A program for recovering files from a CD. Recovery of CDs and DVDs

Today DVDs have become somewhat less common. However, they are quite often used for storing information. For example, movies or something like that. It is very easy to damage the surface of this type of media - this is precisely its most important drawback. But it's easy to deal with. It is necessary to use special programs.

There are a huge number of different programs for recovering data from a DVD disc. Some of them are more effective, some less.

Recovery methods

Today, in any applications whose main purpose is data resuscitation, the following methods of working with disks are used:

• restoration of the file system structure;
• recovery of erased file system data;
• signature resuscitation;
• mixed type method.

Some applications can use one method of working with problematic drives, while others allow you to choose the method of operation yourself. Each method has its own merits.

Program overview

Data recovery from a DVD disc is possible using a large number of different applications.

Today the most popular and popular are the following:

• CDCheck 1.3.14.0;
• Bad Copy Pro 4.10;
• ISO Buster.

The CDCheck application allows you to work not only with the type of media in question, but also with many others (flash cards, CDs, hard drives). A program of this type allows you to diagnose the media with the highest quality possible - its speed characteristics, manufacturer, as well as the most likely reason why the data was damaged are determined.



The only drawback is some slowness. But it is connected with a very careful study of the medium and all the information on it. The program is provided on a shareware basis.

BadCopy is an excellent tool for treating carriers of the type in question. Thanks to the wide functionality provided by the manufacturer, the application can revive files of any type without any difficulty. To work with this application, no special knowledge is required - all operations are performed under the guidance of a built-in assistant.

ISOBuster is a utility that allows you to interact with images of seriously damaged disks. This application can work with a file of any extension, be it ISO, MDS or NRG. Moreover, the processing and analysis of all data is carried out extremely quickly. To get started, just insert the media into the drive. The utility's interface is extremely simple and intuitive.

Recovering Data from a DVD Using Applications

The process of data resuscitation usually takes a relatively large amount of time. It all depends on the application chosen for this process.

CDCheck 1.3.14.0

Launch the CDCheck utility. A window will appear on the computer monitor, on the left side of which the disk tree will be located, and on the right side - all kinds of statistical information.



After inserting a drive into the drive, you must do the following:

• select a device;
• click on the “check” button located at the top of the window;
• A dialog box will open where you will need to select the scanning method, as well as the directory in which the data will be saved.



The process itself can be observed in a window specially designed for this purpose - a text log is kept. It displays all the information directly related to the process of reading and analyzing the data present on the drive.



BadCopyPro 4.10

To carry out the process usingCDCheck1.3.14.0, you must perform the following steps in strict order:

• install the problematic media into the drive;
• launch the utility;
• on the left side of the screen we find a shortcut in the form of a laser disk;
• a section called “CDDataRecovery” will appear on the right side; in it you need to select:
  • the drive in which the data storage device is located;
  • suitable recovery mode;
  • click the “Next” button;



ISOBuster

ISOBuster is an equally convenient and functional utility for working with damaged media. .

After starting this program you must:



If necessary, you can cancel copying one file or all at once. There are special settings for this. If the utility detects any bad sectors, the user is prompted to select the operation to be performed - you can try to read the section again, or simply skip it.



DVD-type media are very outdated today. However, they are used quite often. It is very easy to damage these disks, but if necessary, you can read even heavily scratched media using special applications.

Hi all! It’s a shame when the necessary files cannot be read from the disk, but they are not on the computer! How to be? It won’t help here, only the physical will help here disk recovery, and then software. There are many devices for polishing a disc, but what if you don’t have them at hand? That's why today we'll look at how to repair a scratched CD/DVD disc .

How to repair a scratched disk

For the sake of experiment, I took a scratched DVD disc.

To recover cd or dvd disk You need to dilute the toothpaste with plain water in a 50-50 ratio. We mix well. I have green pasta with herbs, it’s expensive, but what can I do)))

Now take a napkin (preferably made of soft fabric, of course) and polish the disc from the center to the edge.

ATTENTION! The movements are as in the figure from the inside to the outside.

You cannot polish using circular movements! You can make the disk even worse. Polish the disc for about 20 minutes, dipping a napkin in water, thereby restoring cd disk. Apply pressure as if you were erasing a pencil from a sheet of paper. Watch carefully to ensure no new dents appear.

Over time, we try to put less pressure on the disk and check that the data on our disk is read. This is how you can restore a completely destroyed disk within two hours. To avoid this in the future, use special bags and bags so that you don’t have to remember the procedure again. disk recovery! Well, then it’s up to the programs, it’s not a fact that the disk has been completely restored, so read on!

