Error message “FAT FILE SYSTEM”

FAT (File Allocation Table) file system provides a mapping between the logical storage and physical location of the hard drive data. It contains an entry for all files stored on the hard drive that restrains the address of the file’s initial cluster. Corruption of FAT file system primarily occurs due to operating system corruption, improper system shutdown, malicious software like virus and more. After the FAT file system corruption, the data stored in the hard drive becomes inaccessible. In such situations, if no backup is available, you need to recover the lost data by using efficient Data Recovery Software.

For example, if you have two different drives in your system – FDD (Floppy Disk Drive) and MO (Magneto-Optical) drive – that have non-unique volume serial numbers and similar files, you might encounter the below STOP error message:

“STOP 0x00000023 (Parameter1, Parameter2, Parameter3, Parameter4)

FAT_FILE_SYSTEM”

The four parameters in the error message differ with computer’s configuration.

Cause:

This above error message mainly occurs because the FAT file system driver is unable to recognize the two drives and hence the media in your system. As there are various differences between the types of these media, you encounter the above error message. Another major cause for the error message can be physical disk problem or IRP (Input/output Request Packets) corruption.

Resolution:

To resolve the above STOP error and access the data, you should take these actions:

• Make sure that there are no file system integrity issues by running chkdsk(Checkdisk utility) command with different switches as /r and /f.
• Stop all file system filter drivers like backup utilities, virus scanners or firewall software.
• Update all disk, tape backup, CD-ROM or removable device drivers to their latest versions.
• Verify the file properties of the Fastfat.sys file to ensure that it matches the present version of the operating system.
• Apply the Hotfix solution provided by Microsoft.

However, if all the above steps fail to resolve your problem, then the best possible solution is to reinstall the operating system. A clean reinstall of the operating system will delete all data from the selected hard drive partition. In such situations, to completely recover the data, you should use effective Data Recovery Software.

Such Data Recovery Tools perform complete recovery and restoration of lost data from a formatted hard drive. These user-friendly Data Recovery applications can be easily implemented due to their largely graphical interface and to-the-point documentation.

Rectifying “STOP: 0x00000006” Error Message in Windows XP and 2000

The term STOP error is primarily used by NT-based Windows operating systems. These errors occur after the operating system encounters critical issues due to hardware or software based problems. Such problems can be summarized as operating system corruption, file system issues, driver incompatibility, virus infection etc. One of the common software corruption issues responsible for the occurrence of a STOP error message is corruption of device drivers. A STOP error message caused due to the above problem results in unmountable boot volume and data inaccessibility. In such situations, to successfully restore the lost data, you should use an updated backup. In case of no backup availability, backup not up-to-date or corruption, you need to use advanced Windows Data Recovery tools. 

As a practical instance, while starting a Windows XP or Windows 2000 based computer, you can receive any of the below error messages:

“STOP: 0x00000006

Beginning dump of physical memory
Physical memory dump complete.

Contact your system administrator or technical support group for further
assistance.”

Or 

“STOP: 0x00000006 (0x00000000, 0x00000000, 0x00000000, 0x00000000)

INVALID_PROCESS_DETACH_ATTEMPT”

The operating system bootup process gets halted and data saved in the hard drive becomes inaccessible after any of the above STOP error messages appear. 

Problem Might be:

• Corruption or damage of device drivers. A device driver can be damaged due to improper system shutdown, operating system malfunctioning, software bugs and more.
• The error message can also occur if Windows operating system incorrectly queues a kernel Asynchronous Procedure Call (APC) function, also known as a completion routine.

Most Possible Solution:

For complete resolution of the above STOP 0x00000006 error message, you need to follow these steps:

• Use “Last Known Good Configuration” option from Windows Advanced Options menu to boot your system as it is a special mode to undo new registry and driver changes.
• Rollback device driver to version prior to your driver update.
• Use System Restore to undo new computer alterations.
• Apply the Hotfix solution offered by Microsoft.

However, if the above measures fall short of rectifying the STOP error message, then you need to go for a clean reinstall of the operating system. A clean reinstall erases all the partition data and installs a fresh copy of the operating system. For systematic recovery of all the previously saved files, you need to use powerful recovery tools. Such data recovery tools perform absolute scan on the formatted hard drive by incorporating high end scanning algorithms. With highly interactive graphical user interface, these data recovery tools are easy to understand without any prior technical knowledge.

