However, simply by sending files to the Recycle Bin and emptying it, you leave traces of data on the system, which can then be used to recover deleted information. If you are not happy with this situation, then it will be useful for you to learn how to delete files without the possibility of recovery.

Normal deletion

Any user sent files to the trash: to do this, click on it right click and select “Delete”. After this, the recycle bin is emptied, and unnecessary information seems to disappear from the computer.

A warning will appear asking you to confirm the action by clicking “Yes.”

You can configure deletion so that files are not sent to the trash in principle, even without pressing a certain key combination.

Now information will be immediately erased from the hard drive, bypassing temporary storage for deleted data.

Permanent deletion

If you deleted files and then emptied the Recycle Bin, then know that this information can be restored if desired. Fortunately, there are a lot of programs for performing such an operation, both paid and free.

The only way to completely erase information is to overwrite other data in its place. It is advisable to do this several times to completely destroy all traces of the deleted file.

You can't do this manually; but, with the support of special software, you will quickly perform the desired operation.

Recuva

Recuva is commonly used to recover deleted files from a flash drive or hard drive. However, her functionality are often not used full power, because with the help of this utility you can also erase information, leaving no chance of its recovery.

The first thing to do is erase the files in the usual way, sending them to the trash and then emptying it.

To delete data completely, you must first start the recovery procedure:

So, you have received a list of files that can be recovered. Now you need to destroy them, permanently erasing them from your hard drive.

Remember: the more rewrite cycles you specify, the higher the likelihood that the information will be completely and irrevocably deleted. Therefore, select 35 cycles at once and click “OK”.

How to erase data without the possibility of recovery

It is known that information is of great importance. Due to the spread of IT technologies, users store a lot of data on a computer, laptop, removable hard drives and other similar devices. But sometimes important files can be accidentally deleted, in which case you need to restore them. Find out how to recover deleted data from your hard drive here. However, sometimes important information on the contrary, you need to delete it, and you need to make manipulations in such a way that even the most advanced hackers cannot recover the data in the files. Therefore, today we decided to look at ways to erase a file without the possibility of data recovery.

Methods for permanently deleting data

There are three ways to completely delete information from any device. The first of them is mechanical. It lies in the fact that the device from which information needs to be erased suffers mechanical damage, due to which it will not be recoverable. The essence of this method is simple - it is necessary to irreversibly destroy the working surface of the storage medium. Of course, this is the most expensive and rough method.

The second method is called hardware. In this case, the device is exposed to a magnetic field or radiation. This method is also quite expensive, and in order to carry out such a manipulation, you will need special equipment.

The last, quite effective method, which, moreover, can be done at home, is software. In other words, a special software. We will consider this method of data deletion in more detail, since it is the most gentle with respect to the storage medium.

Problems deleting files

Before we talk about how to permanently delete data files, we should say a little about what exactly happens during the process of erasing information. Sometimes it happens that a file cannot be deleted; what to do in this case, read this article. Once you delete a file, the operating system does not physically remove it from the disk. It only marks it as deleted, performing the corresponding operations, including freeing the clusters that belonged to it and file records.

A cluster is a group of adjacent sectors with which the system conducts operations as a whole. A file record describes file attributes and the placement of clusters on disk.

So, after you delete the file, the clusters become free again, which is why they are used by others, again created files, which over time overwrite their predecessors. However, this may not happen soon. In addition, small pieces of information may remain intact, but in some cases it is important not to leave absolutely any data.

Recovery with Recuva

Let's turn to the Recuva program, which makes it possible to restore and delete data. There is both free and paid version this utility. Download this program only from reliable sources, as when downloading the program you may “catch” a virus. Therefore, it is important to install an antivirus program before downloading. Which antivirus programs you can find out here. So, first we just need to remove unnecessary information. To do this, files are selected, and then the Shift+Del button combination is used. In this situation, Shift is designed to ensure that information is not temporarily placed in the trash.

After the manipulations we open Recuva program and search for deleted files. In the window that appears, click the “Go to advanced mode” link, from where we go to Settings.

Here we need a button Reliable removal. You need to select as many rewrite cycles as possible. The higher this number, the greater the likelihood that data will not be recovered. Although, of course, the procedure can take a long time.

