A device driver or software driver is a program that controls and communicates with the hardware device connected to your system. These drivers are operating system specific and hardware dependent. Corruption in device drivers primarily occurs due to improper system shutdown, operating system malfunctioning, software bugs and more. Once the device driver gets corrupted or damaged, you encounter a STOP error message. Two major consequences that you will encounter as a result of the STOP error message are unbootable hard drive and data inaccessibility. To resolve such data loss situations, an ideal solution is to restore your data from the latest backup. However, if no backup is available or backup falls short to restore the required data, If you have no backup then you need to use powerful data recovery software to recover your lost data.

As a practical case, you encounter the below error message when you attempt to start your Windows Vista based computer after installing a new device driver:

“Driver_corrupted_mmpool stop: 0x000000d0 (0x00000008, 0x00000002, 0x00000000, 0x805493e2)”

The four parameters in the above error message are described below: 1st parameter – Memory referenced 2nd parameter – IRQL at time of reference 3rd parameter – 0: Read, 1: Write 4th parameter – Address that referenced memory

Data saved in the hard drive becomes inaccessible after the above error message appears. In addition, you receive the same error message each time you attempt to start your system.

Cause:

The root cause for the occurrence of the above error message is the corruption of the system pool due to damaged device driver. The above error message primarily occurs when the kernel attempts to access invalid memory when the IRQL (Interrupt Request Level) is very high.

Resolution:

To resolve the above error message and access the data, you will need to take these measures:

• Uninstall the Last Installed device driver • Get the latest Drivers and install them on your system • Get the latest Updates on device drivers

However, if all the above measures fail to perform, the best option is to perform clean reinstall of Windows Vista. A clean reinstall of Windows Vista will erase all the data from the selected hard drive partition. To comprehensively recover the data in such circumstances, you need to opt for efficient data recovery software. These data recovery Tools employ advanced scanning methods to recover lost data from a formatted hard drive. Built with intuitive user-interface, automated recovery procedure and powerful features, these data recovery tools are as easy-to-understand and implement.
