A fatal error message at the startup of Windows XP can be caused due to operating system malfunctioning, upgradation of the software, file system damage, metadata structure corruption, malicious software like virus and more. This fatal error message primarily results in unbootable hard drive and inaccessibility of data. To overcome such data loss situations, the best possible way is to restore the data from your latest backup. However, if you have not maintained any backup or backup fails to restore the required data, then you will need to use advanced data recovery applications that can recover your lost data.

Consider a practical case, where you upgrade your system that has a Xircom Rex 6000 PDA (Personal Digital Assistant) attached using the USB (Universal Serial Bus) cradle. After completion of the upgradation process, you may encounter the below error message when you bootup the system:

A Fatal System Error has occurred: 0x000000be (0x80129768, 0x00129121, 0xF96A4754, 0x0000000B)

This type of error message primarily occurs when you use the USB port.

After the above error message is encountered, the system becomes unmountable making all the data stored on your hard drive inaccessible. In addition, you encounter the same error message each time you attempt to start your system.

Cause:

The above error message primarily occurs if you connect the USB cradle for the Xircom Rex 6000 to a computer that is running Windows XP and then start the installation process during the hardware identification phase.

Resolution:

To resolve the above error message, you need to contact the manufacturer that is Xircom for an update of Rex 6000 that is compatible with Windows XP.

However, if the problem persists and the data remains inaccessible, the best option is to reinstall Windows XP operating system. A clean reinstall of Windows XP operating system will erase all the files and folders from the formatted hard drive partition. To recover your lost files and folders from a formatted partition, you need to opt for advanced data recovery software. Such data recovery tools incorporate powerful scanning algorithms for complete recovery and restoration of the lost data. With self-explanatory user interface, to-the-point documentation, largely automated recovery procedure and advanced recovery features, these recovery applications serve as user-friendly data recovery solutions.