You can check how securely the information was deleted if you use the same program, but restore the files. If the utility reports that this is impossible, you have done everything correctly.

Eraser HDD program

Another application that is used for data recovery is Eraser HDD. This program distributed free of charge. In addition, the advantage of the utility is that it is not required to be installed on your computer. This program is easy to use and quite effective.

How exactly to delete information is up to you to decide, and we have suggested ways to do such manipulations. Programs that are designed for complete removal There is quite a lot of information available on the Internet. They are commercial and freely available. At the same time, they will not harm the device while performing all the specified actions, so you don’t have to worry about the safety of your computer or laptop.

Deleting files permanently

The topic of today's article is somewhat unusual. Today we will talk about how to permanently destroy data. Destroy them so that they cannot be restored even with the help special programs or research hardware systems.

Deleting a file is not enough

Regular readers of our site already know that simply deleting a file is completely insufficient from the point of view information security. Deleted files (with rare exceptions in the form of SSD drives) can be restored within just a few minutes. This is due to the fact that when deleting Windows file does not destroy its contents, but simply makes a note in the file system that the file has been deleted and the disk space it occupies is free. Accordingly, the deleted file can be recovered using easy-to-use tools - for example, Hetman Uneraser.

Disk formatting

The very fact that tools like Hetman exist Partition Recovery, is a good indicator that formatted partitions are far from a guarantee of data security. In fact, with the exception of all the same SSD drives, formatting a partition in “fast” mode (and in old Windows versions– and formatting in “full” mode) does not erase data, but only resets the file system. Accordingly, data after such formatting can be restored.

However, it should be noted that completely formatting a disk using Windows Vista and Windows 7 will still overwrite the contents of the disk with zeros, and formatting an SSD disk in any way will most likely (but not one hundred percent) also lead to the destruction of data.

Data destruction programs

There is a whole class of programs designed for reliable and safe destruction of information. Such programs use arrays random numbers to physically overwrite the disk space occupied by the file being destroyed. Some security standards (such as those used by the US Army) require multiple rewrite cycles and insist on the use of cryptographically strong random number generators. In practice, it's more like shooting sparrows from a cannon. For private users and most commercial organizations, a single rewrite cycle will be enough.

Finding such a program is easy - just run a search by keywords"secure file deletion" Free disk space is erased in a similar way - even the same programs are often used.

It should be noted that these methods only work with traditional magnetic drives, in which unambiguous addressing of the physical space on the disk is possible. In case of SSD drives this is not the case, and the destruction of information on them is a separate and rather little-researched topic.

Destroying data on CDs and DVDs

Getting rid of old ones backup copies, do not forget to destroy the data. The most in a simple way destroying information on a CD or DVD means physically destroying the media. Do not give in to the temptation to break the “blank” with your hands - you will most likely cut yourself with fragments, and small fragments of plastic and aluminum substrate will be found in the most unexpected places for a long time.

The easiest way to destroy disks is to use an office shredder equipped with a CD and DVD receiver. In addition to them, there are also specialized devices - by the way, they are not at all as expensive as one might think. For most purposes, it is normal to cut the disc into four strips.

There are also devices that render disks unusable by drilling several holes in them (by the way, you can make holes in the disk yourself using a regular drill). Experts consider this method less reliable compared to using a shredder.

Separately, it is worth mentioning device manufacturers safe storage information. DataTraveler and Silicon Power offer USB or hard disks, which store information in encrypted form. To destroy access to the data of such devices, it is enough to delete the decryption key. Hard drive data recovery software will not be able to decrypt the contents and will be absolutely useless.

We can also mention the heating of the disks, leading to the destruction of the translucent information layer. Like other methods, this method should only be used in specialized devices - overheated “blanks” can quickly melt.

How to permanently delete files

If you read my article “How to Recover Deleted Files,” then you already know that physically deleting data from your computer is not that easy. They are quite easy to restore later. Today I will teach you how to delete files without the possibility of their subsequent recovery.

Some readers may wonder why this might be needed at all. The reasons can be very different. But the most popular option is selling an old computer (or simply digital media, such as a flash drive or hard drive). After all, few people want personal documents, photographs or videos to fall into the hands of strangers.

