Why might data destruction be necessary?
The need to completely delete files usually arises in the following cases:
You are selling a computer, and you don’t want anyone to be able to recover your personal files that were once stored on your hard drive (photos, letters, documents, etc.).
I know that many will say to this: “this is paranoia, who needs your files? :).”
And yet, there is a possibility that the new owners of the computer will restore your files. And if such a possibility exists, then their attempts at recovery must be nullified. It’s unlikely that anyone will like it when strangers delve into their personal photographs and documents, right?

1) Download the program and run it. It is ready to use immediately (no installation required). This “picture” will appear before you:
2)
Here you only need one button, “Start”. Click on this button.
You will see a list hard drives. The very first column displays the hard drive number; select the drive on which you want to destroy information and see what number is assigned to this drive.
3) Enter the physical disk number and click the “Apply” button.
The program will ask you to confirm the selected action.
And attention again!!! This is the last moment you can change your mind. Once you confirm the destruction of data, there is no turning back! So think carefully about whether you indicated the right disk number, or maybe you shouldn’t do this at all? Just in case, do it backups important files.

Download the program for complete removal files:
Eraser program- guaranteed removal of confidential information. The Eraser program is a specialized tool that is designed to ensure the security of confidential information. It allows you to delete information located on your computer’s hard drive with a 100% guarantee.
For this purpose, special software algorithms are used that rewrite the data several times using the selected method. As a result, it will be impossible to recover the information. Accordingly, it will not fall into the hands of intruders or people who would like to get acquainted with the files.
The great advantage of Eraser is the perfection of the methods that are used to reliably delete information. They are developed by qualified specialists, so they are used even in government agencies. The software algorithms used make it possible to permanently clear the remains of deleted data located on the hard drive space. All magnetic traces are carefully erased, since this requires repeated overwriting. No other method of data removal is as effective.
Also, the described product has a simple interface, so almost anyone can use it on their computer. Even if questions arise, you need to read the Eraser HDD instructions; how to use the program will become immediately clear. And if you observe problems at work, it is recommended to write to email address developers, which is located on the official website of the program described. As a result, specialists will tell the user what the problems are and provide effective way their decisions.
Who may need the Eraser program
Possibly average computer user will pass by this software product. However, people dealing with highly sensitive information will undoubtedly be interested in Eraser. For example, it is installed by human rights activists who have files on their computer hard drive with materials from court cases, data on the preparation of campaigns, and various financial documents. After use, such files must be disposed of so that the information does not fall into the hands of people who are able to use it for bad purposes.
Unfortunately, the standard "Trash" of the operating system cannot provide the function of securely deleting files. And even the Shift + Delete combination is not guaranteed to erase information from a computer hard drive. Indeed, in such cases, only the header and records about the location of the corresponding bits on disk space are lost. It remains possible to restore files using specialized software. But the Eraser program prevents this possibility, since it repeatedly overwrites each bit of the file with empty “zeros”. 
How to use Eraser correctly
- The first thing you need to do is download the product from the developer’s official website to your computer and run the installer. The installation is quite simple, so additional description does not need. It is only worth noting that in its process the user is given the opportunity to embed a program button in the Explorer context menu. It is recommended to activate this function if you plan to work with Eraser quite often in the future.
- After installation, the program shortcut will appear on the desktop, as well as the Start menu. To start, you need to click on it and wait until a new window opens. It will present a list of hard drives connected to personal computer. The user needs to select exactly the disk on which he plans to destroy confidential information. And then double-click on its name and use the cursor to select the files to be deleted.
- After the above steps, you need to think again about how appropriate it is to delete information. After all, this action is irrevocable. If you select it, then you will not be able to recover valuable data by any means, even if you take the hard drive to service center and ask specialists about it. After careful consideration, the user is required to press the "Clean" button and wait until the software algorithms complete reliable removal files.
The main advantages of the Eraser program 
- When using a program privately, you can add it to the Explorer context menu. After this action, there is no need to click on the shortcut in the Start menu.
- The user is able to get rid of both separate files, and entire directories. There is also the ability to clean marked partitions of your computer’s hard drive.
- Eraser can automatic mode Eliminate files in the Recycle Bin. This allows you to save disk space and protect against the spread of valuable data.
- Supports work with almost all types of electronic storage devices. Including flash drives, hard drives, rewritable optical disks etc.
- The product is guaranteed to delete data. Subsequently, no method will allow you to restore the destroyed information, even a visit to a specialized service center.
Deciding to cleanse HDD, users usually use formatting or manual removal files from the Windows Recycle Bin. However, these methods do not guarantee complete erasure of data, and with the help of special tools you can recover files and documents that were previously stored on the HDD.
If you need to completely get rid of important files so that no one else can recover them, standard methods operating system will not help. For these purposes, programs are used to completely delete data, including those deleted by conventional methods.