How to restore a disc from scratches using the program

Of all the programs, I chose CD Recovery Toolbox. This program is free and simple. Download:

Launch it, select the dvd-rom containing the disc and click next.

We choose where we will save the files from the scratched disk.

Select the files or folders you want to restore. And click save.

The recovery process will begin. We wait until all files are restored to the selected folder.

When all files have been restored, the folder to which the files were restored will open. And the program will display a recovery log, which will contain a video showing which files were recovered and which were not.

Now we look at which files were recovered and which were not. If something was not restored, then we repeat the process from the beginning, only this time restoring unrecovered files. This is how you can restore a scratched disk.

You can also try to restore a scratched disk using a more rigorous method:

Hello.

Many experienced users, I think, have quite a few CD/DVD discs in their collection: with programs, music, films, etc. But CD discs have one drawback - they are easily scratched, sometimes even from careless loading into the drive tray ( I’ll keep silent about their small capacity for today :)).

If we also take into account the fact that disks quite often (whoever works with them) have to be inserted and removed from the tray, then many of them quickly become covered with small scratches. And then the moment comes - when such a disk is not readable... It’s good if the information on the disk is distributed on the Internet and can be downloaded, but what if not? This is where the programs that I want to present in this article will be useful. So, let's get started...

What to do if a CD/DVD disc is unreadable - recommendations and tips

First, I want to make a small digression and give some tips. Below in the article are the programs that I recommend using for reading “bad” CDs.

1. If your disc is not readable in your drive, try inserting it into another (preferably one that can burn DVD-R, DVD-RW ( Previously, there were drives that could only read CDs, for example. More details about this here: https://ru.wikipedia.org/)). I myself have one disc that completely refused to play in an old PC with a regular CD-Rom, but easily opened on another computer with a DVD-RW DL drive ( By the way, in this case I recommend making a copy from such a disk).
2. It is possible that your information on the disk is of no value - for example, it could have been posted on a torrent tracker a long time ago. In this case, it will be much easier to find this information there and download it than to try to restore a CD/DVD disc.
3. If there is dust on the disc, carefully blow it off. Small particles of dust can be carefully wiped off with napkins ( Computer stores have special ones for this purpose.). After wiping, it is advisable to try reading the information from the disk again.
4. I should note one detail: it is much easier to recover a music file or movie from a CD than any archive or program. The fact is that in a music file, if it is restored, if some piece of information is not read, there will simply be silence at that moment. If a section of a program or archive cannot be read, then you will not be able to open or run such a file...
5. Some authors recommend freezing disks and then trying to read them (arguing this by the fact that during operation the disk heats up, but after cooling it, there is a chance that in a few minutes (until it heats up) the information can be pulled out). I don’t recommend doing this, at least until you’ve tried all other methods.
6. And lastly. If there was at least one case that the disk was inaccessible ( couldn't read, an error appeared) - I recommend copying it completely and rewriting it to another disk. The first bell is always the main one :)

Programs for copying files from damaged CD/DVD disks

1. BadCopy Pro

BadCopy Pro is one of the leading programs in its niche, which can be used to recover information from a variety of media: CD/DVD drives, flash cards, floppy drives (probably no one uses these anymore), USB drives and other devices.

The program is quite good at extracting data from damaged or formatted media. Works in all popular versions of Windows: XP, 7, 8, 10.

Some features of the program:

• the whole process is completely automatic (especially important for novice users);
• support for a bunch of formats and files for recovery: documents, archives, pictures, videos, etc.;
• the ability to restore damaged (scratched) CD/DVD discs;
• support for different types of media: flash cards, CD/DVD, USB drives;
• the ability to recover lost data after formatting and deletion, etc.

2. CDCheck

CDCheck- this utility is designed to prevent, detect and recover files from bad (scratched, damaged) CDs. Using this utility, you can scan and check your disks and determine which files on them have been corrupted.

If you use the utility regularly, you can rest assured about your disks; the program will promptly notify you that data from the disk needs to be transferred to another medium.

Despite its simple design (see Fig. 2), the utility does its job very well. I recommend it for use.

3.DeadDiscDoctor

This program allows you to copy information from unreadable and damaged CD/DVD disks, floppy disks, hard drives and other media. Lost sections of data will be replaced with random data.

After starting the program, you are offered three options to choose from:

Copy files from damaged media;

Make a complete copy of the damaged CD or DVD;

Copy all files from the media, and then burn them to a CD or DVD.

Despite the fact that the program has not been updated for a long time, I still recommend trying it if you have problems with CD/DVD discs.

4. File Salvage

Website: https://www.softportal.com/software-5538-file-salvage.html

To give a short description: File Salvage is a program for copying broken and damaged disks. The program is very simple and not large in size (only about 200 KB). No installation required.

