Consider the case of Mike. His computer was one of the computers that got burnt. All the plastic components and the electrical parts were either burnt, charred or just melted. And whatever was left faced the wrath of fire fighting tools, i.e. water and sand. Needless to say, they caused more harm to the system. And to make matters even more worse, the debris and smoke damaged the leftover parts as well. Though all parts can be replaced, if only the platter inside the hard disk has not been damaged. The entire system can then be built around that platter. Or the data saved on the platter, can be transferred to another storage device.

But the good part is, despite all the problems, hard drive recovery experts can recover all that data for you. Though a repair shop might be able to fix the thing for you, but the work and the system is not stable. This makes the data availability difficult. In worse cases, the platter may be damaged even while it is being read. That is why, one should rely on recovery of data, instead of depending on making the system functional again.

Data Recovery services are provided by many companies today. But choose your company wisely and carefully. Delay is better than losing data completely. A company with good experience in the field with good number of techniques, and tools, coupled with sterilized clean rooms is the best bet.

Stellar Information Systems Ltd. is an old hand in extending data recovery with more than 17 years in this field. With an ability to recover data from any kind of storage media, the company has Class 100 clean rooms, proprietary tools and techniques, and boasts of more than 1.1-million customers worldwide.

The complication results in system failure and thereby data loss or inaccessibility. Under such circumstances, the best possible way to recover back your data from the hard drive is to run any hard drive recovery software.

Suppose, you are using a Microsoft Window Vista operating system based computer, which has a SATA hard disk with full hard disk encryption facility and you use PATA mode, then the system behaves abnormally and stops responding. Sometimes, the system crashes causing some file system corruption leading to data loss and inaccessibility.

Resolution:
The best possible way to start resolving an issue is to correctly find out the cause behind the problem. Here, as you sense a possible corruption to the file system, you must run ScanDisk to try repairing the corruption and check the health of the hard disk.

If the hard disk is accessible, then, below steps will guide you through the process of running ScanDisk from within the Windows:

•    Go to START, then PROGRAMS, then ACCESSORIES. After that point to SYSTEM  TOOLS and within that click on ScanDisk.
•    Choose the disk or drive on which you want to perform the test.
•    Select the option THROUGH and then run the ScanDisk.

Following steps will guide you to run the ScanDisk from the command prompt, in case the system is not accessible:
•    Start the system in DOS mode.
•    Press ENTER after typing the following command:

scandisk <X>

Note: <x> meants the letter of the hard disk you are checking.
•    Once, the ScanDisk finishes the initial check, it prompts for a surface scan on the drive. Allow it by clicking on YES or press ENTER.
If the above processes fail to fix the errors, then your data remains inaccessible and you have to restore the same from your backup server. In case, you have not taken backup or backup also fails to restore your valuable data, then only any hard drive recovery software can recover your data back.

Stellar Phoenix Windows Data Recovery is a well known windows hard drive recovery application that can recover your lost, deleted, formatted and inaccessible data from the FAT and NTFS based volumes. This utility recovers almost anything including files, documents, pictures, audio, video, animated files etc and supports more than 185 file types. This utility also features hard disk cloning, imaging and works well with Microsoft Windows 7, Vista, XP, 2000 and 2003.

Still, there are several third-party tools available in the market to safely modify the existing cluster size. But, it is always advisable to take backup of your important data prior to the usage of such utilities as the process may cause serious corruption to the file system and data loss or inaccessibility. However, if you still witness any instance of data loss, you can use hard drive recovery software to recover back your valuable data.

In order to describe the above situation, let us suppose that you used a third-party software to modify your hard drive cluster size. The process got completed lucidly until the next time, you tried to boot the system. The next time, when you boot your system, the booting process halted in the middle and you tend to receive  an error message. Thereafter, all your data stored in the hard drive became inaccessible. The error message can be read as below:

“A Disk read error occurred. Press Ctrl-Alt-Del to restart”

Cause:

The above error message appears because of a possible corruption to the Master Boot Record or MBR.
Note: MBR is the boot sector or the first sector of a partitioned storage media. Moreover, MBR is responsible for recognizing the partitions and loading of the operating system.

