Data Recovery Software Help For Windows, Mac , Linux Systems

All file systems (including of Windows, like FAT32, NTFS etc.) use a definite cluster size to organize data on the hard disk. The hard disk cluster size is the smallest value of disk space that is allocated to hold a file and is defined at the time of formatting the disk. When you try to change the set cluster size value of hard disk, chances are that the process may affect the boot structures as well. The third-party utilities that claim to safely change the cluster size value can sometimes, bring adverse effects to the Windows boot process. Thus, it is strongly recommended to backup all your data prior to use any utility that draws any direct consequences to your hard disk structures and data. But if you still lose data, you can use a Partition recovery utility to perform data recovery. Partition Recovery

To elaborate such problems, suppose you use a third-party software to change the existing cluster size of your Windows based hard disk. The utility reports successful process completion. But the next time, when you try to boot the computer, it fails and you receive an error message, similar to below:

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

The data stored on hard disk is inaccessible and you cannot boot the computer even at subsequent attempts.

Cause

The described issue can occur due to corruption in hard disk MBR (Master Boot Record). MBR is the first sector read by computer to load the operating system and find disk partitions. The third-party software used in this case can corrupt the MBR.

Solution

Boot your computer using Windows installation disc and start command prompt. To fix and rewrite the MBR, you need to run the /fixmbr command.

If this solution doesn’t work and data is still out of access, you are suggested to use a Partition Recovery Software to recover the lost data, however, you can reformat the disk if a good backup is available. Partition Recovery utilities use effective scanning algorithms to analyze the crashed disk and extract the lost data safely.

Stellar Phoenix Windows Data Recovery is a fully-featured data recovery utility designed for Windows 7, Vista, XP, 2003, and 2000 based systems. The advanced Partition Recovery Software is compatible with FAT32, VFAT, NTFS, and NTFS5 file systems. The software has a graphically enriched interface with powerful features, like RAW File Recovery, Disk Cloning, Disk Imaging etc.

When your system boots up, BIOS (Basic Input/Output System) setup performs POST (Power On Self Test) for checking the system and ensuring that everything is functioning properly. If BIOS is able to start your system and gain access to video subsystem, it displays information about system as it starts up. However, sometimes you may come across boot error messages, which prevent your system from booting. It renders all your critical data inaccessible and leads to data loss situations. At this point, you need to perform data recovery through appropriate solutions.

The error may be caused by several different components of your computer, depending upon how far into boot process the operating system gets before the error is produced. Majority of the errors are caused by your system BIOS because it handles most of the system booting functions. Other error messages can be the operating system specific.

There are several individual error messages and some are very common as there are a few different BIOS manufacturers, which are used by most of the systems today. But, since the actual wording of error may be changed by manufacturer of every motherboard or system, there are many variations. One common example of boot time error message is as follows:

“Disk Drive failure”

After above error message, your system can not boot up and you can not log into the system. All your data business-critical becomes inaccessible. In order to gain access of your significant data in such cases, you need to find out the cause of this issue and perform Data Recovery through fixing it.

Root of the problem

As stated in above error message, boot errors generally occur due to hard drive failure. The failure can be either logical or physical:

• Logical Failure- Such type of disk failure occurs due to virus infection, file system corruption, operating system malfunction, and disk metadata structure corruption. In these cases, operating system can not read files from the drive and data loss occurs. You can recover lost data using Data Recovery Software. The applications are pretty easy to use and work in most of the logical failure situations.

• Physical Failure- This type of failure is caused by read/write head crash, spindle motor damage, actuator arm damage, power surges, and natural disasters. Data Recovery Services professionals help you to get your data recovered in such circumstances.