And some users also store files with passwords from various Internet resources on their computers. Imagine for a second that someone had the data to access your account on the Yandex.Money project or something similar.

Meanwhile, it is quite possible to delete data so that it cannot be restored. For this we need special software. The principle of its operation, as a rule, is that it clogs clusters with fragments of a file that needs to be deleted, with arbitrary information. That is, it physically overwrites it. As a result, even if the file is detected by the recovery program, it will not be able to restore it.

Since our priority is free programs, we will turn to the already familiar Recuva program, which has free version and can not only restore deleted files, but also reliably delete them.

So, to securely erase data, first we simply delete it. To do this, it is best to select the files to be deleted and press the Shift+Del button combination. Usage Shift keys allows you to delete a file without placing it in the trash.

Now we launch the Recuva program and look for the files we deleted. How to do this is described in detail in the article “How to Recover Deleted Files.” But we won’t restore them.

Perform the procedure for searching for deleted files, as described in this article (it is better to search not in a specific folder, but across the entire disk, since the file may have previously been moved). You should get a list of deleted files. Click the "Go to advanced mode" button.

The window will change appearance. As you can see, the “Settings” button has appeared. Click it.

In the settings we are interested in the “Secure removal” item. We must select the number of cycles to overwrite deleted files. The more of these cycles, the greater the guarantee that the deleted file cannot be restored, but it will take longer. In my opinion, it is better to play it safe and choose the maximum number of cycles. After all, we need positive result, otherwise why would we even take on this, right? We select the parameters that suit us and click “Ok”.

We mark the files that we need to securely delete, right-click and in the appeared context menu select the item “Securely delete marked ones”.

When asked whether we really want to destroy these files, we answer positively. And we wait for the procedure for securely deleting files to complete, after which we click “Ok”.

That's all. To check how everything went, you can try to recover your data using the article “How to recover deleted files”. Moreover, if you have used a small number of rewrite cycles, I highly recommend doing this to ensure that your files are truly securely deleted.

If the recovery process fails, then you did everything right. If some files were nevertheless recovered, repeat the procedure again, not skimping on the number of rewrite cycles.

If my article was useful to you, please recommend it to your friends using the buttons social networks or simply by sharing the link.

The principle of its operation (and similar ones) is quite simple: randomly generated information is recorded onto the media, this procedure is performed in several passes (depending on the selected mode).

After the “processing” of the drive is completed, no data recovery program will be able to restore the data previously available on the flash drive.

Instructions for completely destroying files and folders on a flash drive

Launch the utility. In the window that opens, select your flash drive from the list, and then top menu click on the button Wipe Disk.
The Disk Cleanup Wizard will open. In this step select the type file system your flash drive.
In the next step, you will need to select the type of erasure; the optimal option is One Pass Random (quick).
Finally, in the last step, a warning will be displayed stating that all data from the drive being erased will be completely and irrevocably deleted.
And to confirm the start of the drive cleanup process, you need to enter the text “ ERASE ALL" (without quotes), and then press the key Finish.
After the cleansing process is complete, your drive will be completely empty. You can transfer it or give it away without fear that the data that was once on it can be restored.

That's all. If you have any questions, feel free to ask them in the comments.

There are many ways (depending on the device you use) to permanently delete data. This article describes methods for deleting data in mobile devices, laptops and computers running various operating systems(Windows, iOS, Android and Linux).

Drag the files you want to delete onto the Permanent Eraser icon. Find this icon in the Permanent Eraser program folder or in the Dock or Finder sidebar, and then navigate to the file (folder) you want to delete. Drag the file (folder) onto the Permanent Eraser icon.
- Once you drag a file onto the program icon, it will immediately delete the file.
- To display the Permanent Eraser icon in the Dock, open the program's folder and drag the icon to the Dock.
- To display the Permanent Eraser icon in the Finder sidebar, drag the icon to an empty space in the sidebar.
Launch Permanent Eraser and empty the Trash. To launch a program, click on its icon (in the program folder, in the Dock, or in the Finder). To permanently delete the entire contents of the Recycle Bin (and not individual files or folders), confirm your decision in the window that opens.
