Superblock is the most significant component of a Linux volume that restrains critical information about files and folders in file systems as ext2, ext3 and more. It enables us to mount and access the file systems. Superblock corruption primarily occurs due to metadata structure damage, file system corruption, unexpected system shutdown, malicious software like virus and more.

In most cases of superblock corruption, the volume becomes unmountable and the data becomes inaccessible. In such situations, you can restore the lost data using an updated backup. However, if you have not maintained any backup or it is not up-to-date, then you need to recover your data by using advanced Linux Data Recovery tools.

Consider a practical scenario, when you attempt to boot your Linux system, you encounter the below error message:

“Wrong fs type, bad option, bad superblock on /dev/hda8, missing codepage or helper program, or other error. In some cases useful info is found in syslog – try dmesg | tail or so”

After running dmesg tail, you encounter the below error message:

“Couldn’t mount because of unsupported optional features (2000200)”

After the above error message appears, the system becomes unmountable and data stored on the hard drive volume becomes inaccessible. Additionally, you encounter the same error message each time you attempt to boot your system.

Cause:

The main reason behind occurrence of the above error message is superblock corruption.

Resolution:

To resolve the problem and access all inaccessible data, you need to follow these steps:

1. Boot your system by using an alternate block by running the below command:

e2fsck -b 98304 /dev/hdb8

2. Once the file system gets restored to the point at which it can be mounted, you need to fix it by using this command:

e2fsck -c /dev/hda8

-c parameter checks for the bad blocks

However, if the above steps are not able to resolve the issue, you should consider reinstalling Linux. A clean Linux reinstall will erase all existing data from the selected volume. For complete recovery of lost data, you should use efficient Linux Data Recovery software.

Such Linux Recovery tools incorporate effective scanning algorithms to recover all your lost data. These recovery tools provide highly graphical user interface that makes them easily understandable without prior technical knowledge. These tools recover data post situations like superblock corruption, group descriptor faults, inode table damage and more.

Stellar Phoenix Linux Data Recovery is the foremost Linux Recovery tool. It supports recovery from Ext2, Ext3 and ReiserFS file system based Linux volumes. This Data Recovery Linux tool gets installed on Windows (Vista, XP, 2003 and 2000) and the affected Linux drive is connected as slave.

Could the mass media hype about computer viruses actually make the problem worse?

If you believe what you hear in the media, there are an awful lot of viruses going around. No, I’m not talking about the make-you-sick kind of virus, though they get plenty of airtime, too. I’m talking about the kind of virus that enters via your internet connection rather than your nasal passages.

What the mainstream media often don’t tell you–at least, in most radio and television newscasts and in the crucial headlines and opening paragraphs of newspaper articles– is that many of these “viruses” are not viruses at all.

What Computer Viruses Really Are

The main reason the mainstream media always are in alarm over viruses is that they tend to call any malicious computer program a virus. In reality, there are at least eleven distinct types of malicious software, or malware, commonly affecting computers today. The most common of these are worms, Trojans, and spyware.

So, what’s the difference between computer viruses and the other types of malware? The difference is that computer viruses are just about the only ones that regularly shut down computers and cause other obvious damage. The most common of the other kinds of malware–worms, Trojans, and spyware–are usually only detectable with a special scan.

The Real Danger of computer Viruses

If the other types of malware are so unobtrusive that they can only be detected with a special scan, then what’s to worry about? For starters, these programs are called malicious for a reason: they are designed to cause some kind of damage, if not to your computer, then to someone else’s.

Worms are most famously used to damage, destroy, or disrupt other computer networks than the one on which the host computer is located. For instance, worms have been used by website owners to shut down rival websites by sending overwhelming numbers of requests to the computer that hosts that website. Worms have also been used to send out viruses to other computers, often without infecting the host machine–after all, what would it benefit the worm to shut down its host computer?

Trojans, in turn, are often used to insert worms and other malware on your computer, even if the Trojan itself does no damage.

