recovery in most of the data loss situations.

Stellar Phoenix Linux Data Recovery is the most comprehensive solution for all types of data loss situations. It recovers lost data from Ext4, Ext3, Ext2 and ReiserFS file system volumes. The application is usable with all major distributions of Linux operating system.
