I am going to explain when we need to use services of companies, providing data recovery, to pull out most of the data from a hard disk which has failed.

In my opinion, there are three cases concerned with lost data in a computer. The first is, when the computer is not booting because of the Windows corruption. It means there is a software failure. In this case, all your data is still there and the only thing you need is to find a way how to pull it from there.

The second case is such hardware failure, as failed SATA controller or failed hard disk plate. Fortunately, almost all data can be pulled out from there as well.

The worst case is when the hard disk electronics fails, to put it in other words, the controller inside the hard disk fails. Or the head(s) of the hard disk fail. When the heads fails only the data recovery company can help. If the controller fails we can find another working controller and replace it. Still, it is risky.

Our company can help you in two former cases, when the problem is concerned with corrupted, when the Windows are not booting up, and when the hard disk has bad sectors which also prevents Windows from working properly. Please contact us by phone number given.

If you know any efficient data recovery companies which can help with the third case of the data recovery, please write your comments below.

We also do Mac data recovery. As the hard drives of Macs are the same as in PC computers every data recovery method is applicable to hard disks from Macs. There only is a difference between partitions and the manner the Mac OS writes data to the hard drive, while everything else is the same.

I suggest posting a comment about data recovery in London below. As I have mentioned above, our company can provide the data recovery in some cases, but if the hard drive needs a physical intervention, then the other company which specializes in it is necessary to find.
If we do computer recovery, it sometimes means two things. Firstly, recovery means that the computer is recovered back to the factory state. If you do it with a laptop or a personal computer recovery disk, provided by a manufacturer company, it means that all data will be lost because the partition will be erased and the new one will be created. If we do the recovery with windows recovery console, then we replace some Windows files, fix partition and fix registry.
