How to recover lost data from natural and man-made data disasters

default_clip_image001According to a report, about 32% of all computer users lose their files due to events that are under their control. Different types of data stored on storage media are very vulnerable to several risks, corruption of Windows partitions including corruption of Windows registry, MBR corruption, sudden system shutdown, malicious virus attacks, software errors, natural disasters, human errors, hardware failure, voltage fluctuation, power failure, and so on. Many times, users face problems due to RAW hard disk. When a hard disk partition used in its native mode without having a file system, usually call it as RAW. As there is no file system on it, you come across the message that partition need to be formatted when you click on it. The most common reason is hard disk failure that is mentioned as follows:

Hard Disk Failures:

Physical Failures (Man-made Disaster):

Physical failure of hard disk drive happens due to sudden switch off, power failure, hardware malfunctioning etc. Since data is only magnetic impulses on the surface of a hard disk so they are very vulnerable to surroundings. And, ridiculous handling of hard disk may cause trouble of data loss. Drive Alignment Drift is another reason of data loss problems. The minor changes in the read/write heads wouldn’t affect generally and data still gets written & it will be read later. But, there is some data that scarcely ever gets re-written, and that is the Sector ID Headers.

Logical Failures (Natural Disasters):

  1. Master Boot Record Failure: The master boot code scans the partition table of hard disk for the active partition, finds the starting sector, loads a copy of the boot sector from the active partition into memory and then transfers control to the executable code in the boot sector. If the master boot code cannot complete these functions, the system shows error message of MBR error.

  2. Boot Sector Failure: The boot sector is a specific part of a hard disk, floppy disk, and other similar data storage device. It is loaded to memory and executed as a part of the bootstrap sequence. Mostly boot sector failure happens due to the defection of boot sector virus which is usually spread by infected floppy disks.


  3. Accidentally Deleted Data: Some time, users delete important data without thinking about its importance. When it deleted even from system’s recycle bin, they become unable to access them easily. When you delete your system’s data by pressing SHIFT key, it get deleted permanently which cannot be accessed usually.

  4. Bad Sectors: Bad sectors of a hard disk are a portion of the Hard disk that cannot be used any more. Data stored on bad sectors of the hard disk must be recovered before use as they may get lost.

Solution – Hard Disk Data Recovery:

  • Replace the (Circuit Board) PCB of the hard drive.article-new-ehow-images-a07-74-rt-repair-pcb-printed-circuit-boards-800x800

  • Replace the old Firmware with updated firmware.

  • Replace the Head Stack that causes hard disk head failures220px-Hard_disk_head

  • Move the disk to another Drive

  • Use Data Recovery Software

By applying above mentioned methods you can minimize your data loss trouble. Unfortunately, if you have lost your very important data & you want to recover them at any cost then should look for a trustworthy third party tool. Regular updated backup is the preferred way to handle such data disaster situations but occasionally it may also get corrupted. However, several tools promise for absolute recovery of lost Windows hard drive data but very few of them are effective. Users can resolve logical hard disk failures (e.g. MBR failure) by choosing Recovery mode option offered by the bootable disc of operating system. But, it does not guarantee for complete solution. All the data deleted or lost from the hard disk or other storage media cannot be extracted manually so it is necessary to utilize a proficient third party tool like Kernel for Windows data recovery tool.

Kernel for Windows data recovery tool is professional third party tool that enables you to recover inaccessible or lost image files, video files, music files, document files, database files, email files, media files, archive files, web files and graphic files from Windows hard disk. It is integrated with three effective recovery modes & finally displays all the recovered files in a hierarchical structure to save them at desired safe location. This tool supports FAT 16, FAT32, NTFS and NTFS5 file systems and IDE, EIDE, SCSI, SATA, PEN, ZIP, and USB drives. You should must visit this site for seeing detail
