Viruses and worms are major threats to your critical files on a Microsoft Windows operating system. Sometimes when you start your computer, you might find that most of your .MPG, .MP3, .MPEG, .RAR, .AVI and several other types of multimedia and application files are missing. This is a very critical situation of file where you may not come across the cause of file loss at first sight. Non-technical users could not consider how the files have got deleted.

In such circumstances, to retrieve lost files or your partition, you are required to opt for Partition Recovery solutions. When the above situation occurs, you might find out that all of the hardware and software resources of your computer are working fine. The system starts up properly and you can easily access all of the files and folders, which are available on the hard drive. But you can not see multimedia files.

Root of the issue Such sort of file loss issues are caused by the viruses and worms. There are a number of malicious programs, which are designed to destroy or damage specific type of data files. One such kind of harmful and damaging worm is the W32.Nopir.c.

W32.Nopir.c is an extremely destructive and powerful worm, which spreads via some kind of file sharing tools such as Kazaa, Gnucleus, eMule and Morpheus. Such worm lowers the system security settings and then deletes .MP3, .AVI, .MPG, .RAR, .MPEG and all other types of multimedia files.

This infection would eventually result into serious nightmare of partition file loss and thus you are required to opt for Partition Recovery methods.

Resolution

In order to get your lost files back, you are suggested to restore the files from most recent backup of your files. Backup is the most excellent solution to prevent file and partition loss situations. But in case if you do not have backup or the backup is not updated, then you need to use Partition Recovery Software to retrieve lost files from affected Windows storage media. These are powerful and advanced third party tools, which thoroughly scan whole hard drive and extract all of the recoverable files from it. These tools have graphical user interface with self-descriptive features and thus allow you to have quick and easy recovery.

The Partition Recovery Software does not alter the original contents of files as they have read-only conduct. Stellar Phoenix Windows Data Recovery is the most advanced and effective tool to retrieve all sorts of lost files. This software recovers lost, missing and inaccessible files from FAT32, VFAT, NTFS and NTFS5 file system partitions. It is designed for Microsoft Windows 7 RC1, Vista, 2003, XP and 2000.

STOP errors are very common in Microsoft Windows operating system. These errors might be caused by software malfunction, incompatible hardware drivers and other similar reasons. When a stop error occurs, Windows stops responding and you get an error with some codes on a blue or black screen. When a stop error occurs, the system become unusable and all of the hard drive partitions become inaccessible. This behavior might cause partition loss in some cases and require Partition Recovery to be sorted out.

In a practical scenario, when you attempt to start Microsoft Windows XP computer, you might come across any of the below given STOP error messages:

STOP: 0xc000026C [Unable to load device driver] DriverName

Or

STOP: 0xc0000221 [Unable to load device driver] DriverName

Or

STOP: 0xc0000221. Bad image check sum, the image user32.dll is possibly corrupt.

The header check sum does not match the computed check sum. Here the DriverName is name of device driver file which is faulty. At this point all of your hard drive partitions become inaccessible and you need to find out the cause of this behavior and sort it out by carrying out Partition Recovery.

Grounds of this problem

This issue with your Windows computer might take place if any of the below given conditions are true:

The User32.dll file of your Windows system is either missing or corrupt. Any device driver (.sys) file is either damaged or missing. The missing or corruption file is possibly a driver file, which the alert message mentions.

Resolution

In order to fix this issue, use appropriate solutions for specific symptoms. If the problem is due to damaged or missing device driver, user Windows Recovery Console for replacing damaged or missing driver file. To do so, you will need Windows Installation CD. On the other hand, if the problem is due to damaged or missing User32.dll file using Windows Installation CD. But in some cases, this process might require in-place upgrade of Windows that requires formatting of hard drive and removes all the hard drive partitions, resulting into critical partition loss situations.

You can handle such cases easily using Partition Recovery Software. These applications use efficient scanning mechanisms to methodically scan entire hard drive and retrieve lost Windows partitions. The Partition Recovery Software are quite easy to use and always perform safe recovery.

Stellar Phoenix Windows Data Recovery is the most excellent solution for all your partition loss problems. It recovers all FAT32, VFAT, NTFS and NTFS5 file system partitions. This software is designed for Microsoft Windows 7 RC1, Vista, 2003, XP and 2000.

In Microsoft Windows operating system, Chkdsk is a command-line utility to verify logical integrity of the file system and hard drive. When the Chkdsk utility come across any logical inconsistencies with the file system, it takes corrective actions for repairing the file system and make your system working again. But in some situations, interruption to the Chkdsk process may damage the drive and lead to serious data loss situations. In such circumstances, you are required to go for Windows Data Recovery solutions to get your valuable data back from damaged media.

In Microsoft Windows 2000 operating system, two new switches (parameters) are added to the Chkdsk utility. Such switches allow you to effectively manage the downtime obtained by running the Chkdsk or Autochk.

The Chkdsk parameters, which are added in Microsoft Windows 2000 are /I and /C. These switches are only applicable if the target disk has NTFS (New Technology File System) file system format. Every switch leads Chkdsk routine to bypass a few actions, otherwise it takes to validate integrity of the NTFS file system data structures.

The code, which actually verifies when the Chkdsk runs online, resides in the utility DLL (Dynamic Link Libraries) like Ufat.dll and Untfs.dll. The verification routines, which are invoked by the Chkdsk utility, are same ones raised when the volume is verified using GUI (Graphical User Interface) offered by Disk Administrator or Windows Explorer.

Use of /I and /C switches may cause your volume remaining damaged even after the Chkdsk completes successfully. You are not recommended to use these switches except the situations where the system downtime has to be kept minimum. Both these switches are designed to be applied on exceptionally large hard drive volumes. You can use these switches if you need flexibility in managing downtime, which is incurred when the Chkdsk tool must be applied on large volumes.

In some situations, using the Chkdsk utility with /f switch may lead to hard drive failure. The situations occur if the process is interrupted. After interruption the hard drive integrity is affected and data loss may occur. In order to extract lost data, windows data recovery software are required.

Windows data recovery applications are powerful third-party tools, which work in all cases of data loss. They use extensive scanning techniques to Recover Windows data from failed, corrupted, or damaged hard drive partitions. The software are quite safe and easy to use.

Stellar Phoenix Windows Data Recovery is the most excellent solution for all Windows data loss situations. It is designed for Microsoft Windows 7, Vista, 2003, XP, and 2000. The software recovers lost data from FAT16, FAT32, VFAT, NTFS, and NTFS5 file system partitions.
