'PAGE_FAULT_IN_NONPAGED_AREA' error in Windows

Although Windows is one of the most popular operating system but it has not been able to escape the bugs and problems that come bundled with any software package. The windows vista users usually encounter problem while booting. I have also faced a major problem last week, when I tried to boot my system and found my data totally inaccessible. After trying all my efforts , when was unable to get them back , I had to use Windows data recovery tools as I did not have backup of all my data saved on my hard drive.

After the splash screen, during startup, there appeared a black screen which had a moving progress bar. Along with this, an error message also flashed:

“A problem has been detected and Windows has been shut down to prevent damage to your computer.

CLFS.SYS

PAGE_FAULT_IN_NONPAGED_AREA

If this is the first time you’ve seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup options, and then select Safe Mode.

Technical information:

*** STOP: 0x00000050 (0x8AFBF028,0x00000000,0x84E2C363,0x00000000)

*** CLFS.SYS - Address 0x84E2C363 base at 82e1b000 Datestamp 4549acbc”

Cause:
After too much of studies and R&D I came to know that, this error message appears when the CLFS.SYS file is corrupt or damaged. This error is followed by non booting of your Windows Vista, and ultimately to inaccessibility of the hard drive data.

In such situations, it becomes almost impossible to retrieve your data unless you have a backup. Otherwise you need to use 'Startup Repair' options to get rid of system booting problems.

And if this also fails, then you'll need to reinstall your Windows Vista to ensure your system starts to run properly. That done, to recover your data, you need to use effective windows recovery software
