What is data recovery? - Data recovery is a procedure to recover data from a computer's hard drive that has been lost due to system failure or mechanical malfunction. Data recovery can also be used to recover data that has been accidentally overwritten or deleted on a computer. There are companies and people that specialize in data recovery, and programs that try to extract data from computers that still have some level of functioning, and many techniques to do it yourself.

Function

The main function of data recovery is to recover data from a damaged hard drive or operating system. These failures refer to physical and logical damage. Often the physical damage causes a logical damage, for example, when a hard drive overheats it causes the programs to malfunction and, finally, causes the operating system to fail. Data recovery involves the use of different methods to intervene the hard drive of a computer and recover lost, deleted or compromised files. The method used to recover this data depends on the type of damage, in cases of physical and logical damage often have to be used several methods to deal with the physical damage first and second, deal with the logical damage.

Techniques

There are several techniques used in data recovery. Sometimes, these techniques are used individually or with other techniques, depending on the type of damage to the hard drive and the amount of money that one is willing to spend to recover their data. Hardware replacement is probably the easiest and cheapest method of data recovery. If a fan is broken and the hard drive overheats, causing a malfunction, the simple replacement of a part solves the problem. Most data recovery specialists first check for hardware damage before moving on to more expensive and slower forms of data recovery. Disk images are frequently used when a hard drive has been physically damaged. This technique takes the data image out of the damaged partition of the hard drive and transfers it to a stable partition. It often does not go through the operating system and goes directly to the hard drive. This technique is not always reliable, it can sometimes cause more damage to an operating system when rewriting sectors and is not able to recover all the data. The restoration of files is done when the damage is strictly logical and the operating system still works. Most computer manufacturers provide data recovery programs in the box with the new equipment which will allow the system to check lost or damaged data in the event of a system failure. One of the problems with these programs is that they will often permanently delete the damaged files automatically. The carving of data is done by data recovery specialists and it really consists of going through each section of a hard drive and searching for specific files. This method is very expensive and time consuming. Recovery software is available for different forms of data recovery in systems that remain somewhat operable or for operating systems that have failed completely. These programs can be used to restart a failed operating system; the system will check for files that are broken or damaged, recover lost image files and recover damaged partitions.

Misconceptions

Professional data recovery can be expensive and time-consuming, so many users try to recover the data themselves. There are many tips on the Internet to recover data, including freeze, tap, drop and spin the hard drive. Although some of these procedures may work from time to time, most of the time they damage the hard drive even more and often lose data permanently. Keep in mind that removing the hard drive from your computer will often void the warranty and end up costing you more in the long term. Another misconception regarding data recovery is that everything is saved somewhere on a hard drive and that it can eventually be recovered. This simply is not true. A scratch on the hard drive can instantly erase data permanently and you will have an overwriting of the computer. Although data recovery systems can often recover most of the lost data, never assume that everything is salvageable.

Prevention

The best data recovery system is one that you can perform on your own, a backup of the data. Backing up files on a regular basis can be a lifesaver, just ask any college student who has lost a job a couple of days before the due date. Make a habit of saving documents twice, one on the hard drive and the other on a portable memory device. There are also several online companies that automatically back up your data either daily, weekly or monthly. The data is encrypted and stored for you and is recoverable from any Internet connection and sometimes from a mobile device.

Warning signs

Sometimes, computers only fail suddenly, for no apparent reason, removing vital data and files without warning. However, there are usually warning signs that a system is about to fail, which will give you the opportunity to back up your data. Warning signs may include a slow start and / or shutdown, freezing, sudden powering down unexpectedly, programs crashing or malfunctioning, loud noises while the computer is running, or There is overheating even though the fan is running constantly.
