FAT Table Needs to be Updated Regularly to Protect Your Data

Image via Wikipedia

Microsoft Windows operating system uses file system to organize, manage, and manipulate data on your Windows hard drive. It basically supports two major file systems- FAT and NTFS. Both these file systems have different variants. FAT is so far the most simple file system supported by Microsoft Windows operating system. It is characterized by FAT (File Allocation Table) that is actually a table, which resides at very top of Windows partition. Under some circumstances, this critical Windows data structure gets damaged due to virus infection and unexpected system shutdown like situations. At this point, entire partition becomes inaccessible and needs of FAT data recovery arise.

From file system and data security point of view, FAT file system preserves redundant copy of the file allocation table. You can restore the backup copy of FAT in case the original table gets damaged. Furthermore, the root directory and file allocation tables must be stored at a fixed location on hard drive so that operating system can correctly locate the boot files and boot up your system properly.

A FAT file system partition is allocated into the clusters. The size of clusters is determined by size of partition. When you create a file on FAT partition, it creates an entry in directory and establishes the first cluster that contains data. The entry in file allocation table either points to next cluster on the partition or indicates that it is laster cluster of file.

It is pretty important to periodically update the file allocation table of FAT file system partition. However, it is a very time consuming process. The process is time consuming because read/write heads needs to be repositioned to logical track zero of the drive every time when you update it. If you do not regularly update this metadata structure, it may get damaged and lead to severe data loss.

Data loss is something that cannot be accepted at any cost and may affect your professional as well as personal life. At this point, FAT recovery is required to retrieve your data and save your business.

FAT recovery is best possible using advanced and powerful third-party applications, known as FAT data recovery software. They employ highly advanced scanning methods to perform in-depth scan of entire disk and extract all inaccessible data from it.

How to Recover Lost Data from A Windows Hard Drive Image?

In Microsoft Windows operating system, you can create image of your hard drive partition, selected region of the hard drive, or entire hard drive using third-party applications. You can use disk imaging process to create complete backup of your valuable data and prevent data loss situations. However, in some situations, the disk image created on NTFS file system drive may get damaged and it can not be accessed. In such situations, you come across severe data loss and require NTFS data recovery to work around the problem.

A hard drive image or disk image is a single file that contains all the contents of source storage media, such as hard drive, CD, DVD, USB drive, and memory card. The disk image is generally a sector-by-sector copy of your Windows hard drive or other storage media, which can be mounted like a hard drive partition and accessed. Some of the disk imaging tools may also remove unused space of the hard drive when they create image of the disk.

Under some critical circumstances, you can not access a hard drive image from NTFS file system drive. You may also come across numerous error messages at this point. Such issues are generally caused by any of the following reasons:

• Virus infection- If the virus has infected disk image or its significant data structures, then Windows can not recognize the file and access its contents. The data become inaccessible in such cases and you face severe data loss situations.

• Damaged storage media- If the storage device, on which disk image is stored, it corrupt, the file can not be accessed. You must first perform NTFS file recovery to fix the damaged storage media, before the file is actually recovered.

• File system corruption- If the file system of your disk image is corrupt, Windows can not identify it and read data from it.

In case source drive is corrupt and the disk image is also inaccessible, serious data loss issues take place. In such critical situations, NTFS partition recovery come for your help.

The NTFS data recovery applications are powerful enough to systematically scan entire hard drive and extract all lost, missing, and inaccessible data from it. They are totally safe and easy to use with non-destructive behavior and interactive graphical user interface.

Image via CrunchBase

Are you getting 'Event ID 55' while booting your Windows 7 operating system-based computer? Is your Windows 7 hard drive unreadable and unusable due to corrupt file system structure? Well, it is a very critical situation that renders your system totally inaccessible. It is resulted by various factors like sluggish operating system, missing/corrupt system data structures, and hard drive logical structure errors. The problem generally occurs on NTFS file system partitions and leads to serious partition loss situations. In order to recover lost data and hard drive partitions at this point, NTFS data recovery is required.

As a practical instance of this behavior of Microsoft Windows 7 operating system, you may run across the underwritten error message when you try to boot up your computer:

“Event Type: Error
Event Source: NTFS
Event ID: 55
Description:
The file system structure on disk is corrupt and unusable. Please run the chkdsk utility on the volume ”

If you run Chkdsk.exe utility to fix the issue, process gets interrupted halfway. The drive remains unusable and severe data loss occurs.

What causes 'Event ID 55' in Microsoft Windows 7?

The above problem may occur if the Windows hard drive partition or its file system is damaged. The corruption can be caused by any of the following reasons:

· You Windows hard drive has damaged data structures.

· The Input/Output requests, which are issued by file system to hard disk subsystem, may not have completed successfully.

What You need to do...

Try out any of the below methods to fix this problem-

Check state of NTFS file system and then repair it if required:

· Type chkntfs : at command prompt.

· If it says 'drive is dirty' then run chkdsk against it, otherwise the volume is not corrupt and no repair is required.

You can also try running the Chkdsk.exe utility manually to check out the integrity and consistency of the Windows hard drive.

If the above processes fails, you can make your drive functional by formatting it and reinstalling operating system. However, it is not safe from data point of view and requires NTFS file recovery to retrieve data, if applied.

You can successfully recovery your lost data using NTFS partition recovery software. The applications are particularly invented to systematically scan entire hard drive and recover lost NTFS file system partitions. NTFS data recovery with these tools is quite safe and easy.

Pros and Cons of Disk Write Caching in Microsoft Windows

Microsoft Windows operating system allows you to enable or disable the disk write caching to improve the system performance. It makes the disk writes more effective. However, in some situations, disk caching may interfere with the working of various Windows applications. In such cases, you may need to disable the write caching to use these applications. Sometimes, disk write caching may cause serious problems if your computer face power failure or system crash like situations. You may lose your hard drive partitions and valuable data at this point and need Partition Recovery Software to work around the issue, if there is no backup in place.


What is Write Caching?


When you save a file on Windows hard drive, recent versions of Windows operating system take a note of this fact that you want to save a file on hard drive. They save this information somewhere else in computer memory, and write this file to hard drive later. After a file is written to the hard drive, cache sends an acknowledgment to the operating system that data is written to the hard drive and it can be removed from cache.

How to Enable Disk Write Caching?

    * · Right-click the My Computer icon, and select Properties.
    * · Click Hardware tab.
    * · Click the Device Manager.
    * · Click + (plus sign) next to Disk Drives for expanding it.
    * · Right-click the disk on which you need to enable write caching, and click Properties.
    * · Click Disk Properties tab.
    * · Click Write Cache Enabled check box for selecting it.
    * · Click the OK button.

When you enable the write caching on a Windows hard drive, you may come across the below warning message, which indicates possibilities of data loss:

“By enabling write caching, file system corruption and/or data loss could occur if the machine experiences a power, device or system failure and cannot be shutdown properly.”

If you face any sort of failure on your system that has disk write caching enabled, due to power outages, improper system shutdown, or system crash, file system corruption and partition loss may occur. In such cases, ntfs data recovery becomes need of hour.

Recovery is best possible using advanced and powerful applications, known as NTFS file recovery software. Such data recovery tools are totally safe and easy to use with non-destructive nature and rich graphical user interface.
