Stellar Phoenix Windows Data Recovery

A User32.dll file in Windows XP operating system is an important file that stores information related to graphic elements. The file is used at the time of booting of Windows and if corrupted, does not allow the system to boot. Few main causes for User32.dll file corruption are damaged program files, device driver issues, virus infection, registry damage, improper memory allocation, and human errors. In most of User32.dll file damage cases, you encounter a STOP error message that appears at the time of booting of Windows XP operating system. This error message makes Windows based-hard drive data inaccessible. The problem can be easily surmounted by restoring the data from an updated backup. But, if you do not have any backup file, then you need to use advanced Hard Drive Recovery Software.

The above scenario can be explained with the below error message:

“STOP: 0xc0000221. Bad image check sum, the image user32.dll is possibly corrupt. The header check sum does not match the computed check sum.”

This error message occurs when User32.dll gets damaged. The user is neither able to view the previously saved data nor store new data post the occurrence of the above error message.

Resolution:

The resolution for the above error message is replacement of corrupt User32.dll file:

1.Reboot your computer after inserting the Windows XP CD-ROM.

2.To start the Recovery Console, press ‘R’ on the ‘Welcome to Setup’ screen.

3.In case of multi-boot, choose the required Windows XP installation.

4.Type the administrative password in case you are prompted to do so. Press Enter.

5.Type the below command at the command prompt and then press Enter:

cd windows\system32

6.Next, type the below command to rename the User32.dll file and press Enter:

ren user32.dll user32.bak

7.The new copy of the User32.dll needs to copied in System32 folder. To do so, you need to type:

expand cd-rom:\i386\user32.dl_ c:\windows\system32

8.Restart your system after exiting from the command prompt.

In most cases, the error message does not pop up after you restart your system. However, if it does, then you need to format your system. While formatting allows you to restart your system and store new data, it also deletes the previously saved data from your hard drive. To recover that deleted data, you need to use an effective Hard Drive Recovery Software. Such Hard Drive Recovery solutions can be downloaded directly from the Internet.

The structure, which gives FAT (File Allocation Table) file system its name is File Allocation Table. For understanding what this significant table does, you need to first understand how much space on hard drive allocated in the system that uses FAT file system. The data is actually stored in soul sectors of 512-byte in size. This is possible for every file to allocate the individual sectors. But in some situations, you may not access your critical data from the Windows hard drive due to file system errors and come across data loss situations. In such circumstances, you need to use Hard Drive Recovery solutions to extract lost data from affected drive.

However, for the performance reasons, soul sectors aren’t allocated to the files in FAT file system. It takes a huge amount of overhead for keeping track of the pieces of the files that are very small in size. To overcome this problem, the hard drive is divided into the larger pieces, known as clusters or allocation units. Every cluster has various sectors. Generally, the cluster range from 2,048 to 32,768 bytes in size that represents 4 to 64 sector each.

File allocation table is the data structure that stores information about the clusters. Every cluster has entry in FAT, which describes how this is used. It tells operating system about availability of the hard drive parts and detail of the allocated parts. File allocation table is stored in hard drive area, just after VBR (Volume Boot Record). Every volume contains two copies of FAT; ostensibly, second copy is a backup and used in case of any damage.

Damage to FAT can lead to data loss because it is where all the records are stored of which part of hard drive has which files. The second copy of the FAT is used when primary copy gets damaged.

In FAT system, though, backup FAT system may not work well. The issue is that the second copy is stored next to first one. If bad sectors affect the first copy of FAT, there are strong chances that the second one is also affected. In such situations, hard drive data recovery solutions are required to extract lost data.

Hard Drive Recovery Software helps you in such cases to get your valuable data back. The applications use powerful scanning techniques to ensure quick and absolute Hard Drive Recovery in all data loss circumstances.

Stellar Phoenix Windows Data Recovery is an advanced application for assured recovery of lost data. The software is designed for Windows 7, Vista, 2003, XP, and 2000. It recovers data from FAT16, FAT32, VFAT, NTFS, and NTFS5 file system partitions.

Microsoft Windows uses a number of DLL (Dynamic Link Library) files to complete its operations. In order to call methods from the DLL files, rundll is used. It is a Windows system process that should not be terminated for properly working of the system. But in some situations, when you boot your system, the process does not complete and you get some error messages stating rundll file is missing. This behavior of Windows renders your system unbootable and prevent you to access data from your hard drive. In such situations, you need Hard Drive Data Recovery to retrieve data from your affected Windows computer.

In a practical scenario, when you boot your Windows computer, you might come across rundll error messages, similar to the following ones:

“Windows cannot find C:\Windows\Rundll32.exe make sure you typed the name correctly and try again.”

“Can’t Find rundll.exe file.”

“Rundll file missing.”

“Error loading C:\WINDOWS\SYSTEM\ctrlpan.dll. The system cannot file the file specified.”