Officially works in Windows 98, ME, 2000, XP (I tested it unofficially on my PC - it worked in Windows 7, 8, 10). Regarding recovery - the results are very average, with “hopeless” disks - it is unlikely to help.

5.Non-Stop Copy

Despite its small size, the utility very effectively recovers files from damaged and hard-to-read CD/DVD discs. Some distinctive features of the program:

• can continue files not completely copied by other programs;
• the copying process can be stopped and continued again after some time;
• support for large files (including more than 4 GB);
• the ability to automatically exit the program and turn off the PC after the copying process is completed;
• Russian language support.

6. Roadkil's Unstoppable Copier

In general, this is a very good utility for copying data from damaged and scratched disks, disks that refuse to be read by standard Windows tools, and disks that produce errors when reading them.

Rice. 7. Super Copy 2.0 - the main window of the program.

Another small program for reading files from damaged disks. Those bytes that will not be read will be replaced (“filled”) with zeros. Useful when reading scratched CDs. If the disc is not badly damaged - then on a video file (for example) - after restoration there may be no flaws at all!

That's all for me. I hope that at least one program will be the one that will save your data from the CD...

Happy recovery :)

Scratched your CD/DVD disc? Can't be read by the drive? Why are you so careless about storing it? We will restore the disk, or rather the data from it.

Surprised? Are you taking the disc to the trash can already? Stop! You can get most of the information back from it. How to recover a scratched unreadable disk?

There are many ways. I'll tell you about some now. We will be helped by a wonderful program for recovering data from damaged disks - AnyReader. She is one of the best in this field.

The first thing I advise is to lower the read speed of the drive. Sometimes it helps. If the CD/DVD disc is still not readable, then we move on to harsh actions.

I have brought more than one data carrier back to life, simply by polishing it with ordinary toothpaste and a handkerchief. A little water and paste, plus patience for 30-40 minutes and the result is amazing.

The only important thing is that the movements should not be too fast, but always from the center of the disk to the outer edge and back. Otherwise, only lengthen the scratches. After all, the drive reads disks in a circle. A flat surface under a suffering round plastic product is important. At the end of the torture, rinse thoroughly under running water and wipe dry.

When preparing the material, I saw several ways to restore damaged, worn-out disks. Who, for what...

USEFUL VIDEO

Some polish jeans, without paste. Others rub scratches with teaspoons and treat them with felt. Still others, they cover the damaged areas with green paint so that the laser does not go astray. They will go to great lengths just to save the data.

We use a utility specifically designed for this mission - to repair a scratched, unreadable CD/DVD disc.

Download AnyReader

You can download the program from manufacturer's official website. Or using the search.

Unpack archive and copy the file...

...to a previously created folder (do not move it anywhere). Click on the shortcut and another one appears in the new folder...

Don't worry - that's how it should be. You can look into it, but there is nothing interesting there. AnyReader program started...

Choose the appropriate option and press the button indicated by your finger...

We mark the file that you want to extract from the damaged media (I show the example of the first point)…

Specify the location where to save the recovered file...

...I chose the wrong location in the previous action - no problem...

Now you know how to restore a scratched, unreadable CD/DVD disc (data from it).

To avoid getting bored with the window, go to...

There are many reasons for information corruption. However, regardless of the degree of damage to the mirror surface, it is almost always possible to save data. This can be done in various ways. There are specialized applications that make it possible to resuscitate information even from almost unreadable blanks.

Causes of disk damage

The following situations most often arise:

• there are problems with the drive;
• the CD has a large number of scratches;
• cracks;
• the substrate is damaged;
• there was a failure during recording;
• The RW blank was erased for subsequent rewriting to it.

Photo: data loss percentage

In each of the above cases, the contents can be saved in various ways. The easiest way is to use programs to recover data from CDs and DVDs. There are also various mechanical methods - the impact is carried out directly on the unreadable surface.

Drive problems

Often the problem is not with the CD, but with the drive.

There are many reasons for this situation:

• low quality optics used in the device;
• the correction algorithm is not powerful enough;
• There are dust particles or other foreign objects on the focusing lens.

To test devices for working with the media in question, you just need to try reading the drive on a different drive.

If this succeeds, then the device is to blame. Otherwise, the reason lies directly in the blank itself. This situation can be resolved by lowering the spindle speed - the lower it is, the higher the probability of successful reading.

Surface contamination

One of the most common causes of reading problems is surface contamination. Most often there are fingerprints or the most common dust. Dealing with this kind of pollution is quite simple. It is enough to carefully wipe the surface with special wipes for cleaning office equipment, then repeat the process with a dry cloth.

