Defect Mapping and Spare Sectoring- Recover Hard Drive

In spite of the preciseness manufacturing procedures used for creating the hard drives, this is practically impossible to manufacture a hard drive with millions of sectors and no errors. Imperfections in hard drive media coating and other issues may make the sectors inoperable. An issue with the hard drive sector, if not fixed, generally manifest as error while trying to read data from and write data to hard drive. Such behavior of your hard drive may lead to critical data loss and require Hard Drive Recovery to be sorted out.

Modern hard drives use ECC (Error Correcting Code) to help you identify if errors take place and resolve them. However, ECC can not fix the physical problems and thus prevent parts of the hard drive from being used. Generally such are the individual sectors, which do not work and are known as bad sectors.

The hard drive sectors, which are bad and can not be used for storing the data, because they are not reliable to write data. It is thus required for your system to keep track of which hard drive sectors are bad and not to use them. The most excellent method for it needs to be done for hard drive for detecting and avoiding them. If the bad sectors aren’t detected before they’ve been written, data loss may occur.

At the time of manufacturing, every hard drive is systematically tested for the areas that may have errors to ensure maximum reliability. The process of detecting and removing hard drive bad sectors are known as defect mapping. When bad sectors occur on the drive, you may also feel that your system performance is decreasing.

Bad sectors on the modern hard drive are generally an indication of critical problems with the drive. If a newly purchased hard drive has bad sector, you should get it exchanged. If you see bad sectors on the older hard drives while scanning the drive, you need to get it fixed. The bad sectors result data loss in any form and require Hard Drive Data Recovery to be handled.

Hard Drive Recovery Software can be used to work around logical data loss problems. You can create image of the drive using these applications and perform easy recovery on bad sector affected drives. The Hard Drive Data Recovery applications are completely easy and safe to use with simple graphical user interface and read-only conduct.

Disk Overheating can be cured by Hard Drive Data Recovery

Hard drive overheating is a very common problem with the computers, which are used continuously for several hours. The hard disk’s exhibiting behavior suggests that there might be some overheating issue with the drive, or with entire system. Generally the signs, which suggests overheating are heat that can noticeably felt in the case or the hard drive, or some erratic behavior like system lockups. In such cases, the hard drive may fail physically and lead to critical data loss situations. At this point, hard drive recovery methods are required to extract data from failed hard drive.

Hard drive overheating is one among the major enemies of the reliable computer system. A system, which runs over the general temperature will have short life span as compared to a computer with effective cooling system. There are strong chances that the computer will be unstable. The overheating damages internal components of the hard drive and lead to severe hard drive failure.

To keep an eye on the hard drive temperature and other factors, you should keep the hard drive S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) feature enabled. This is a monitoring mechanism for hard drives to find and report on different reliability indicators. It has threshold values for all hard drive factors and alerts you when these values are exceed.

You need to be careful while checking the hard drive or other computer parts for the heat level. Check the temperature of the hard drive using S.M.A.R.T. feature. If it is more than general temperature, turn off your system immediately and perform following checks-

1. Check the hard drive fan and ensure that it working. It is a primary cooling system of hard drive.

2. Check internal fan of your system. The fan is placed over the processor.

3. Place your system in cool area. Improve ventilation in the hard drive case, if it is not adequate.

In case if the overheating cause damage to hard drive components, data loss situations may occur and you need Hard Drive Data Recovery to handle the situations.

Hard drive recovery in such circumstances is possible with the help of Hard Drive Data Recovery service. It is a personalized and sophisticated help, delivered by recovery experts through safe and sterile environment of Clean Rooms. The use cutting-edge technologies to ensure absolute and safe recovery in all possible data loss scenarios.

What Are The Causes of Setup Errors During Windows XP Upgrade?

Microsoft Windows XP is perhaps the most widely used version of Microsoft Windows. It has set various technology benchmarks in terms of data storage and data security. So users having older versions of Windows like to upgrade to Microsoft Windows XP. In order to upgrade to MS Windows XP, you are required to have installation CD of Windows XP that gives setup wizard for completing the operation. But in some cases, the upgrade process gets halted and earlier version of Windows become unusable. Such situations make your hard drive data inaccessible and lead to data loss. At this point, you need to perform Hard Drive Recovery to get your data back.