Rundll errors commonly occurs during Microsoft Windows startup and shut down processes. They are not just the annoying issues, which appears on Windows screen; rather, the could affect stability of your Windows system and cause serious data loss. In such cases, Hard Drive Recovery is required to sort out the problem.

Root of the issue

You might encounter this problem due to corrupt or missing rundll files. The rundll files may corrupt due to virus infection, improper system shutdown, operating system malfunction and other similar reasons. Such issues may also occur due to corruption to Windows registry. Registry corruptions needs to be handled with care as improper editing of Windows registry might lead to critical situations.

Resolution

In order to sort out this behavior of Microsoft Windows, you need to format the hard drive and reinstall Microsoft Windows. This behavior replaces all damaged rundll files and fix this issue. But it also remove all of the data from your hard drive and need Hard Drive Recovery to be sorted out.

Recovery is best possible using effective and advanced third-party Hard Drive Recovery Software. The applications are capable of methodically scanning affected Windows hard drive and extract all of the lost data from it. The tools are quite safe and easy to use with read-only conduct and rich graphical user interface.

Computer viruses are the self-replicating programs that can infect your computer system without your permission. Virus infection is one of the major reasons that cause data loss. These can be transmitted as a downloadable file or e-mail attachment or can be present on a CD or a diskette. To prevent against virus infection, Hard Drive Recovery experts always suggest installing a quality antivirus plus keep it up-to-date. An antivirus or security suite can detect and quarantine or remove harmful applications as worms, viruses, trojan horses etc. You should also use efficient antispyware and antispam software for complete PC protection.

Consider a practical instance, you turn on your Windows system and the boot process fails with the following error message:

“STOP Error 0×0000008B
MBR_CHECKSUM_MISMATCH”

The error further describes four parameters: disk signature from MBR, MBR checksum calculated by operating system loader, MBR checksum that is calculated by system and reserved. After this error message, you can’t access your critical data.

Cause

The error message occurs due to MBR (Master Boot Record) checksum mismatch. When the MBR checksum calculated by the system doesn’t match with that of passed in by the loader, the system fails to boot with above STOP error. It happens when the hard disk is infected from virus.

Solution

In order to resolve the above issue, you need to follow these steps in order:

• Scan your hard disk with powerful and up-to-date antivirus software. To perform this, you need to boot your system using a write-protected disk that contains the virus scanner. These applications can help to disinfect the system.
• If your antivirus can’t fix hard disk infection, you need to reformat the hard disk and restore lost files and folders using recent data backup.

In case, data backup is unavailable or it fails to restore the required information, you can use Hard Drive Recovery Software.
Hard drive recovery applications are special tools that can recover and restore lost data in cases of logical hard disk crashes as file system corruption, operating system damage etc. With completely safe recovery process, these tools can recover all types of lost files and folders, including system and data files. Also, they provide several advanced recovery options. Such software are designed with graphically rich interface and hence you can use them quite easily.

Stellar Phoenix Windows Data Recovery is the foremost hard drive recovery software to recover the lost data including deleted e-mails. The software can recover data from corrupted, deleted, lost or formatted partitions and volumes. It supports FAT16, FAT32, VFAT, NTFS and NTFS5 file systems. The software is compatible with Windows Vista, XP, 2003 and 2000.

Computers with EFI (Extensible Firmware Interface) use GPT (GUID Partition Table) as the standard hard disk partitioning system. Intel proposes EFI as the replacement for the PC BIOS that uses Master Boot Record (MBR).In GPT partitioned disks, data that is important to platform operation is placed in partitions and not in hidden or unpartitioned sectors as done in MBR partitioned disks. Due to this reason, you encounter issues while installing Windows operating system. To solve such issues, you might need to recreate all hard disk partitions and opt for suitable partitioning scheme. Recreating the partition structure erases all data and you need to use an updated plus valid data backup to restore the lost data. However, if data backup is not updated, is corrupt or absent, you need to use hard drive recovery applications to extract the lost or inaccessible data.

As a practical instance, when you attempt to install Windows Server 2003, Windows Server 2003 64-Bit version or Windows XP, you might receive the below error message:

“Setup cannot install to the selected partition.
You can only install to GPT disks on IA-64 machines and MBR disks on X-86 machines.
You can only upgrade installations on GPT disks on IA-64 machines and MBR disks on X-86 machines.
To go back to the previous screen press ENTER”

Cause

This error message occurs if both these conditions are true:

1. An operating system is already installed on the hard drive or it had an operating system, which has now been removed.
2. Hard drive is using GPT

You fail to install the required operating systems on GPT hard drives because of the following reasons:

1 On GPT hard drives, you can only set up Windows Server 2003 for Itanium-based systems.
2 You can’t set up Windows x64 based and Windows 32-bit operating systems on GPT hard drives.