But even if you don’t care what happens to anyone else, you should still be concerned about one kind of malware: spyware, a kind of malware that, true to its name, collects data from your computer and sends it back to a remote host.

Most spyware is only interested in monitoring your internet usage so it can tell other programs, called adware, what advertising to popup on your computer. However, there are criminal spyware programs that steal financial data, or perform a thorough identity theft. Don’t think you have personal or financial data on your computer? Some spyware programs contain a key logger, which is a program that copies whatever you type, usually in order to snatch passwords. Even if you keep no financial information on your computer, if you ever buy anything over the web, the key logger would allow its owner to buy stuff using the same information you typed in to buy stuff yourself.

Why Blame the Media?

Given the danger of all these different types of malware, isn’t it a good thing that the mass media are becoming hysterical about it? And can’t they be forgiven the sloppy reporting of calling Trojans, worms, spyware, and other malware “viruses”?

No, no, no.

This is a classic case of bad reporting doing more damage than no reporting at all. In this case, the damage bad reporting has done is to promote a common myth that goes something like this: “The only malicious software is a virus. Viruses damage your computer. Therefore, if my computer is working OK, my computer has no malicious software. I only need to scan my computer for problems when there is a sign of problems.”

Thanks to this myth, many people complacently let their antivirus software go months out of date, not wanting to be bothered with scheduling an automatic update. Just as bad, many people don’t have any extra software to combat the other types of malware that may not be covered by antivirus software.

In fact, it’s not uncommon for people who have found malware on their computers after a scan to say, “But I never had malware on my computer before!” But how would they have known if they had never scanned!

Until the biggest mainstream media–and especially television–start educating the public about the need to have their computers automatically scanned at least daily, the world will continue to have major, drawn-out problems with malware that could have been wiped out as soon as soon as the anti-malware software makers discovered it.

And until that day, the mainstream media will have many more opportunities to run hysterical stories about “viruses,” thereby forcing them to sell more newspapers and broadcast to even larger audiences of people who suck at the information trough yet somehow never become full.

The EXT3 file system in Linux is divided into various block groups. Each block group further contains a data structure called “group descriptors” that contains critical information about the block. Corruption in group descriptors primarily occurs due to operating system malfunctioning, file system damage, malicious software like virus and more. Two major outcomes of corrupted group descriptors are unbootable system and inaccessible data. To successfully recover the lost data, restore it from the latest backup. In case, no recent backup is available or is invalid, you need to go for advanced  Linux Recovery software.

Consider a practical scenario, where you encounter the below error message when you attempt to boot your system:

“Uncompressing Linux:…Ok booting kernel

audit(xxx.x….x..:0) : initialized

EXT3-fs error (device hda3):ext3_check_descriptors:Block bitmap for grade 38 not int grade ( block 34799616)

EXt3-fs:roup descriptors corrupted.

Mount: error 22 mounting ext3

pivot root ivot_root (/sysroot, /sysroot/initrd) failed: 2

unmount/initrd/proc_failed:2

kernel panic: No init found: Try passing init=0 to kernel”

You encounter the same error message each time you attempt to boot your system. As a result of the above error, all your critical data becomes inaccessible.

Cause:

The above error message is encountered when group descriptors are corrupted.

Resolution:

To resolve the above issue and access the data, you need to use FSCK command. This command is mainly used to repair the EXT3 file system. But, if the file system has been badly corrupted, then this command fails to repair. In such circumstances, you need to recreate the file system again by formatting and reinstalling Linux. A clean reinstall of Linux will completely erase all data from the selected Linux volume. For complete and orderly recovery of data after reinstalling Linux, you will need to se powerful Linux Recovery software.

These Linux Data Recovery applications ensure comprehensive scanning of formatted Linux volumes by using powerful scanning algorithms. These recovery tools can recover and restore data after problems like group descriptors faults, Inode table damage and superblock corruption. They are built with highly graphical and interactive user interface that makes them easily understandable without prior technical skills.