Solution to Software and Hardware caused data loss issues

Data loss occurs due to two types of causes: Logical issues and Physical issues. Data loss may also occur due to various other reasons like cabling issues, user error, malicious intent (commonly termed as sabotage), vandalism etc. So, you need to understand these problems first. However, in both types of data loss scenarios, unavailability of valid data backups requires Data Recovery Tools to recover lost data.

Logical Data Loss

Logical data loss occurs when software related errors affect data integrity and system hardware remains fine. It occurs due to damage of logical components like file system, operating system etc. The reasons of logical data loss are:

• Invalid directory entries
• Corruption or deletion of file system table
• Damage of integral file system metadata structure
• Unintentional deletion
• Operating system crash
• Accidental partition/volume formatting

Data can be recovered in all the above cases, unless it has not been overwritten. Operating system uses referencing provided by file system table to locate a file in the data area. This file entry points towards the location, where a file is actually stored. But when any of the above incidents take place, operating system can lose the capability to locate information. It is due to the fact that corresponding file entry gets deleted, though original file remains safe in the data area of the file system. That’s why users think that their precious data has got lost. However, locating and recovering data in such cases is complex but it is possible. The key to such daunting problems is provided by Data Recovery software, which can safely scan affected drives and recover lost, deleted or formatted data.

Physical Data Loss

Unlike logical data loss, physical data loss occurs when hard disk suffers physical damage to extent of data inaccessibility. A hard disk consists of several moving components and electronic circuitry. The reasons behind physical data loss are:

• Read/write head crash
• Spindle motor damage
• Spindle twisted or bent
• Actuator crash
• Head arms damage
• Water/fire damage
• Platters misalignment
• PCB (Printed Circuit Board) malfunction

In these cases, Data Recovery is possible, unless there hasn’t been any physical harm to the platters or their magnetic material. The physical functioning of hard disk is dependent upon its internals. However if any of these components experience failure, data remains intact on the hard drive platters. To recover the inaccessible data, you need to get the damaged hard drive internals (viz. read/write head) repaired or replaced as per the case. The process involves implementation of several advanced and modern component level techniques that involves isolating hard drive platters from environmental factors like heat, humidity, dust particles etc. All these requirements are fulfilled by drive recovery service which is provided by experts. The hard drive recovery professionals extract optimum amount of inaccessible data from physically failed hard drives.

0x000000c5 Error Message during Windows XP bootup

A STOP error message can come during Windows bootup or after a user logs on and performs various tasks (as driver update, file download from internet and more). STOP errors halt the normal functioning of your computer system. A STOP error message appears only on Windows NT based operating systems (as Windows 2000, XP, 2003 & Vista) and can be caused by both software and hardware issues. In most cases, a STOP error message is usually identified by an 8-digit hexadecimal number. The major consequences of a STOP error message are unmountable volume and inaccessible data. To overcome these data related issues, the most effective way is to restore data from latest backup. However, if you have not maintained any backup or it falls short of restoring the lost data, then you should use advanced Data Recovery application.


Consider a practical instance, where you install Ahead Nero 6.3.1.17 on your Windows XP-based computer. After the installation process is complete, you restart the system. When you restart the system, you encounter the below STOP error message:


“Stop Error: 0*000000C5 (parameter1, Parameter2, Parameter3, Parameter4) Beginning Dump of Physical Memory!”

The above error message might also appear as:

“0x000000C5: DRIVER_CORRUPTED_EXPOOL”


Data stored in the hard drive becomes inaccessible after any of the above error messages appear. In addition, you encounter the same error message each time you attempt to boot the system.


Reason:

The core reason behind occurrence of the above error message is corruption of system pool by device drivers. To prevent the above error message, always install an updated version of the software available on manufacturer’s website.


Solution:


To resolve the above issue and access data, you should take these actions:

• Uninstall Ahead Nero 6.3.1.17 from your system.
• Install the latest service pack of Windows XP operating system.

However, if you still encounter any of the above STOP 0xC5 error messages, then you should reinstall Windows XP operating system. A clean reinstall will erase all data from the selected partition. For complete recovery and restoration of lost files and folders after formatting the drive, you should use advanced data recovery software. These tools incorporate effective scanning algorithms to recover and restore the lost data from a formatted hard drive.