Resolution:

In order to resolve the above error, you need to boot your system with the Windows installation CD or DVD. Thereafter, at the command prompt, run the command ‘fixmbr to repair the MBR.

However, if ‘fixmbr’ command fails to repair the MBR, you have to reformat the hard disk and make a fresh installation of the operating system. Formatting erases the whole data from the hard drive and you have to restore the data from the backup. In case, backup is not available or failed to restore back the data, only any Windows hard drive recovery software can help you recover your data.

Stellar Phoenix Windows Data Recovery is a highly appreciated utility to recover hard drive data irrespective of the data loss situations. The software is compatible with Windows 7, XP, Vista, 2000, 2003 and is capable of recovering any deleted, lost, formatted or inaccessible data from FAT and NTFS file system based drives.

Consider, that you install a device driver and update your Windows 7 OS. After successful installation of the same, when you restart your system, you face the dreadful blue screen with the following error message flashing on it:

‘STOP: 0×0000006B (Parameter1, Parameter2, Parameter3, Parameter4) PROCESS1_INITIALIZATION_FAILED’

Upset by this, you restart the computer, to get rid of the error, but again find the same problem. Irrespective of the number of boot attempts, you always face the same problem. Owing to this, all the data saved in your hard drive cannot be accessed, and you are at the verge of its loss.

The error is flashed due to a system conflict caused by installation of the device driver, a hardware device, its driver, or some related software. Blue screen error and stop code are clear indication that Windows has has shut down the computer abruptly to protect itself from data loss.

To work around this problem, you need to isolate the problem and to access hard drive. For this, follow the below mentioned steps,

• Run virus scan on your computer
• Run Chkdsk/r on the primary disk and also the Utility Drive hardware diagnostics to scan your hard disk
• Also run Windows Memory Diagnostic test in System Recovery Option
• If no errors are found, try to go for System Restore
• If that doesn’t work, you may opt for Startup Repair
• But if even these don’t help, then reinstall your Windows OS. Needless to say, a lot of data would be lost. But with comprehensive backups, it may not be difficult to perform hard drive data recovery, unless you opt for a specialized software to perform hard drive recovery.

Stellar Phoenix Windows Data Recovery is a highly specialized software for all your recovery needs. With an ability to recover data from FAT, NTFS and exFAT systems, this tool supports more than 185 file formats. This hard drive data recovery software is compatible with Windows 7, Vista, 2003, XP and 2000, and is available with a Boot CD on demand.

The command can be used to make an exact image of the data from the dying hard drive and can be restored later on. However, under unfortunate incidents, the disk image refused to be mounted and it seems as if all your data is lost. These are the extreme conditions, where you have to think over technologies like Mac hard drive recovery or Mac recovery software.

Facts about ‘dd’ command:

This is a common piece of UNIX command with the purpose of copying and converting raw data. ‘dd’ is usually used to copy a specified number of bytes or blocks of data and similarly byte level conversion, such as EBCDIC to ASCII conversion. Though this command is used to backup the boot sector of a hard disk, still you can also use it to copy the entire partition or disk. ‘dd’ command copies the information about deleted and formatted data as it copies byte by byte, whereas the usual ‘cp’ command misses it. Moreover, this command can make a copy of the specified data irrespective of the data type or the file system.

The Problem: your data in the Mac OS X based volume is inaccessible and you have sensed some problem with your hard drive. You accessed your drive through your UNIX OS and made an image of your data by using the ‘dd’ command. Later, when you try to mount the image and restore the data on your Mac OS X, it showed an error message and stuck. The error message read as:

“No mountable file systems”

As the data image is refused to be mounted, you cannot restore the your data, through the image, you had made by the ‘dd’ command.

Cause of the problem: The most likely reason is that the data image made by the command is corrupted.

Now, if you have taken backup of your data, then you can restore the same from the updated backup. In the absence of a valid backup, try using Mac recovery software.

The Mac recovery software are developed with advanced techniques to recover all your deleted, corrupted or inaccessible data from a troubled hard drive. You can easily use these software without any prior knowledge as they come with detailed instructions for each step.

These huge number of hard drives have one thing in common, they store a huge amount of data, including digital data in a relatively simple manner. They are the heart and soul of the computer, and enable it to the efficient machine that a computer has become today. That is why they need to be safeguarded, otherwise, a user has to opt for hard drive recovery methods.