Solution

You need to convert your GPT hard drive to a MBR hard drive. You can use Disk Management snap-in or diskpart command for it, if an operating system is already installed. You can also delete all existing hard drive partitions using Windows Setup and opting for the option to convert the partitioning scheme. In Windows Server 2003-based systems, it must have Windows Server 2003 Service Pack 1 installed. After this, you can restore lost data from backup. If the backup is invalid (viz. causes one or more errors during restoration) or incomplete, you should use Hard Drive Recovery tools to recover your critical data.

In case your computer is not able to boot, the hard drive crash can not be the only reason behind it. You should try to reboot the system in a different mode viz. Safe Mode, check all cables and connections. If this doesn’t help, then you need to shut down the system and consult Hard Disk Recovery service professionals.

If system can boot from the hard drive till it can display error reports through video subsystem, it becomes easier for a user to diagnose the actual problem. One of such error messages is:

“Initialization error on HDD0”

Where, HDD0 shows that main hard drive has got failed. Based on number of hard drives attached and their configuration, hard drive number may vary.

The error message occurs when computer system encounters issues starting from the hard drive after POST (Power On Self Test). It occurs due to physical issues with one or more hard disk components (mechanical or electronic).

Reason

A hard drive may get failed due to number of reasons:

• Head Crash: This is a frequently occurring instance. It occurs when read/write head comes in contact with the fast moving platters. It is the prime cause of physical damage to their magnetic material. Data lost post such malfunction is not recoverable.
• Air Filter Crash: Hard disk incorporates an air filter to maintain air pressure levels and moisture. However, when air filter function gets affected due to faults, dust particles may settle down on platter surface and create obstacles in read/write operations. More severely, it may cause head crash.
• Other Components Failure: Other hard disk internals may also fail. This includes spindle motor, spindle, actuator, head arms etc.
• Electronic Failure: A hard disk is comprised of several Integrated Circuits (ICs) that control its internal functioning. Their damage can make hard disk inaccessible.
• External Factors: If hard disk is exposed to high intensity magnetic waves, heat, water, shocks, heat or power surges, it may stop functioning.
• Wear and Tear: The continuous use of hard drives for long time intervals can cause wear and tear to its parts and make them fail. Hard drive manufacturers provide the expected time of failure known as MTBF (Mean Time Between Failures) on their manuals, which is estimated by considering that hard disk is used under normal conditions.

Hard Disk Recovery service helps users to reclaim their lost data from such physically failed hard drives. To determine the cause of failure, affected hard disks are opened under safe environment of Clean Rooms. Clean Rooms are controlled lab environments to perform intensive component level tasks. After the cause of crash is known, hard drives are treated with appropriate Hard Drive Recovery procedures, which are tailor-made solutions as per nature of the problem.

Stellar Information Systems Limited is the premier provider of state-of-the-art hard drive recovery services. The data recovery service is provided in Class-100 Clean Rooms. Our recovery solutions are available for almost all types of hard drives as SCSI, SATA, EIDE and IDE. We also provides solutions for Server, RAID, NAS and SAN hard drives.

Microsoft Windows XP is based upon the architecture of Windows 2000 and NT. But sometimes, during Windows XP installation, you may face issues like system file corruption. In such cases, you should take data backup as the solution may require a clean Windows reinstall. In case of backup unavailability or other issues like error occurrence while restoration, hard disk recovery becomes necessary to retrieve lost data.

As a practical scenario, you may encounter the following error during Windows XP bootup:

“The file C:\windows\system32\c_1252.nls is missing or corrupt”

The error message occurs due to the corruption or loss of ‘c_1252.nls’ file.

• NLS stands for National Language Support. The files with .nls extensions are code page that consist of tables. They are used to translate text into other languages or alphabets.

Solution

The possible solutions are:

•You can use Windows XP operating system disk to start the system and select recovery console option. You need to use the chkdsk/r command in recovery console. This command is used for repairing hard disk errors.
•If the problem persists, you can replace the required system file (c_1252.nls). It can be accomplished through Recovery Console with these commands:

cd system32
ren c_1252.nls c_1252.old
expand Drive Letter:\i386\c_1252.nl_ c:\windows\system32

Here, drive letter: can be C:, D: as per the system.
• If hard disk is formatted with FAT32 file system, you can replace the file by using Windows 98 emergency boot disk. After starting the system using this CD, the following commands need to be typed at the command prompt:

c:
cd windows\system32
ren c_1252.nls c_1252.old
extract drive:\i386\c_1252.nl_

This method is useful when Windows XP Recovery Console is not able to solve the problem.

•You can also try upgrading Windows XP

•If this doesn’t resolve the system behavior, you can go for clean Windows XP reinstall after backing up all important data. Backup must be checked as incomplete backup may lead to hard drive recovery post data loss.

Hard disk recovery is possible using commercial data recovery tools. These hard drive recovery software can scan the drive and recover data. The applications can be used in each logical data loss situation. They offer interactive interface and advanced options to achieve precise data recovery.