STOP Error Message at Windows XP startup

A device driver (also known as software driver) is a computer program that allows higher level computer programs to communicate with a hardware component. To interact with the hardware component, the device uses communications subsystem or computer bus. Few main reasons that result in the corruption of device drivers are user error, malicious software like virus and more. In most cases, the outcome for a corrupted driver results in a STOP error message. After you encounter the STOP error message, you may not be able to boot the system. Moreover, the data stored in the hard drive becomes inaccessible. In such situations, you need to recover your data from the latest backup. But, if you have not maintained any backup or the backup fails to deliver the required data, then you need to use advanced Data Recovery Software.

When you attempt to boot a Windows XP based computer, you receive the below error message:

“STOP: (parameter 1, parameter 2, parameter 3, parameter 4) SESSION3_INITIALIZATION_FAILED”

You encounter the same error message each time you attempt to start your computer system. After the above error message appears, the data saved in the hard drive becomes inaccessible.

Cause:

The primary reason for the occurrence of the above error message is device driver corruption.

Resolution:

To resolve the above error and access the data, you should firstly remove the additional hardware attached to the computer. After doing so, you need to use the Windows XP operating system disk to view all the contents of Windows folder named drivers (‘%windows%\system32\drivers’). If you find any files such as TDSS????.sys or TDSS????.DLL, you need to remove them and restart the system.

However, if you receive the same error message when you restart your system, you need to go for clean Windows reinstall. A clean reinstall of the operating system will erase all the data saved in hard drive. To completely recover and restore the lost data, you need to use efficient Data Recovery tools.

These Data Recovery tools incorporate powerful scanning methods to provide comprehensive recovery of lost data. Such utilities provide simple user interface with advanced features for instant or in-depth recovery.

Partition Loss due to Invalid Boot configuration

Most of the computer users divide there hard disks into more than one partitions to use the space more efficiently viz. to store and search something specific. You can use different operating systems on a single computer by installing them into different partitions. However, you might encounter an error message when you attempt to boot an operating system. Such error messages halt the booting process and make the data saved in the partition inaccessible. To access the data in a systematic manner, you need to restore it from an updated backup. But if you have not created any backup or the backup fails to restore the required data, then you need to perform Partition Recovery by using effective Partition Recovery Software.

Consider a scenario, where you encounter the below error message during Windows XP bootup:

"Could not read from the selected boot disk. Check boot path and disk hardware."

After the above error message appears, the bootup process gets halted and the data saved in the hard drive becomes inaccessible.

Cause:

Two primary causes behind occurrence of the above error messages are:

· Corrupt, missing or incomplete Boot.ini file,

· Invalid partition path in Boot.ini file

Resolution:

To resolve the above error and regain access of your precious data, you need to follow these steps:

· Restore your system to last successful logon by using “Last Known Good Configuration.”

· Run Windows Setup from the operating system CD provided by the computer manufacturer.

· On ‘Welcome to Setup’ screen, press R to open “Recovery Console”

· Restore your system to previously saved configuration

However, while applying the above measures, you may encounter these issues:

· While opening “Recovery Console”, you receive a command prompt without any log-in option.

· While using the operating system CD, the installation remains incomplete

· While trying to access Windows folder, you might encounter an “Access Denied” error message.

If you encounter any of the above issues, you need to reinstall the operating system. A clean reinstall of the operating system will delete all the saved data on the hard drive partition. In such situations, you need to perform Partition Recovery using powerful third-party tools. Such Partition Recovery utilities recover data by using advanced effective scanning methods. With their user friendly and interactive user interface, you can easily understand these applications.

Resolving 0x80071ab0 Stop Error Message in Windows Vista

Windows Preinstallation Environment (Windows PE) is a lightweight version of Windows Vista, XP or 2003. It is mainly used for deployment of servers and workstations. It controls the early boot process and comes with Windows Automated Installation Kit (WAIK). However, you might encounter a STOP error message after creating a Windows PE image file on a hard drive. Various factors responsible for occurrence of a STOP error message can be FAT file system (due to Windows Vista incompatibility), operating system file corruption, malicious software like virus etc. The data saved in the hard drive becomes inaccessible once you receive a STOP error message. In such situations, if there is no backup available, you need to use advanced and powerful Data Recovery Software.

