Resolving “the File System Structure On The Disk Is Corrupt And Unusable” In Windows

Every file on the NTFS (New Technology File System) volume is presented in a particular file, known as MFT (Master File Table). This is the most significant system file, which defines the NTFS file system volume. In fact it is a relational database that contains different several about different files and directories. It works as central management feature and ‘starting point’ of NTFS partition. For proper accessing of a NTFS partition, it is required that the MFT must work properly. Sometimes, it gets damaged and you come across partitions loss situations. In order to retrieve lost partitions in such cases, Windows Partition Recovery is required.

In a practical scenario, when you boot your system Microsoft Windows XP SP2 (Service Pack 2) based computer, the Chkdsk utility automatically starts scanning the hard drive. Furthermore, the below error message is logged into the System Event log of your Windows computer:

“Event Type: Error
Event Source: Ntfs
Event Category: Disk
Event ID: 55
Date: date
Time: time
User: N/A
Computer: computer name
Description: The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume disk letter.”

After successful completion of the scanning process through Chkdsk tool, you can not access files and directories from Windows hard drive. All NTFS disk partitions experience this issue and serious partition loss situations arise. To retrieve lost partitions, you need to identify the cause of this problem and perform Partition Recovery by fixing it.


The problem generally occurs due to damaged or corrupted Master File Table of Windows hard drive. The corruption may occur due to virus infection, operating system malfunction, power surges, improper system shutdown, and user errors.

After corruption to the MFT, operating system can not find file system entries of the files and directories. Thus Windows can not access data from the hard drive and you encounter this issue.


You can prevent this problem by using a hotfix available on Microsoft’s website. If the data loss has already occurred, go for Partition Recovery Software. These are advanced and powerful third-party applications, which work in the majority of data loss situations. They have self-descriptive and rich graphical user interface and thus allow you to perform Do It Yourself Windows Partition Recovery. With read-only and non-destructive conduct, the applications are safe to use.

Hard Drive Failure: Signs And Recovery

Hard drive is the most useful, though unreliable, component of computer system and most of the computer users always try to hide from the fact that hard drive failure can happen anytime. This is for the reason that they take them for granted and don’t expect their failure. On the other hand, some of us do believe that if even a program is hanging up, restarting the system is the sure cure of all such problems, while one can be hard drive failure and instead needs hard drive recovery.

Though this is a fact that a hard drive can survive for years, yet hard drive failure remains the unwanted reality, for the top reasons being moving parts and regular increasing speed of hard drives. So, these hard drives can wear out and the only question is when.

The reason why hard disk recovery is studied as a different concept is the criticality and primary use of hard drive and its data. For the same reasons, hard drive failure is considered worst for the users.

Symptoms of hard drive failure

The pre-warnings of hard drive failure are not always given by failing hard drive, when sometimes the corresponding error messages may appear and sometimes not. The most usual signs are clicking or scratching sounds, while others, lower in ratings, include degrading system performance and unexpected behavior.


If your hard drive is emanating unusual sounds, you need to immediately plug off the system in order to preserve the hard drive recovery probability. Also, this is not recommended to attempt repairs by own as opening the failed hard drive in the common surroundings invite dust particles which are never taken as good by internals and create obstacles in hard disk recovery. The dust particles can disrupt the balance of hard drive as its internals are made with precision and so their tolerance level decreases to an extent so as not to stand such particles. Only Clean Rooms prove suitable to get the hard drive opened.

Hard drive recovery

The verities that the data is important for any organization and hard drives tend to fail led to think about inventing hard disk recovery tool and resulted into what we call as hard drive recovery software . Also known as data recovery service, this is a help offered by experts of the industry. The hard drive recovery technicians know the correct ways to deal with failed internals and recover data with safety. The services are provided through Clean Rooms, where experts apply the suitable set of tools and hard disk recovery procedures.

Stellar Information Systems Limited stands as the leader of hard drive recovery , offering data recovery service through Class 100 Clean Rooms. Stellar’s hard disk recovery experts are known for their worth data extracting abilities and mastership to know the best about hard drive failure cases, data sensitiveness and recovery procedures.

