Sometimes, electronic storage devices fail to serve the purpose and result in corrupt data files or even loss of important data. Typically, data losses take place because of the following reasons:

  • Human error Data deletion or overwriting due to accident
  • Corrupt file system Operating system crash, computer viruses
  • Hardware failure HDD failure, CPU failure
  • Location-related fire, flood, electricity outage

The hard disk is one of the most commonly used electronic storage devices owing to its ease of use and the varied number of file systems available for storage. When it comes to data loss, the implications can be anything from just losing a good collection of movies or family pictures to vital business data which affect the normal functioning of a corporation. Times like these make the user wish that there was something that could recover the files from the device. Fortunately, there are many recovery applications which are efficient at HDD data recovery. They work solely on the basis of the fact that files deleted are never really gone unless they are overwritten by other files.

The hard drive crash recovery systems rely on the mode of data storage in the hard drive; data is stored in the forms of binary numbers 0 and 1. Files are stored as clusters of binary numbers; when the file is accessed, the system triggers the lead cell of the cluster which displays the contents of the file on the screen. Typically, when a file is deleted or lost, the address of the lead cell is changed to 0 which means that this space is available for data storage. Unless you have overwritten the space, this data can be easily recovered with disk file recovery systems.

HDD data recovery systems, data backup systems, sniffing applications, and data protection systems are all part of a much larger system called Data Loss Prevention. Selecting a good disk file recovery system involves analyzing different parameters like the cost of the software and the criticality of the data. The conventional hard drive crash recovery method is a very complicated and systematic process, and unless carried out by professionals in a controlled environment like the Class 100 room, this process leaves a lot of room for mistakes and deteriorates the chances of disk file recovery. This method involves replication of data from corrupt or damaged HD drives onto another magnetic interface; it is essentially a form of HDD data recovery and works even when there is physical damage to the drive.

The purpose of sniffing software is basically to dig out lost data in the sense that it searches for data clusters of a specific size, determines the lead link of the cluster and changes its address from 0 to 1 making it available for access. Physical damage to the drive renders this method ineffective. In addition to these systems, there are different backup systems which focus more on backing up data than recovering data from damaged hard disks. It would also be worth your while to consider various data backup options for the simple reason that it might not always be possible to recover data.