For instance, you may come across some error message while upgrading to Microsoft Windows XP and the installation process can not proceed. The error messages may sound like the followings:

“Setup is unable to perform the requested operation on the selected partition. This partition contains temporary Setup files that are required to complete the installation.”

Furthermore, your system might stop responding with the below error message:

“An error has been encountered that prevents setup from continuing. One of the components that windows needs to continue setup could not be installed. Data error ‘cyclic redundancy check’”

In addition to the setup process, the error messages also indicates that there is some problem with hard disk. The problem could be damaged metadata structure, virus infection, and Raw file system. Errors occur as setup attempts to fix the hard drive issues. In order to access data from the hard drive, you need find out the cause of this problem and fix it through hard drive recovery.

Cause

The problem occurs because the hard drive is having logical damage. Setup can not properly write data to the damaged disk and thus gives the errors. In these cases, previously stored data also become inaccessible.

Resolution

use chkdsk /r utility to fix this problem or let the setup to sort it out. If both of the methods fail, go for hard drive recovery software to ensure complete and automated recovery of all your lost data.

The Hard Drive Data Recovery applications are quite easy to use with simple user interface. They use high-end scanning techniques to thoroughly scan the hard drive and extract lost, missing, and inaccessible data from it. The programs keep integrity of your data as they have read-only conduct.

Hard Drive Recovery to handle Inaccessible Boot Device

It may happen that all of sudden your system refuse to boot without any strange sounds such as clicking and tickling. Here you cannot access your data and face a critical data loss. In such situations Hard Drive Recovery comes as a cure.

Well, this could be due to both mechanical and virus problem as well . Unfortunately the operating system does not include any utility to prevent boot sector virus. Thus you are required to go for third party anti virus software to avoid such issues from being occurred.
There may be one more reason for this behavior and that is problems in OS registry .

In particular, when the device drive that is associated with the drive controller is damaged, the hard drive could become inaccessible. Such problems prevent your computer hard drive from being accessed and booting normally. To resolve this problem we require hard drive recovery.

Some users might consider it the case of operating system malfunction and they reinstall the operating system after formatting the hard drive. Some may also use the System Recovery Disk to resolve such issues. But These procedures might overwrite the stored data and might cause permanent data loss so, try to avoid these behaviors .

If a user has already done this mistake and facing a severe data loss problem , then a third party data recovery software is recommended to recover hard drive data.

How Overheating Can Damage Your Computer Hard Drive?

The hard drive, most popular and widely used data storage media, is extremely prone to failure. Major reasons of hard drive failure are overheating, mechanical failure and electrical failure. The internal components of hard drive are pretty fragile and may fail if the temperature of hard drive gets increased up to an extent, which the drive can not resist. Other causes of drive failure includes file system corruption, operating system malfunction, virus infection and so forth. Crash or failure of hard drive usually cause in serious data loss situations and requirehard drive recoveryto be sorted out.

Hard drive failure renders all of your critical data on the hard drive inaccessible. The overheating expands the hard drive platters and they touches read/write head. It causes head crash, which is the most common cause of mechanical failure and data loss. The failed hard drive needs Hard Drive Data Recovery to extract lost data from it.

Every computer hard drive has a upper and lower operating temperature limit that works as threshold values for the drive. When the hard drive temperature exceeds the upper limit, the drive catches high risks of failure and losses its life if you continuously operate it above maximum temperature limit.

Although, you have computer fans installed in your system to prevent overheat and damage to the system due to overheating. If the failure occurs, you need to Recover Hard Drive and retrieve data from it.

You should never attempt any recovery on your own on the physically damaged hard drive. It might cause further damage to the hard drive and make your data irretrievable. If you open the damaged drive in general environment, sensitive platters of hard drive could get damaged due to dust particles available in environment.

In such situation, personalized and sophisticated recovery helps is required, which is known as Hard Drive Recovery service. It is carried out in safe and sterile environment of Clean Rooms using advanced tools and techniques. The recovery professionals have enough skills and experiences of handing all types of data loss situations effectively. Experts first completely analyze the hard drive and then find out the exact cause of the problem. To avoid further damage to the hard drive, they never attempt any recovery procedure on the original drive. They create image of the drive and apply hard drive recovery software solutions on the same.