“invalid Record Count” Error Due To Disk Utility Failure

Disk utility in Mac OS X is used to verify disk integrity, repairing file system, checking S.M.A.R.T status and many other tasks . Although the utility can resolve most startup issues, it can also fail under few situations. In most of these situations, a Mac user encounters a disk utility failure error message. To resolve this issue the user needs to perform fresh installation of Mac OS X and use the backup for restoration.

If, unfortunately, the backup is not available then the user can recover its formatted data by using an effective mac data recovery software.

To explain the above scenario in detail, consider an example where your Mac 10.5 system becomes unmountable and you use Disk Utility to resolve the startup issue. But, the utility fails to resolve your issue and displays the below error message:

“Verifying volume “PM G5 hd”
Checking Journaled HFS Plus volume
Invalid record count.
Checking Extents Overflow file.
Checking Catalog file.
Invalid record count
Invalid record count
Invalid record count
Volume check failed.
Error: File system verify or repair failed.”

After the above error message appears, the hard drive becomes unmountable, further resulting in inaccessibility of all the hard drive data.


The root cause for Disk Utility failure error message is severe corruption in HFS ( Hierarchical File System).

How to solve:

To resolve the error message and access the data saved in your Mac hard drive, you will need to take below actions:

Run FSCK command to repair the corrupted file system.
In case the above command fails to master the above problem, then you will need to reinstall Mac OS X.
To access data post re-installation of Mac OS X, in case of no backup availability, you will need to opt for an effective third-party Mac File Recovery utility.

Such Mac Data Recovery tools incorporate intensive, yet secure algorithms to recover all data post a clean reinstall.

Stellar Phoenix Macintosh Data Recovery is a Mac Disk Recovery tool that ensures safe, easy, and quick recovery of formatted data from Mac OS X 10.3.9, 10.4 Tiger, 10.5 Leopard, and 10.6 Snow Leopard based hard drives. The tool also allows preview of the recoverable data. It is compatible with HFS, HFS+, HFSX, HFS Wrapper, and FAT file systems.

But technology has its failures too. Have you ever tried to fix a scratched disk? Have you ever tried to fix a scratched disc? Is it the same gadget but different name? Well, except for the fact that both of them are circular, they are different – a disk is a magnetic media while a disc is an optical media. This distinction is important because attempting to fix a scratched disk is best left to technical persons while trying to fix a scratched disc can be a do-it-yourself (DIY) project. If you attempt to fix a scratched disk, you might just be doing more harm � it is mechanical damage that you are looking at, not a simple scratch. A professional is best suited to fix a scratched disk than you ever could do. However, trying to fix a scratched disc is easier.

Diy Fix Scratched Disk Or Professional Fix Scratched Disc?

For most people, the two words, disk and disc, have definitely the same pronunciation and the same meaning, and thus are interchangeable. However, they do have different etymologies and distinct technical meanings. It is an important differentiation because how to fix a scratched disk and how to fix a scratched disc are poles apart.

A disc refers to optical media while a disk refers to magnetic media. Discs include audio CDs, CD-ROMs, DVD-ROM, DVD-RAM, or DVD-video disc, while disks include floppy disks, an external hard drive, and even iPod. So before you go about tinkering, be sure you know what it is and what it is not.

There are several recommended ways to fix a scratched disc, in the do-it-yourself tradition. First, you can clean it by using warm water and soap. Second, you can polish it. You can put toothpaste (the baking soda type or the paste type, not the gel type) on a soft; clean cloth. You can even use the humble banana and its peel! Regardless of the polishing agent you use, just remember never to rub in a circular motion. Instead, rub the disc in a radial motion by starting at the disc’s center and then rubbing out to the edge. Third, you can wax the disc. If these three ways fail to fix a scratched disc and the contents are valuable to you, then it is time to contact a professional.
However, attempting to fix a scratched disk is more complicated. Mechanical damage is usually present in a scratched disk. The damage is not as easily fixed by a non-technical person especially as repairing it would involve technical expertise and even software programs and hardware. In this case, we recommend that you fix a scratched disk by bringing it to a professional. Indeed, trying to fix a scratched disk is not one for amateurs, novices, and technophobes.
When you need professionals to do the job of fixing your discs, contact the Disc Repair Services ( They can fix a scratched disc quickly and conveniently, even without going to their office.

