Distinguishing Between Data That Can and Can't Be Recovered

1) Logical data loss: Logical data loss occurs when the data itself is damaged, but the drive may not be affected and can still completely intact.

Accidental formatting of the partition or disk: This is one of the classic cases of clumsy operation, and still surprisingly common. The place is busy data to the disk as being free for use by this action shows, but they are still there in the disk, even if not in the same place everymore. The FAT addresses of files have changed, but they can still be found and recovered.
Virus attack: A virus is a program that automatically writes over and over again to infect deletion, system files, and in this process. It is strongly recommended that all corporate houses of viruses infect recourse to professional help and report the incident to law enforcement. Your data can be secured at the time, but if you do not help in the detection ofAttackers could be worse damage by the same perpetrators of tomorrow.
Malicious formatting: Not all cases of malignant formatting can be restored, but would be a really good company, able to recover most of it, because it is not so easy to delete all the contents of a disk.
Fragmentation: It can be a painful process, but fragmented files can be recovered if the process were not addressed thoroughly.

2) physical loss of data: As the name implies, thisCase, the disks are physically affected, but the attack / damage is not directly on the data. But this kind of damage is also more difficult to recover himself.

Impact: Contemporary systems are very robust and can hold up to 300g shock. It is advisable to only set the affected object to improper handling. If you do further damage by tinkering in itself, you have to lose your insurance!
To have a fire watch, even if the devices as they roast, try to figure out not toDisk itself. If the temperature does not exceed the melting point of iron, the data to it. Water is bad for the implementation of the fire, because it can leak through the cover and enter on the surface of the plate itself.
Water: There may be instances when the water itself is the agent of harm. In this case, the state should be kept wet because the water leaves a coating of foreign matter when it dries, and corrodes the metal. To keep a soaked wet computerHand until they are about to exploit.

Data that can not be restored

Unfortunately, not all data can be restored. Here is a list of hopeless cases:

Logical loss of data: There are two ways to destroy the data - precipitation and overwrite. In the first case, the data will be deleted again and again, until her "piece" is so fragmented that they can no longer recognize. Likewise, there are certainTechnologies, for example, certain makes of digital cameras, the space by lead in comparison with previous data. In this case, the overwritten data will be lost.

Physical loss of data: The data can be lost if water is on the surface of the disk in and it dries. Likewise, a slice of melted dead. If the vertical effects of the fall is greater than the speed of the read head, then the data is as "slamming" of the disk.

Miracles and Statistics

The recycling rate for businesses in the UK is very good, as you reach the top companies for up to 90% data recovery. The BBC provided a list of the top ten data recovery miracles of 2006. It featured a man from Scotland, took over his laptop twice, an angry old woman, open the keyboard and snatched it away from because her son was not the computer functions properly, and a director of the company, the laptop slid into the bubbling bathtub, while he tried toto multi-task in the bathtub. 11% of all damage done to computers caused by humans. Unfortunately, the chances of recovery are very slim, unless immediate measures are taken. So if you are a miracle, do not try to work it themselves.