Stellar Information Systems Limited is the foremost provider of high-quality recovery service. The service is available for all hard drives that have IDE, EIDE, SATA and SCSI interfaces. Drive is opened and operated in controlled surroundings of Class 100 Clean Rooms.

EFI Bootloader Error and Recovery

For EFI-based computer systems, the boot loader is IA64ldr and performs the same functions as NTLDR does in x86 or x64 systems. Each operating system on such systems maintains its individual copy of boot loader on EFI partition. Windows component- Ia64ldr.efi loads Hal.dll, system boot drivers, Ntoskrn.exe files to successfully start the boot the process. But, if the file gets corrupted or goes missing somehow, a Windows-based computer loses the ability to boot, while rendering your stored files and folders inaccessible. You can deduce such issues from error messages that display when you try to start the computer. However, to solve these problems, you should try replacing the damaged or missing boot loader file using boot disc. If this fails, use your backup to restore data or opt for a powerful hard drive recovery utility.

For example, you might receive the below error message when trying to start a EFI-based computer systems installed with Windows operating system:

“Couldn’t find loader.

Please insert another disk.”

Such errors imply that your stored files and folders are inaccessible and you cannot boot into the computer.

Cause

Ia64ldr.efi file is either missing or damaged. This file is typically located at \Device\HarddiskVolume1
\EFI\Microsoft\WINNT50\ .

The error might also occur if computer is trying to boot from a non-bootable media.

Solution

Make sure that no external media is inserted when you are trying to start the system. To boot the computer and resolve the issue, you should follow these steps:

  • Insert the Windows installation or boot disc and boot your computer from it. To accomplish it, you need to edit the BIOS settings to boot from CD-ROM and restart the computer.
  • Press any key when prompted for
  • Replace the corrupted or missing boot loader and NTDETECT.COM file
  • If this works, you will be enable to access data. But if it fails, you are suggested to restore data from backup or employ a hard drive recovery software that could access and recover those lost files.

    Hard drive recovery utilities are high-end applications, specially designed to scan and recover data while maintaining its integrity. They can be easily implemented because of graphically rich user interface.

    Stellar Phoenix Windows Data Recovery is a professional and completely reliable data recovery tool with advanced options and features. It is a safe hard drive recovery softwarethat supports Windows 7 RC1, Vista, XP, 2003 and 2000 based systems. The tool provides you features like Append Header, RAW File Recovery, Save Scan and more.

    SAM Corruption in Windows XP

    Windows XP SAM (Security Accounts Manager) is a database registry file storing user’s passwords and uses hash format. A Windows XP installed computer might fail to start if the file goes missing or damaged. For solving such problems, use the file backup provided you have backed up the system state or try to copy it using parallel installation. However, if none of the measures works, perform clean Windows XP installation and restore data from backup. In case of valid backup unavailability, a hard drive recovery software can help extracting all your lost files and folders.

    For instance, a Windows XP Home or Professional Edition installed computer might prompt the following error when you try to start it:

    “Security Accounts Manager initialization failed because of the following error: A device attached to the system is not functioning.
    Error Status: 0xc0000001.
    Please click OK to shut down this system and reboot into Safe Mode, check event log for more detailed information.

    Starting the computer in Windows Safe Mode doesn’t help and prevents you from accessing the stored files.

    Cause

    Windows XP SAM file is either missing or damaged.

    Solution

    You cannot use any Recovery Console method as it requires authentication that SAM provides.

    Following are the recommended solutions to the given problem:

    • If you have backed up system state using Windows Backup utility, use it to restore SAM through Automated System Recovery Wizard or Restore Wizard
    • Perform parallel Windows installation and execute the following set of commands using command prompt:
    • copy c:\windows\system32\config\sam c:\windows\tmp\sam.bak
      delete c:\windows\system32\config\sam
      copy c:\windows\repair\sam c:\windows\system32\config\sam
    • Replace the SAM file by reinstalling Windows XP. Restore data from backup

    At times, backup cannot restore desired set of files. To deal with such situations, windows hard drive recovery utilities are available to prevent rework. Hard drive recovery software are graphically rich applications with suitable recovery features to provide safe, comprehensive and robust data recovery. These tools are specially designed to scan a logically crashed drive to locate missing data.