As a practical scenario, you create a Microsoft Windows PE image file on your Windows Vista based hard drive. However, when you attempt to add a package to your image file, you encounter the below error message:

“0x80071ab0”

After the above STOP error message appears, the data saved in the hard disk becomes inaccessible.

Cause:

The root cause for occurrence of the above error message is that you have not formatted your hard drive with NTFS file system.

Resolution:

To resolve the above problem and access the data, you need to convert the file system of your hard drive to NTFS. To do so, you need to follow these steps:

1. Click on the Start button, type command in the Start Search box and press Enter
2. Right-click Command Prompt in the Programs list, select Run as Administrator
3. If you receive a UAC (User Account Control) prompt to enter Administrator password, enter the password and click Continue
4. Type the below command at the command prompt and press ENTER:

convert drive letter: /fs:ntfs

But, if you still encounter the same error message after completion of file system conversion, you need to go for a clean reinstall of Windows Vista. A clean reinstall erases all the files and folders previously stored on the hard drive. To successfully recover and restore the lost files, you need to use effective File Recovery application. Such recovery applications use high-end scanning methods to provide absolute Data Recovery, even from a formatted hard drive. With their easy-to-understand interface, these applications act as user-friendly tools to recover lost data files.

Firmware Corruption and Data Recovery

In general terms, firmware is the set of instructions i.e. program that is embedded on an electronic device and controls it. For hard drive, this is a program that is built into it and keeps control of it. It is meant to run the hard drive as per the logic required.

It is simply defined as software on hardware. It is a software program which is found on PCB (Printed Circuit Board) flash memory. The typical functions of firmware include configuring hard drive while startup, interacting with hard drive’s components while working and correctly powering down hard drive. If the firmware gets corrupt, hard drive will become inaccessible. In the absence of data backup, it causes data loss and Data Recovery service becomes necessary.

While the firmware is corrupt, the system can not access hard disk data. As the nature of the issue is, the corrupt firmware needs to be reprogrammed by low level programming techniques. These techniques usually require experienced programmers.

The symptoms of hard disk corruption differ as per the extent of damage.

• If the extent of damage is high, BIOS may fail to recognize such hard drive.
• In case of partial corruption, system may run slow or hang while booting.

Low-level reprogramming of firmware is the solution to correct the issue. Data Recovery experts affirm that it is a safe procedure, if done properly and by following the proper guidelines. Such failed hard drives need to be checked through suitable procedures that include safe dissection of hard drive in Clean Rooms. Clean Room surroundings give an appropriate lab environment that is completely free from moisture, dust, ESD (Electrostatic Discharge), high or low temperature and pressure etc. It is meant for environmental problem free work routine so that the sensitive disk internals remain safe.

Hard Disk Recovery is performed for extracting data in other cases also that can be mechanical or electronic failures. Data in such cases is recovered using definite procedures, which involve replacing the damaged internals and applying careful and technical data extraction processes. Recovery service is the solution in each physical failure case.

Error Loading Operating System at Windows XP Startup

Windows XP operating system upgrade to Service Pack 3 (SP3) enables you to experience new features and advantages. The SP3 consists of security updates, hotfixes and certain out-of-band releases. During the upgrade process, an error message can appear when Windows fails to boot properly. Such error messages occur at a point between the System BIOS running checks on the hardware devices and the actual loading of operating system.

In such situations, the data saved in the hard drive becomes inaccessible. To access your data, you need to restore it from updated data backup. However, if no backup is available or the backup fails to restore the required data, you need to recover all lost data by using efficient Windows Data Recovery Software.

As a practical instance, when you restart your computer system after upgrading Windows XP, you encounter the below error message:

“Error loading operating system”

The user encounters the same error message each time he attempts to boot the operating system. After the above error message appears, the data stored in the hard drive becomes inaccessible.

Cause:

The above error message mainly occurs when your system BIOS does not properly manage the capacity of the hard drive on which you are installing a new version of Windows XP by upgrading it.

Resolution:

To resolve the above problem and access the data, you need to make sure that you are incorporating the latest BIOS for your computer. To check the BIOS information, you need to firstly check the computer’s manual. After doing so, you need to contact the computer manufacturer to obtain and install the latest BIOS update that is currently available for your system. The process to upgrade BIOS on your system is known as flashing.