How To Wipe Disk Drives, And Why

Data security has become a bigger concern as the information age goes into full swing. Computers are becoming more and more commonplace as versatile tools for a wide variety of tasks and uses. This has made digital storage increasingly the data storage format of choice, since digital information is easily accessed and processed by computers. This has led to a rise in interest in digital information and data storage systems. Apart from developments in hardware technology that allow bigger capacity devices with faster access times, security has also become a prime consideration. Most software and programs nowadays come equipped with varying levels of security options. For instance, it is now possible to protect almost any file with a password such that only those who can provide the correct password would be able to access the information within the file. However, these software security measures would not stand up to dedicated data extraction efforts, in particular those involving the actual physical hardware. Physically securing the hard drive (or other data storage device) under consideration may not always be possible or practical. Another way of ensuring that important data is not placed at risk is to wipe the disk. Simply deleting the contents of a hard disk is not enough to ensure that they are not recovered. In fact, there are software utilities that allow the recovery of deleted data. This possibility is because when a file is deleted, it is not actually overwritten or removed from the hard disk. Instead, a marker is just associated with the file to say that it has been deleted, and the space it occupies on the disk is marked available for use. This means that the data in the file remains on the disk for the knowledgeable hacker to extract and view. Wiping a disk, on the other hand, is a much more thorough process. In a disk wipe, all data to be wiped off is actually overwritten with random data. This eliminates almost entirely the traces that a normal deletion leaves behind, and makes recovery of data practically impossible. (In theory, it would still be possible to reconstruct the data lost after a hard disk wipe, but this would require high-powered microscopes and would proceed much too slowly to be useful!) Performing a disk wipe is facilitated by the many disk wipe programs available. There are many free options, as well as commercial software options, which may differ in terms of functionality and documentation. The majority of these are available online, which makes it quite easy to browse through and find the most appropriate program for the specific task. Some programs are designed for use on a single personal computer, while others may be designed for use on batches of computers. Confidential data that needs to be kept from being exposed may best be hidden by using a disk wipe. This simple additional security measure makes the recovery of deleted data nearly impossible. With the many disk wipe programs available, it is easier than ever to perform a disk wipe, even for casual users, making this a real data security option. Published at:

How And Why To Wipe Disk Drives

Computers have become more widespread than ever, with every business and organization usually relying to some extent on these information machines. They facilitate the performance of many otherwise tedious tasks within any organization, and really help to boost productivity. For instance, there are programs called word processors for creating any sort of printed communication, from letters to memorandums. There are also programs called spreadsheets that can perform calculations and display data and results in tables and graphs. There is also software available for making databases, which are organized collections of data such as transaction information, employee information, and so on. These databases make it easy to store important information in an easily accessible form. Sometimes, confidential information might need to be stored digitally, in some form or other. When this is the case, there are usually built-in security measures to help keep the precious data protected. However, it might arise that a hard disk would be reallocated, or that the computer itself would be transferred to some other use. In this case, it becomes necessary to completely wipe the disk; that is, delete all the information on the disk, along with any traces that might be used to reconstruct this information. This is good computing practice, even for non-critical hard disks. Wiping down a hard disk does not take much effort, nowadays, since there are programs and the like available to do it for you. Getting used to wiping down hard disks to be deleted completely costs virtually nothing in the way of money or effort but pays off in the formation of a useful habit. There are disk wipe programs available designed for big businesses that might need to do it in large batches. These programs have features that make it easier to keep track of the many hard disk volumes to be wiped. Some can even automatically retrieve and store serial numbers, for instance to comply with legal requirements. Users of personal computers may also sometimes find it necessary to completely erase the data on their hard disks. When selling an old computer, for instance, it would be a good precaution to do a complete wipe-out of the data to prevent any possible identity theft. Simply deleting all files (using the current operating system, for example) may not be secure enough. There are known ways to recover data from a hard disk that has not been wiped cleanly enough. The traces of data that remain in some “deleted’ hard disks are sometimes enough to be analyzed and used to reconstruct pieces of information presumed lost. Apart from security purposes, using these disk wipers can also help when reinstalling an operating system. For systems that are heavily infected with viruses and other malicious software, a complete disk wipe and clean reinstall may be the more convenient solution. There are both free and commercial applications available for wiping disks. Commercial ones are of course not free, but usually technical support for these are readily available. It becomes a matter of choice whether to select a cost-free but unsupported disk wipe program over a commercial program, or vice versa. Published at:
