In MS Windows ,RAM has two parts: (1)Page Pool and (2)Non Page Pool. The program code, data pages and cache are stored in Page pool whereas Non page pool is used by some critical system processes.
It helps a lot in enhancing the system performance, but a small mistake in resizing these memory resources can make the files inaccessible on the hard drive. In these conditions, the lost data can be retrieved by using a windows data recovery software.
In case the values of Page Pool and Non Page Pool parameters are not specified correctly, several Windows kernel mode components might not be able to allocate sufficient memory space to work properly. The values of Windows system components are located in below registry key:
“\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management”
Usually these parameters are set to 0, which tells the windows to compute default values for the resource allocation. And any alteration in this value should be avoided to reduce the chances of data loss.
The file system should be capable of allocating appropriate memory to track all the information about opened files and hard drive partitions on behalf of application.
If the memory settings are wrong then there are chances of file corruptions. It may lead to to a critical data loss situation To sort out this problem one needs a windows data recovery software .
The data recovery tools use deep scanning method for the entire hard drive and retrieve all the missing data from it. These programs are easy to use , interactive with graphical user interface and thus no need of technical expertise for the user.

Discussion- Causes of Data Loss and Windows Data Recovery
There is no need to express the importance of data in todays world . It is the most significant wheel of an organization's success journey. For a business firm , loss of data is equivalent to loss of money. However, regular data backup is one of the preventive measures that could be taken to reduce the chances of data loss.
But its also true that no one can assure the complete data safety. In case of data loss problems , Data Recovery software are required to get your data back.
Here are some of the reasons why people neglect doing backups:
Having a regular backup of data is very important. Also there are so many utilities available for automating the data backup. The operating systems are also equipped with some default backup tools like NTBackup in Windows and Time Machine in Mac OS X .
The user can also use a third-party backup utility for effective and absolute backup of your valuable data and avoid need of Windows Data Recovery methods.
However, if you do not create backup, you may face critical data loss situations. Data loss is a very critical situation, that may occur due to various reasons such as logical failure and physical failure.
In windows, the logical failure may occur due to file system corruption, virus infection or hard drive formatting. In such cases, you can get your data recovered with the help of Windows Data Recovery Software .
The system failure can be categorized into two categories- Physical and Logical failure The physical hard drive failure are complicated than logical ones. They may occur after read/write head crash, spindle motor damage, disk controller failure, and so forth. Data Recovery Service experts help you in these cases to retrieve your data from damaged storage media.
But its also true that no one can assure the complete data safety. In case of data loss problems , Data Recovery software are required to get your data back.
Here are some of the reasons why people neglect doing backups:
- You can not understand the importance of data, as you have not yet encountered a critical data loss.
- You do not know the way to create backup.
- You forget to backup data as you do not have any routine for the same.
- Creating backup of large amounts of data is a quite time-consuming task and thus you can not be bothered.

Microsoft Will Issue Out-of-Band Patch to Solve IE Hole
Microsoft is going to release an out-of-band patch to solve the "Aurora" vulnerability. This was the problem which has has struck Internet Explorer. This patch would be released on Wednesday
It has also been mentioned in company's statement that , so far, "very limited, and in some cases, targeted attacks" have been made against Internet Explorer 6. Microsoft had previously concluded that Internet Explorer 6 for Windows XP and Windows 2000 was vulnerable, and also the same issue was found with IE7 on Windows XP and Vista.
It was Aurora vulnerability, the unknown attackers used to hit Google and a number of other Internet companies; those attacks were originally blamed on a hole in Adobe's products, but were later applied on Internet Explorer.
This confusion on the issue prompted the out-of-band patch, George Stathakopoulos, general manager of Trustworthy Computing Security, mentioned in a blog post.
“After giving a significant level of attention this issue has generated, confusion among the customers to protect themselves and the escalating threat environment Microsoft will release a security update out-of-band for this vulnerability," Stathakopoulos mentioned .
"We take the decision to go out-of-band very seriously given the impact to customers, but we believe releasing an update out-of-band update is the right decision at this time," Stathakopoulos added.
Obviously, Microsoft will continue to recommend users to update their browser to Internet Explorer 8, a practice that some businesses may have not taken because of their dependence on older Web applications.

