Recover deleted data from hard disk
Data loss from hard drive, unfortunately, incredibly common. If it happened because of his fault, to recover the data you need to contact the service centers which are engaged in extraction of data from damaged storage media.
However, if the Winchester is OK, in most cases, to recover deleted data can be performed independently using specialized software, which will be discussed below.
Reasons for lost files
Causes for data loss from hard drives may be different. They are divided into two categories: mechanical and software.
Mechanical causes include:
- the failure of the hard drive controller.
The second reason involves software failures and user errors:
- computer viruses;
- sudden power outages;
- accidental removal.
Deleted files disappear completely
If data gets lost due to error, formatting or accidental deletion, they can be fully restored. For example, when formatting the data itself is not deleted, erased only the header, which contains information about finding them on your hard drive.
The same applies to accidental deletion. The operating system marks the sectors in which data is stored, ready to record and displays them as free space. In this case the files remain on the HDD until they are sectors with new information.
In some cases, even when the mechanical damage, such as shocks, you can recover data from hard disk, but this is only the service centers.

What if important information is deleted
The most important thing is not to panic. The probability of recovery that deleted file is very high. Users in this case there is a reasonable question: how to recover data? Come to the aid of special programs that scan the specified region of the hard disk and will help you to perform recovery even after formatting.
To reduce the risk of a complete loss of information, must adhere to the following tips:
- you need to delete the copy on that new information that may lead to the replacement of the sectors with deleted data with new ones, then get them will be difficult;
- you can’t defragment, as it performs a reallocation of disk space, which reduces to zero the chances of recovery;
- it is desirable to minimize user activity, especially in applications that use temporary files (e.g. web browsers).
Overview and principles of operation of utilities
Recovery tools provide the user with various tools which, with timely usage, gives almost 100% results.
At work they use the following methods to restore:
- reconstruction of the structure of the file system (FS). Used in case of quick formatting or deleting a logical volume. The directory structure is not disturbed, which gives the possibility of restoring whole directories and subdirectories preserving ways.
- file recovery. The method comprises reading of the official records of FS on which the software determines the location and attributes. This method works if no substitute data.
- the ability to restore information to the signature. Performs a sector-by-sector scan for known signatures. However, their paths and names are not stored, and the result is sorted according to their type. Method is used if the FS is damaged, and its reconstruction is impossible.

- regularly clean the temporary files;
- regularly defragment and checking for errors;
- the carrier should always be at least 10-15% free space.
Important! Once the file is deleted, defragment and checking for errors conduct is strictly prohibited! This can lead to full data loss and the impossibility of their recovery.
