Recovering Data: Safeguarding your Files

The consequences of an inadvertently deleted file can be anything from a minor inconvenience to a significant monetary loss. At home or at work, deleted files can represent hours or days of effort, wasted. Today, data recovery solutions can restore data files which have been deleted from the hard disk of your computer even if they have been deleted from the recycle bin or by a Shift+Delete keystroke in Windows which bypasses the recycle bin. So if you are wondering how to recover deleted files, there are several solutions that are available.

File Storage and Deletion

Here’s an example of using a data recovery program to recover deleted files:

Recovering data from a hard disk is possible because of the way information is stored on it. When a file is created or copied onto a hard disk, the operating system creates space to be allocated to the file, records the location of the file in a central directory and then places the file in the specified memory location.

When a file is moved, its location in the directory is changed. However, when a file is deleted, it does not remove it from the memory location, it merely removes the directory listing of the file.This means that the file still exists on the hard disk.

How To Recover Deleted Files using Data Recovery Programs

A deleted file remains in its memory location until it is overwritten or cleared from that location. Operating systems like Microsoft Windows use a Master File Table (MFT) to maintain a record of files. The MFT also has a mirror file for when the original MFT gets corrupted. In addition, each file, no matter of what type, has an individual file signature which identifies the file. These two features of files also enable programs such as Advanced Disk Recovery and other tools to retrieve files even after they have been deleted from the hard disk.

The recovery program answers the question of how to recover deleted files be scanning the disk for files and file fragments using these identifiers. Once identified, a program like Advanced Disk Recovery or R-Studio will indicate whether the file can be partially or completely recovered and what percentage of the file may be rebuilt. In many cases, these programs generate a large data dump of file and file fragments with their original paths. In Windows, these may be inspected in the detailed folder view to identify them. If a complete file is restored, it will appear in the folder specified in the program.

Online tools and programs have the capability to recover data from a variety of disk types, operating systems and file systems with basic encryption.

Data Recovery Tools vs. Data Recovery Services

There are several free data recovery tools such as Recuva, TestDisk or Undelete Plus available online. Several others are shareware and limited trial software. These tools certainly help to recover files that have been deleted from IDE hard disks with small volumes of data, rebuild file indices and restore partition and folder information. The cost benefit of using online data recovery tools makes it a smart choice for home or small business users.

The question of when to call in the professionals is pertinent when you need to know how to recover deleted files from RAID servers, laptop or notebook hard disks, NAS or SAN storage, SCSI hard disks or large volumes of data from hard disk arrays. These larger, complex information stores pose a significant challenge to even some of the best tools. Hard disks which have suffered fire, water, fall or scratch damage need professional services to recover data from them.

What the Professionals Do to recover deleted files ?

Today, more individuals, industries and services rely on electronic data storage. From personal music and photographs to industrial strategy and customer records, the appetite for processing power is only matched by the need for storage space. If hard disks contain vital data such as banking or customer records their loss could cause significant monetary and reputational damage. In these cases where data loss during recovery is not an option, the use of professional data recovery services is the recommended choice.

When data is lost, data recovery services analyze the nature of the damage to the storage medium, perform data extraction and rebuild this data and finally deliver the extracted data to the client. Some of these services require low-dust ‘clean rooms’ and sophisticated cleaning and extraction equipment. The cost of these services is significantly higher than do-it-yourself programs and offers a higher success rate for sensitive data. These services also have a no-data, no-cost policy that ensures you are charged only for the quantum of data recovered. They are also able to recover encrypted data.

Beating an Unseen Threat of Data Loss

Data loss is an unseen threat that can be countered using effective recovery tools or with the help of data recovery experts depending on the nature of the hardware or software and damage to the hard disk. These solutions go a long way in safeguarding an individual or business from irreparable data loss.