“DRIVER_POWER_STATE_FAILURE” Error Can be resolved
The STOP error takes place due some problem in operating system. This problem stops the OS operations all the functions come to a full stop. The Data becomes inaccessible and and there arise the chances of data loss.
Although it can be solved by re-installation of operating system but thereby chances of data loss are increased. In such case, a recent backup will enable you to restore your lost data. In such situations the backup of data can be very helpful to overcome the problem. However, when when there is no backup then an efficient Windows Data Recovery Software will recover your lost data completely.
An example to diagnose the Operating System failure is:
Suppose you try to shut down your system but the system continues with the shut down screen for a very long time . It shows the symptoms of OS failure and prompts the following error message.:
“STOP: 0x0000009F (parameter1, parameter2, parameter3, parameter4)
DRIVER_POWER_STATE_FAILURE”
The above STOP error message indicates that the drivers are not handling the power state transition requests properly.
Reason behind this behavior:
Here are the possible reasons of it:
How can we solve this problem:
To resolve the above STOP error message, follow the steps below:

Fsutil Does Not Applicable with FAT32 or FAT File System Volumes
In Microsoft Windows operating system, Fsutil is a tool that can be used to carry out several NTFS and FAT file system related operations. These operations include managing sparse files, managing sparse points, extending a volume, or dismounting a volume. Because the Fsutil is an extremely powerful tool, it needs to be used only by the advanced users as improper user of this command may cause data loss situations. In order to retrieve lost data, you are required to go for Windows Data Recovery applications.
In some situations, when you use Fsutil command-line tool with 'query' parameter for checking the status of 'dirty' bit on the FAT32 or FAT file system volume, tool always shows that volumes is not dirty. But in fact the volume is dirty and it can not be accessed. All of the data stored on volume is inaccessible and you are experiencing data loss situations. You need to find out the cause of this behavior and perform Windows Recovery by fixing it to gain access of your data.
Root of the problem:
This behavior of Microsoft Windows occurs because the Fsutil utility doesn't effectively manage dirty bit for the FAT32 or FAT file system volumes. When you try to set dirty bit on the FAT32 or FAT file system volume through Fsutil, you encounter below error message:
"The Fsutil utility requires a local NTFS volume"
The dirty bit is the bit in boot sector (in case of FAT32 or FAT file system volumes), or in MFT (in case of NTFS file system volumes), which is tested when Microsoft Windows boots up. The bit is tested to decide whether the corruption is detected in file system. If the volume has dirty bit, Autocheck runs automatically for correcting errors on volume.
On the NTFS file system volumes, dirty bit is generally set only when file system detects the potential damage. In such situation, an entry is made in System Event Log of Windows.
In such situations, Windows Data Recovery Software come for your help to retrieve lost data. The applications have simple graphical user interface to provide easy windows data recovery. They throughly scan the whole media and extract all lost, missing, and inaccessible data from it. With read-only behavior, they are safe to use as they do not alter original data on the drive.

Data Loss in Windows if MFT size crosses 4 GB Size
The metadata about each data and metafile on the NTFS partition is stored at MFT ie; Master File Table , in NTFS file system . So, MFT is an important data structure for NTFS file system. But, if the entries exceeds 4 million, there is a chance MFT damage and you come across also data loss situations. In such situations, Windows Data Recovery is required to get your valuable data back.
If we store more files on the NTFS file system partition which already has over 4 million files, you may encounter file corruption. This behavior might be shown in any of the below given ways:
After this , some of your significant files or directories may become inaccessible and you come across data loss.
Reason of this problem:
This issue arises when the size of MFT goes beyond 4 GB in size. This may also happen happen if you store over 4 million files on your Windows hard drive. When you remove any file whose master file table entry is beyond 4 GB point in such circumstances, an error in the calculations results into the incorrect entry to be pointed as available.
If the same entry contains information about other files, and you add new files to partition just after deleting the files, entry can be re-used resulting into the file referenced to be lost.
The Windows Data Recovery Software can be used to extract lost data. The Windows Recovery tools scan the affected drive with advanced scanning techniques and recover windows data from it. With read only conduct and user friendly interface , these applications are absolutely safe and easy to use.
If we store more files on the NTFS file system partition which already has over 4 million files, you may encounter file corruption. This behavior might be shown in any of the below given ways:
- Deleted files are not removed from the drive. They continue to remain at the same location.
- Files and directories that you haven't removed can not be accessed any more.
- You encounter a pop-up messages, which states that the hard drive or its data structures are damaged and you need to run Chkdsk to fix the problem.
After this , some of your significant files or directories may become inaccessible and you come across data loss.