If files have already been deleted from the HDD, but you want to erase them permanently, then you need to use special software. Similar software solutions allow you to overwrite files so that later they will be impossible to recover even with the help of professional tools.
In short, the principle is as follows:
- You are deleting a file "X"(for example, through the “Trash”), and it disappears from your field of view.
- Physically it remains on the disk, but the cell where it is stored is marked free.
- When new files are written to disk, the cell marked as free is used and the file is overwritten "X" new. If the cell was not used when saving a new file, then the previously deleted file "X" remains on the hard drive.
- After repeatedly overwriting the data on the cell (2-3 times), the initially deleted file "X" finally ceases to exist. If the file takes up more space than one cell, then in this case we are talking only about a fragment "X".
Therefore, you yourself can delete unnecessary files so that they cannot be restored. To do this, you need to write any other files 2-3 times to all the free space. However, this option is very inconvenient, so users usually give preference to software tools that, using more complex mechanisms, do not allow recovery deleted files.
Method 1: CCleaner
A well-known program designed for cleaning hard disk from garbage, and also knows how to reliably delete data. At the user's request, you can clear the entire drive or just free space using one of four algorithms. In the second case, all system and user files will remain untouched, but the unoccupied space will be securely erased and inaccessible for restoration.
Method 2: Eraser
Eraser, like CCleaner, is easy and free to use. It can reliably delete files and folders that the user wants to get rid of, and in addition to this, it cleans free disk space. The user can choose one of 14 deletion algorithms at his discretion.
The program is built into the context menu, so by clicking on unnecessary file right click mouse, you can immediately send it for deletion in Eraser. A small minus is the lack of Russian in the interface, however, as a rule, basic knowledge of English is sufficient.
Method 3: File Shredder
The File Shredder program is similar in its operation to the previous one, Eraser. Through it you can also permanently delete unnecessary and confidential data and erase free space on the HDD. The program is built into Explorer and can be called by right-clicking on an unnecessary file.
There are only 5 erasing algorithms here, but this is quite enough for safe removal information.
Note: Despite the fact that it is very easy to use such programs, this does not guarantee complete data deletion if only part of the disk is overwritten.
For example, if there is a need to permanently delete an image, but the OS has thumbnail display enabled, then simply deleting the file will not help. A knowledgeable person will be able to restore it using a photo that stores sketches. A similar situation is with the paging file and other system documents that store copies or sketches of any user data.
Method 4: Multiple formatting
Normal formatting of the hard drive, of course, will not delete any data, but will only hide it. A reliable way to delete all data from a hard drive without the possibility of recovery is to perform a full format and change the file system type.
So, if you use the NTFS file system, then you need to complete(not fast) formatting to FAT and then again to NTFS. Additionally, you can mark up the drive by dividing it into several sections. After such manipulations, there is practically no chance of data recovery.
If you have to work with the hard drive where the operating system is installed, then all manipulations must be performed before booting. For this you can use bootable USB flash drive with the OS or a special program for working with disks.
Let's look at the process of multiple full formatting with changing the file system and partitioning the disk.
- Create a bootable USB flash drive with the desired operating system or use an existing one. On our website you can find instructions for creating a bootable flash with,.
- Connect the USB flash drive to your PC and make it the main boot device through BIOS.
In AMI BIOS: Boot > 1st Boot Priority > Your flash
In Award BIOS: > Advanced BIOS Features > First Boot Device > Your flash
Click F10, and then "Y" to save settings.
- Before Windows installation 7 click on the link "System Restore".
In Windows 7 you are taken to "System Recovery Options", where you need to select the item "Command line".
Before installing Windows 8 or 10, also click on the link "System Restore".
- From the recovery menu, select "Troubleshooting".
- Then "Extra options".
- Select "Command line".
- The system may prompt you to select a profile and also enter a password for it. If the password is account not installed, skip input and press "Continue".
- If you need to find out the real letter of the drive (provided that several HDDs are installed, or you only need to format the partition), enter the command in cmd
wmic logicaldisk get deviceid, volumename, size, description
and press Enter.
- Based on the size (in the table it is in bytes), you can determine which letter of the desired volume/partition is real, and not assigned by the operating system. This will protect you from accidentally formatting the wrong drive.
- For complete formatting with changing the file system, write the command
format /FS:FAT32 X: - if your hard drive currently has a file NTFS system
format /FS:NTFS X: - if your hard drive currently has a FAT32 file system
Instead of X Substitute the letter of your drive.
Do not add a parameter to the command /q- it is responsible for quick formatting, after which file recovery can still be done. You only need to do a complete formatting!
- After formatting is complete, write the command from the previous step again, only with a different file system. That is, the formatting chain should be like this:
NTFS > FAT32 > NTFS
FAT32 > NTFS > FAT32
After this, the installation of the system can be canceled or continued.