It is very important to wipe not in a circular motion along paths, but from the center of the drive to its edge. Since radial scratches, which can be caused when a grain of sand or other object hits the surface of a rag, will cause much less damage than concentric ones.

• Under no circumstances should you use the following substances to remove dirt:
• acetone;
• nail polish solvent;
• petrol;

kerosene.

The substances listed above may damage the material from which the CD/DVD is made.

Gaining access to information is greatly hampered by various types of mechanical damage. First of all, these are the most common scratches. The polished surface is quite fragile, so damage can be done very simply - just one grain of sand is enough.

Mechanical damage can be classified according to their shape and location:

• narrow;
• wide;
• concentric.

Narrow scratches usually do not pose a serious danger due to the large number of various correction algorithms. Wide scratches are more dangerous - the reading machine may simply lose a track, while starting to read the next one.

Concentric scratches cause the most problems. Since they usually damage an entire sector of information.

Most correction algorithms are unable to cope with this type of problem because the positioning system cannot operate normally. This situation can only be resolved by polishing the surface.

Cracks

Another big problem is cracks.

• They come in two types:
• from the center;

from the edge.

With frequent use of the drive at high speeds, defects of this type only get worse. The situation can be corrected with the help of mechanical repairs and special software for resuscitation of information.

Damage to the substrate

Often the cause of problems is damage to the substrate.

Photo: damage to the substrate upon contact

• Defects of this type occur in the following cases:
• storage conditions are not met;

the blanks are of low quality.

Most often, the substrate is damaged due to liquid getting between it and the polycarbonate. This usually occurs due to the lack of varnish coating on the ends, or when the drive is stored in a room with high humidity.

Recording failed

Sometimes a CD/DVD becomes damaged during recording. This usually happens due to a software error or some incorrect actions of the user himself.

• The easiest way to access information is in the following cases:
• additional recording was performed on RW-type multisession media;

An error was made during the current session.

Recovering data from a CD in such cases is usually not difficult. It is enough to use specialized software.

The rewritable disc has been erased or overwritten

Sometimes it is necessary to return information lost when erased or overwritten.

• Such processes can be divided into the following types:
• quick erase;

When using quick erase, data can be partially restored. If full is applied, then the data is lost forever.

Disk recovery methods

At the moment, all resuscitation methods can be divided into the following categories:

• software;
• hardware;
• mechanical.

Program

There is a large selection of different software for resuscitating damaged media. Software of this type simply fills unreadable content with empty bits, or makes copies from neighboring areas. This method is not suitable for all file types.

Each application is quite effective at restoring access to lost content. But this method does not always help - in such a situation it is advisable to resort to a hardware or mechanical method of data recovery.

Hardware

To carry out hardware resuscitation of the drive, utilities are used that have specialized drivers built into them. They make it possible to use cluster reading - this way you can avoid freezing the operating system while working with a damaged disc. Thanks to this type of reading, information loss can be minimized.

Some readers have built-in functions:

• improved focusing of the laser beam;
• ellipsoid compensation.

Mechanical

If the defects on the surface are very extensive, then mechanical restoration - polishing - can be used. To carry out this operation, special equipment is required, as well as extensive experience. Also, all kinds of scratches are repaired in the same way as cracks on car glass - drilling is performed, after which the edges are glued together with polymer.

Copying and reconstruction methods

The copy and reconstruction method can be used in the following cases:

• it is possible to read the TOS, the directory tree - but there is no access to the required files and individual folders;
• when trying to read the drive, the OS freezes;
• The reader tries to access the data at different speeds, but there is no positive result.

If it is impossible to gain access to the TOC, you can use sector-by-sector reading or intelligent processing.

If the media is not recognized, then it is advisable to make an image of it and subsequently reconstruct the damaged areas using special software.

TOC cannot be read, do a hot swap

For successful reading, only three TOC fields are required:

The hot swap process requires the availability of a similar, fully written disk, as well as disassembly of the device for reading.

The hot swap process itself is as follows:

• a new CD/DVD is inserted;
• after reading the TOC is replaced with an unreadable one (the drive will need to be disassembled);
• specialized software for reconstruction is launched.

How to recover data from a CD

There is a large amount of different software available for resuscitation of drives of this type. It can be either commercial or free. This usually does not affect its reliability.

ISOBuster

To resuscitateCD/ DVDwith helpISOBuster, you need to do the following:

• open the utility and select the device in the left part of the window;

• In the right part of the window, call up the context menu for the desired object and click on “create IBP/IBQ image file”.

After the process is completed, you will need to mount the resulting image to work with it.

To resuscitate data usingrequired:

The whole process takes a lot of time. But upon completion, the user will be able to access the files.
