Eraser deleting files. Complete hard drive wipe

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 in your work, it is recommended to write to the developers’ email address, which is located on the official website of the program being described. As a result, specialists will tell the user what the problems are and provide an effective way to solve them.

Who may need the Eraser program

Perhaps the 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

  1. 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 no additional description is needed. 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.
  1. 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 the personal computer. The user needs to select exactly the drive 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.
  1. 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 choose it, then you will not be able to recover valuable data by any means, even if you take the hard drive to a service center and ask specialists about it. After careful consideration, the user is required to click the Clean button and wait for the software algorithms to complete the secure removal of 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 individual files and entire directories. There is also the ability to clean marked partitions of your computer’s hard drive.
  • The Eraser program can automatically eliminate files placed 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 discs, 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.

4.1. Eraser program - guaranteed destruction of files and incriminating materials

Recently, in connection with the upcoming adoption of the so-called “Internet law,” the issue of protecting information stored on a computer from unauthorized access and, if necessary, guaranteed complete deletion of compromising files has become very relevant.

In case of danger of PC inspection, one of the most effective methods of protection is to instantly delete all data on the computer’s hard drive. But this can be done in a matter of seconds only using special hardware shredders. The asking price is very high, at least $1000! This is the price of the cheapest of them. This option for instant data destruction is only available to super-rich people and organizations (but there they use it for completely different purposes).

For the average user, the best option would be to use special software to delete data. Why can't I just delete or format my hard drive? The fact is that regular formatting does not completely remove information. It can be restored using special programs.

To guarantee erasure, special programs are needed, so-called software shredders.

For programmatic destruction of information, a huge number of shredders are offered on the market, using different data erasing algorithms and characterized by different reliability (level of secrecy) and speed. All algorithms for deleting information are based on repeated rewriting of information in sectors of the hard disk and provide for writing certain fixed values ​​or random numbers into each byte of each sector of the hard disk.

The best program in this category, in my opinion, is Acronis Privacy Expert Suite. This is a whole package of programs. The main purpose of the Acronis Privacy Expert Suite is to ensure the security and confidentiality of your computer work, and the ability to destroy information is just one of its additional functions. The program impresses with its ease of use. Even a beginner can handle it. There is a detailed hint for each action. But, unfortunately, it is paid. So let's look at another program - Eraser. The program is free. But that doesn't mean she's bad.

The purpose of the program is to permanently delete files and folders from the computer’s hard drive by overwriting the original data with zeros. The program is fast to use and works with any Windows operating system. I recommend downloading the program on my website halyavin.ru in the “Free programs” section. I constantly update software versions. (Fig. 162–164)

After downloading, we begin installing the program. (Fig. 165–170)

The program is installed. In order to delete a file, simply right-click on it (the file you want to delete) and select “eraser” and then “erase” from the drop-down menu. Click on this menu item. The process of completely deleting the file will begin. As you can see, it couldn’t be simpler. I recommend that all users have this program, just in case...

Or documents with passwords.

Or even worse, when your information falls into the hands of not just an ordinary curious person, but professionals who know how to use the obtained data to rake money from you.

You may say, “That would never happen to me.” “I always delete all files” or “I always format the disk before it goes into the wrong hands.” Not so simple. The data still remains on the disk.

When you delete a file, it is not completely deleted. The file data remains on the disk until it is overwritten. Much the same thing happens when you format a hard drive. Most of the data remains the same. The disc is simply completely free for recording.

To protect yourself, you need to overwrite/delete/erase all important information. Also, in the Window OS, you need to clear the “swap file”, as it may contain your confidential data.

  • For data security on large hard drives, one pass of data overwriting is more than enough.

    The best practice, of course, is to regularly overwrite free disk space. I found virtually nothing on the overwritten space of the large disk. After just one overwrite with random data, PC Inspecot File Recovery found nothing useful, or found a bunch of files filled with random data.

    However, on small disks the data can be recovered, it largely depends on the pattern in which the empty space is filled with random data.

  • Since clearing all free space takes quite a long time, you can clean only specific files. For specific files and folders, it will be much easier and faster to overwrite information with random data. However, it should be taken into account that some media use a wear leveler at the hardware level, which may prevent normal disk cleaning.
  • Currently, data cleaning programs also assume that it is necessary to erase data from the download file that is used in the Windows family. This can be done using the Ultimate Windows Tweaker program or by following these instructions:

Clearing the swap file:

2. Go to the key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management"

3. Create or change the ClearPageFileAtShutdown key of type (REG_DWORD) to the value 1

4. Restart your computer

Pagefile encryption (Vista or higher):

1. Launch Command Prompt.

2. Run the command "fsutil behavior set EncryptPagingFile 1".

3. Restart your computer.

  • If you need to erase the entire disk before getting rid of it, then Darik's Boot and Nuke (DBAN) is suitable for you. This utility is specially designed to clean the entire disk. But be prepared that you will have to spend time, since the disk already contains There will be nothing at all, including partitions.

Review of free data removal programs

Eraser is one of the most powerful tools for secure data removal

More programs for securely deleting data

  • Revo Uninstaller (from the review of uninstallers): includes the "Unrecoverable Delete" utility for overwriting files, as well as the "Evidence Remover" utility for cleaning up free space.
  • Recuva (from a review of file recovery programs): A program for file recovery. But it can also delete files found during recovery.
  • EraserDrop: Has a good drag & drop interface. Allows you to quickly delete unnecessary files. Supports Windows 2000/XP/Vista/7.
  • UltraShredder: A small program. Easy to use. And it can work from a flash drive. Supports Windows XP/2000/98/98SE.

An alternative with a slightly different plan is (DBAN). It is used to create a floppy disk (rare) or CD to automatically clean the hard drives of any computer that has been booted from them. A great tool if you need to clean many computers, as well as if you quickly need to delete important information. However, in the hands of a beginner, this utility can become a dangerous weapon.

Good to know about secure data deletion

Do I need to do 35 passes?

If it's quick, then no. The current sizes of hard drives are becoming quite huge. And the chances of just finding 10Kb of your data on a 500GB disk are quite small. Therefore, several passes to fill with random data will be quite enough.

Why is it necessary to wash? Just to know what you deleted? Or that I have good manners?

  • Stealing information is not paranoia. This is reality. Your information can be accessed by a virus that can easily crawl through your hard drive in search of a certain type of information. Or the person who got your hard drive can easily see what was interesting on it before.
  • When I delete a file, that means I delete it!!! I don’t store it somewhere in a basket, or wait for someone to restore it. True, sometimes this is for the better.
  • There are some types of programs that restore themselves after deletion, due to the fact that the file itself is not physically deleted.
  • To protect confidential information from unauthorized persons.
  • Some organizations require it as per their security policy. However, some of them may require more extreme actions.

Did you know that after deleting a file, you can restore it using special programs? Even formatting won't help. If you need to permanently delete some files, you need to use a special program.

This article will look at Eraser HDD, a free program for destroying information on a disk without the possibility of data recovery.

Attention! This program will destroy all files on the selected hard drive.
Destroyed files cannot be restored!
Use it if you really need to completely destroy your data.

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?

How to use Eraser HDD program

In fact, it is very simple to use; you only need to press a couple of keys.

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 of 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, make backup copies of important files.

4) If you finally decide and confirm the deletion, wait for the following message to appear:

Now all you have to do is reboot and initialize the disk.
