|Data Recovery is not always possible but in the majority of cases significant recovery is usually possible if the attempt to recover the lost data is made soon after the data loss occurs. Data can be lost in many different ways, the most typical are:
Simple accidental deletion is by far the most common form of data loss. In most cases if the affected storage device is brought in immediately following the incident there is a near 100% recovery rate.
The next most common data loss occurs when there has been an Operating System Crash or System Crash. In this scenario chances are good that the data is still intact on the hard drive, though it may not be accessible in the standard way. A near full recovery should be possible in the majority of cases.
Virus and Spyware infections can also cause system failures and data destruction. Data recovery in this instance varies depending upon how much damage has occurred.
Typically the most severe data loss occurs when a system experiences a catastrophic hardware failure. Because this type of data loss involves physical damage to the hard drive, in some cases portions of the hard drive can be rendered completely unreadable. To recover data from a physically damaged hard drive requires very specialized equipment and techniques which means that this type of data recovery can be fairly costly. Thankfully, hardware failure is the least common type of data loss.
In every one of these cases, the sooner the affected hardware is brought in for analysis the better the odds are that a recovery can be made. Even in the worst case scenarios, partial recovery should be possible.
Typical types of data that can be recovered include but are not limited to: pictures, music, videos, spreadsheets, databases, letters, and documents of all types.