A hard drive is the storage area of the system and stores all programs and applications. It may have any interface, or any operating system, but nothing can prevent data loss from it when a problem comes.

These problems include, but are not limited to, corruption of file system, cross linking of files, improper shut down of the system, corruption of the master boot sector, and corruption of boot sector. In such situations the only thing that can save the work of a user is a valid and updated backup.

A backup can be taken on any device, including, tapes, USB drives, external devices, or even in the same hard drive. It is also possible to keep a backup online. A backup can be used to recover hard drive data, irrespective of the reason of data loss. But for all those who have either not maintained a backup, or have a backup, which is not valid or updated, there is still some help available.

With the advancement of technology, it has become possible to perform hard drive recovery after data loss owing to the above mentioned reasons. It is also possible to recover data that has been lost due to different reasons, including, files lost due to emptying of recycle bin or due to pressing of the ‘Delete’ button while ‘Shift’ key was pressed, data lost due to formatting or resizing of a particular drive, or due to formatting of the whole disk. There are reliable third party hard drive recovery software that are available in the market today.

Stellar Information Systems Ltd. is a pioneer in making simple, read-only, and intuitive hard drive recovery software for Windows, Novell, Mac, Linux, and Unix operating systems. With interactive graphical user interface, and a detailed user documentation, these tools are very user friendly and feature a number of options to recover hard drive data.

Scenario:

You are trying to read a particular file and the system halted with an error message leaving you to  search over any mac recovery options. The error message reads as bellow:

Error:

“-36 error (I/O Errors (bummers) ”

Probable cause:

The reason behind the above error is that the particular file is finding difficulty in either reading from the drive or writing to the drive. This is due to the fact that the file
may have been improperly written to the drive or chances are there, that the disk may be damaged. In most of the cases, the above said error indicates towards a media error or error with the hard drive.

Resolution:

Try to reboot the drive with all extensions off. Once in a while, rebooting allows you to read the data, as sometimes, the error is transient, however, this is rare.

OR

If the drive is accessible, then try copying/moving the troubled file to another disk, as it may resolve the issue.

If both the measures fail, try any mac hard drive recovery software, that only can get back your lost or inaccessible data.

These mac recovery software are capable of retrieving your lost, missing or inaccessible data from any formatted or inaccessible Mac hard drive. These commercial mac hard drive recovery utilities are designed with interactive user interface and have instructions for every step you are to make, leaving your mind absolutely stress free.

However, there are some workarounds to deal with this problem. If these do not work, then I would recommend to use a third-party Windows hard drive recovery software to recover hard drive.

Taking a real-world example, consider that you are trying to start your Windows XP system but fail at the booting stage. An error message is displayed, that is:

“Windows could not start because of a computer disk hardware configuration problem.

Could not read from the selected boot disk. Check boot path and disk hardware.

Please check the Windows documentation about hardware disk configuration and your hardware reference manuals for additional information.”

Cause:
This booting problem can happen because of the following reasons:
The Ntoskrnl.exe file is damaged, corrupt, or missing.
There is hardware problems with the system.

In the Boot.ini file, the path of the partition is not set correctly.
Windows XP is installed at a location that is not specified in the Boot.ini file.
The boot loader section in the Boot.ini file contains invalid Default value.

Resolution:
To resolve such problems, you should perform either of the following methods to recover hard drive:
Edit the Boot.ini file: You should edit the Boot.ini file to rectify the Default value. Also, you should make sure that the all the respective entries in the [Operating System] section refer to the Boot.ini file.
Use the Bootcfg utility: You should rebuild the Boot.ini file in the Recovery Console using the Bootcfg.exe tool.
Run the CHKDSK command: You should use the chkdsk command to scan and repair any hard disk-related issues. For this, you should use the chkdsk command with the following syntax:
CHKDSK /r

These mentioned methods are sufficient enough to repair such issues. Having said that, there are times when you cannot boot the system even after using these methods. There are certain third-party hard drive recovery software that can help you to recover hard drive in such situations. These Windows hard drive recovery tools have highly interactive user interface that make the data recovery easy and safe.
