Data Recovery after a Full Hard Drive Format



Data Recovery after a Full Hard Drive Format

Here is an unpleasant yet rather mundane scenario. One day you go looking for an important file — and alas, you discover that the hard drive, which contains it, has been formatted. Maybe you formatted it along with other disks, maybe you decided that those files were obsolete, or mistakenly hoped that you have a backup somewhere safe. Whatever the reason behind this scenario, the grim reality is that instead of having an important file, you find yourself essentially file-less.

Nonetheless, you should not panic. There are numerous ways to deal even with such an unpleasant situation. We tend to think that formatting destroys all traces of data on the disk. However, it is not necessarily true. On the contrary, you can attempt to recover formatted hard drive data with specialized recovery utilities. Armed with versatile utilities and useful knowledge, you may be able to restore necessary data even.

Formatting: How Does It Work?

Firstly, we need to understand its exact consequences. How does it erase your files? In most cases, quick formatting does not transform the files themselves. It merely manipulates the referencing system, deleting the labels of the files. Hence, the files themselves remain on the very same disk, unchanged yet forgotten by the system.

Therefore, should you be able to restore those labels, which provide the system with the links to the files stored on the hard drive, you would also recover the said files. Now we know that formatting does not always erase data from the disk: instead, it often merely destroys the map, which contains their exact coordinates, especially when we are talking about the quick formatting process.

However, we also delete such files by overwriting them with new ones. In this case, the system actively changes the configuration of the hard drive, creating new structures. Because of this, you should immediately stop using the hard drive with lost data. You may have a decent chance to restore valuable data but the complexity of such a task will increase manifold after overwriting old files with new ones.

Specialized Tools for Data Recovery

Hence, how to recover files after formatting hard drive? You will have to use a specialized software tool capable of scanning your hard drive and finding traces of seemingly destroyed files. Choosing such a program is quite a task, which requires careful planning and consideration. Here you can find a detailed guide on the best available programs that may help you recover files from a formatted hard drive. Some of these tools allow you to restore entire partitions whereas a few of them come with a targeted scanning option, which makes it possible to look for specified files while also ignoring all others.

However strange it may sound, it is typically easier and faster to restore an entire partition instead of one single small document. Why does it happen? When you are looking for specified files, the program has no other choice but to scan the entirety of the disk. On the contrary, when dealing with entire partitions the program may skip long scanning: it only has to find both the beginning and the end of the partition. By recovering it, the program will also restore all the files located inside. Of course, it works only if all the files remain on the disk.

Complicated Scenarios

Fortunately, the contemporary market can boast of a great number of various utilities for formatted hard drive recovery. Although such an abundance creates its problems (it may be difficult to find the best option among dozens), you may also look for guides on how to choose the most finely tuned hard drive data recovery software.

However, it also happens that the hard drive resists all attempts to obtain access to valuable data. Such situations are not as common as they may seem, and in most cases, powerful recovery tools provide users with optimistic chances of restoring their data. Regrettably, your chances to restore important files remain minimal in the following situations: 

  • Extensive damage. Hard drives, possibly except for specialized models, are very fragile. Extreme temperatures, hits and smashes — all these factors directly decrease the safety of your data. Once your disk has been physically damaged, your chances of restoring data from it drop to almost zero. If such is the case, you may want to contact experts in the sphere of data recovery. Nonetheless, the chances of successful restoration remain minimal.
  • Secure formatting. Instead of the standard approach, this process not only erases the pointers, which tell your operating system about the location of all files in the partition but also overwrites the disk with new random data. Hence, it deletes files not only from the reference system but also from the disk.
  • SSD TRIM. TRIM is a wonderfully convenient feature, which greatly increases the performance of your SSD. The sad reality is that it also wipes out all erased files from the disk. This option is active by design: once you enable TRIM, you can forget about all deleted files on the disk. As it often happens, better performance comes at the price of data safety.

In Conclusion

As we can see, a patient user with a necessary set of software tools may successfully recover lost data from a formatted hard drive. However, it does not mean that you can forget about backups and diversification of crucially important materials. The best way to deal with a problem is to prevent it from happening. Advanced data security protocol requires a multilayered approach, which balances both the application of modern data recovery tools with regular backups.