If you encounter the same error message even after installing the latest BIOS update, it means that the problem is not due to BIOS. In such situations, Windows Data Recovery applications come to rescue. These applications use influential scanning methods for complete and orderly recovery of inaccessible data from hard drive. With highly graphical user interface, these recovery utilities are easy to understand without any prior technical knowledge.

Error Message after installing Windows XP on a Windows Vista system

The dual boot systems enable you to use features of two different operating systems on a single computer system. A user can install two different operating systems starting from the older one. It is preferred to partition the hard disk first and create at least two partitions. However, problems might occur when you install an older operating system like Windows XP on a Windows Vista system. In such situations, you receive an error message at system start up and data saved in the hard drive becomes inaccessible. If you have not maintained any updated data backup, you need to use advanced Data Recovery Software to access the data.

Consider a practical scenario, where a user has a Windows Vista based system and he installs Windows XP on a different partition. After the installation process is complete, when the user restarts the computer, he encounters the below error message:

"A disk read error has occurred. Press CTRL+ALT+DEL to restart."

The user receives the same error message each time he restarts the computer system after pressing CTRL+ALT+DEL key combination. After the above error message appears, the data saved in the hard disk becomes inaccessible. The main cause of the above error message is that the user has installed a version of Windows that is older than Windows Vista. The problem arises because the Setup process in the previous version of Windows attempts to overwrite the boot sector on the main Windows Vista partition.

Resolution:

To resolve the above error and access the data saved in the hard drive, the user needs to follow these steps:

• The user should install earlier Windows XP on the primary boot partition.
• Then the user needs to install Windows Vista on a new partition.
• If the user wants to start from more than one Windows operating system, install the earliest version of Windows first, and then install the later versions in their order of release. Here, the user needs to firstly install Windows XP operating system and then Windows Vista operating system.
• The user needs to install each operating system according to the standard installation procedure.

To access the data saved in the hard drive, the user needs to use powerful Data Recovery applications. Data Recovery Software employ effective and high-end scanning methods to recover and restore inaccessible data from hard drives.

Winload.exe Corruption and Recovery

Windows Vista boot loader is termed as Winload.exe. The file plays a significant role in Windows Vista boot process, similar to what is played by NTLDR in earlier versions Windows NT Core operating systems. Hence it can make system unbootable if gets corrupt or damaged, which may eventually need Data Recovery. Windows Boot Manager invokes and uses the file to load device drivers and ntoskrl.exe (Windows kernel image).

Winload.exe Corruption

While Winload.exe is missing or corrupt, system fails to boot. The file can get corrupt due to software or hardware change, corrupt BCD (Boot Configuration Data) entries or unexpected shutdown. Also users report the same issue after they use incompatible partition resizing utilities for Windows Vista partitions. Windows Vista uses a different partitioning scheme (with respect to space required before primary partition) as compared to Windows XP and earlier Windows versions. The error reported in this case can be as follows:

File: \windows\system32\winload.exe

Status: 0xc000000f

Info: “The selected entry could not be loaded because the application is missing or corrupt.”

Solution

1 As the first option, we can use Windows Recovery Environment in order to repair. We can make use of Startup Repair option in System Recovery Options dialog box by choosing the operating system to repair. The option can correct most of the startup issues. Alternatively command prompt can be used.

2 Windows Recovery Environment can be used to choose and recover the system to an appropriate restore point. The option will get the system to a working state.

Note: The option is applicable only if System Restore was enabled earlier.

3 If above attempts fail to resolve the issue, we need to reinstall Windows Vista. Thus, it is recommended to backup all data by attaching the hard disk to another working system. Formatting a hard drive deletes all data and if backup fails in this case, Data Recovery Software will be required. Hence data backup status must be checked once the user completes the backup procedure. It will be more cautious to look if media actually gives required results.

About Data Recovery Software

These are the specialized tools to recover lost data. The applications are mostly implemented when backup fails or doesn’t exist at all. In such cases, Data Recovery Software can recover information from affected media. Such advanced Data Recovery applications don’t compromise with data safety and keep your valuable files intact. This is due to their read-only nature. Due to their interactive interface, they serve the purpose of user friendliness along with high end File Recovery.
