Recover data from hard drive Hard disk, as you know, is designed for permanent storage of information.And unfortunately, there are situations where this storage medium fails.How to save all the data that has been recorded on the hard drive?Try to understand, possible to recover data from the hard disk .

Hard Drive, also known as hard drive or hard, - very sensitive.If it is very simplistic to consider it a device that you and I see that is the hard disk of several thin magnetic disks ("pancake"), readers of magnetic heads and chip control.Hard disk platters and heads are in the so-called hermetical, i.e. hermetically packed and not in contact with the external environment.Damage to one of these parts leads to failure of the entire hard disk.

recover data after physical damage is very difficult , and sometimes impossible.Independent attempts to correct damage in containment or extract data from the disk can only lead to irreversible loss of information because such operations can be carried out only in special "clean" room.

fault in the control chip can try to fix yourself. In this case, the main thing - is the ability to tinker with the help of hot air soldering station and the availability of donor hard drive health.

With donor drive disk- and "patient" are removed board controllers.ROM (read only memory) failed disk using the Hot Air Station "removed" and "sits" on the charge controller serviceable hard drive.This step is necessary because almost all modern hard drives have their own unique settings and options that are just in the ROM.After the ROM has successfully been moved to the corrupt payment to a serviceable, can be connected to a working card to the hard drive.Data successfully saved.

addition to hardware failures and disruptions cause loss of data on the hard drive can serve software failures , and just accidental erasure user.In such cases, you can try to restore the data using special software - utilities for data recovery .

Selecting utility to recover data from the hard disk depends on the situation.Tools for data recovery and may be commercial free.Typically, free functional utility is somewhat lower than that paid analogues.

Thus, data can be lost due to a failure service area of ​​the hard disk, hard disk format, breaking the logical structure of a hard disk as a result of a computer virus.For each of these cases has a program to recover.For example, among the free tools for recovering data from a hard drive are known:

TestDisk - to recover lost partitions and restore boot records on discs caused by improper actions of programs, or human viruses (for example, the removal of the partition table).

SoftPerfect File Recovery - to restore accidentally deleted files from hard disk and other media.

Pandora Recovery - to restore deleted files from hard drives formatted in for NTFS.

PC Inspector File Recovery - to recover accidentally deleted files, data recovery as a result of damage to the file system or format the disk to recover the logical structure of the disk.

Important! fewer disk access happens after the data loss, the better the chances to restore the lost information completely.So it's best to write or install the utility not to recover disks, and on the other, defective disk or on a bootable floppy disk (can work under DOS or Linux), and he restored the drive is connected to a computer with a working hard drive.You can also connect to a computer hard drive recoverable second drive.The main thing - to appeal to the recovery of a disk came from a different disc!
