Hard disk failures are far from necessarily fatal: there is almost always a good chance of recovering information. Choosing the right way to recover data is easy if you know the exact cause of problems with the hard drive.
Loss of files due to the failure of the hard drive is not attributed to pleasant life episodes, but, having decided to knock on the door of the data recovery company, do not forget that in this situation something also depends on the user. It is unlikely that you will be able to do all the restoration work on your own, but it is within your power to determine the causes of what is happening in order to estimate the cost of services more correctly. The more accurate the diagnosis is for hard drive recovery the more positive the outlook.
Attentive user is able to find out the cause of the breakdown. Perhaps an electrician failed (for example, a computer power supply), and this caused damage to the circuit board? Or maybe the hard drive failed after driving on a bad road or, for example, dropping a laptop? Even minor vibrations risk turning into serious damage to the drive, disrupting the alignment of the plates or damaging the read or write head. Depending on the situation, you can realistically assess the chances of success in a specialized company.
Try to boot the disk:
Sometimes the drive is not accessible due to damage to the boot sector. Such cases fall into the category of logical data problems, when the services of specialized companies are not mandatory, especially if you have enough experience in solving non-standard computer problems. Try booting your computer from the live cd and, if everything worked out and the hard disk is detected in the hardware list, try using specialized data recovery software.
Analyze the signs of failure:
Problems with the hard disk always have several pronounced symptoms. Strange clicks, some kinds of loading errors, etc. indicate mechanical damage inside the device. They are beyond the power of the user – subsequent disk operations should be carried out in a clean room in a specialized company to recover data from hard drives. If the specialist has agreed to take the hard drive to work, do not forget about the principle of payment only for the result.
In no case do not open the hard drive
This can seriously worsen its condition, and hence the chances of data recovery. And do not forget to choose the right company: with a good reputation in the industry and recovery experience in the most difficult cases.
Under no circumstances open your HD or ask someone without the knowledge to open, in these cases lead to a company qualified and specialized in the subject, because the opening in the wrong way can compromise the HD.
Non-Specialized Companies
Several computer companies in order to solve the problem of their customers, use free programs downloaded from the internet to try to recover the information, but this done in the wrong way, can jeopardize all the recovery of your disk.
