Computers are used even in places where we wouldn't expect them like in appliances. Computers make devices more intelligent but also more vulnerable in the case of failure. Take a look at digital cameras. We use giant flash memory cards that can store thousands of images. We expect that they will stay there until we will delete them. However, any camera malfunction may corrupt memory card data and erase files. Fortunately, digital images form memory cards can be recovered. This is possible because in order to completely erase files the memory card would have to be overwritten with new data. In the case of failure this is not what has happened. Usually there is only some corruption at the file system level which can be fixed by digital data recovery. 
The same principle applies to hard drives. All the files saved there will remain where they are until the data is overwritten. Even when you delete file the data remains there, only the file becomes marked as deleted and thus invisible to the operating system. This principle is used to recover files from hard drives and other storage media. However, it can happen that hard drive fails completely. It may be because the electronics has failed or there is some mechanical problem. Fortunately, the data is still saved on the disk platters. The only problem is that we can not access it. The only solution to get the files is to repair the hard drive to the level the data can be read. This can be done by any hard drive data recovery service. They have all the tools and knowledge to recover digital data from hard drives and other storage media. 
To prevent data loss there is one simple and effective solution. It is called data backup. All you have to do is to regularly back up all the important data. It is enough to copy important files to a CD or DVD. Another step in securing the data is to create complete disk images. This way you will be prepared in the case of disk failure. If the hardware has failed or digital data recovery software can not restore the files, you will simply use the latest backup to restore the files. Having own backup of files is the cheapest data recovery service. There are many ways how to make a cheap backup of a hard drive. No expensive hardware or software is needed. You only need to be aware that the failure can happen. Digital data recovery can in many cases restore lost files, but why pay for it when you can create your own cheap recovery solution?
