Download a program for reading worn-out DVDs. Utilities for resuscitation of damaged laser discs
CDCheck 3.1.10.0 - Works with all files - on hard drives, CDs, floppy disks. Another innovation is the comparison of a CD-ROM with a copy located on the hard drive (it performs a bit-by-bit comparison of the data on the CD with their copies on the hard drive.
DeadDiscDoctor 1.0- a utility for copying files and data from corrupted sources. Programs made to suppress (input/output error and file path error). the utility reads the file in 15kb blocks and when the device (CD-ROM, for example) generates an error, the block size is reduced tens of times, everything is repeated, and so on until the block is read without errors. If the block size reaches the minimum, then the utility skips one byte and starts reading from the next. After successful reading, the block size increases tens of times and so on until it reaches a maximum of 10 kb.
File Salvage 2.0- a utility for reading damaged and damaged disks from a group of Light Alloy programmers.
The File Salvage utility can copy any damaged data and files from any media. Unreadable clusters are replaced with zeros. During reading, you can stop the process and then start it again, even on a different drive.
Non-Stop Copy v1.03- the utility allows you to copy damaged data and files from any media, and unreadable sectors are replaced with zero bytes. Also,
tries to recover information from bad sectors. The utility does not use any methods for reading information, as a result of which it will work correctly on any type of storage media and on any data systems supported by the operating system.
Roadkil's Unstoppable Copier 2.2- A utility that recovers data from damaged hard drives, CDs, floppy disks, floppy media.
Skopin FileCopier- during my testing it didn’t show itself on the very good side. When copying a good disk, the speed was very slow—it took 13 minutes to count a 700 MB disc with a movie. When copying a damaged disk, the processor load was 100. I didn’t wait for the copying to finish.
Super Copy2.1- A very simple utility that reads any disk in 20 minutes with large data losses, an ideal utility for quick copying and if quality does not matter to you.

Scratched your CD/DVD disc? Can't read? Well, why are you so careless about storing them? Now we will restore the disk, or rather the data from it.
Are you 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 an unreadable disk?
There are many ways. I'll tell you about some of them now. And 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 reading speed of your drive. Sometimes it helps. If it still doesn’t read, then we move on to harsh actions.
Personally, I have brought more than one disc back to life simply by polishing it with regular toothpaste and a handkerchief. A little water and paste, plus patience for 30-40 minutes and the result is amazing.
The only thing that is important is that the movements should not be too fast, but always from the center of the disk to its outer edge and back. Otherwise, you will only lengthen the scratches. After all, the drive reads disks in a circle. Also, a flat surface under the suffering disc is important. At the end of the torture - copious rinsing under running water and wiping dry, poor fellows.
While preparing this material, I saw several more ways to restore damaged, worn-out disks. Who is ready for what?
Some polish jeans, without paste. Others rub scratches with teaspoons and then treat them with felt. Still others, they cover the damaged areas with green paint so that the laser does not go astray. In short, they go to great lengths just to save the data.
And we use the utility AnyReader, specifically designed for our purpose - to recover an unreadable disk.

Super Copy 2.1 is a program for reading damaged disks and floppy disk-type magnetic media. Tested on CD and DVD discs. Theoretically, copying from BD is also possible. The advantages of this program are that it is: free, works without installation, its size is 408 KB, has a simple and convenient intuitive interface (picture below), there is a help system (but you won’t need it).
Super Copy is a very easy to use program for reading damaged disks.
To run the program, you need a computer with a processor of at least P-166MMX, 32Mb of RAM or higher, 408 KB of hard disk space, optical drive, floppy drive, OS Windows 98/NT/2000/XP/Vista/7. I checked the operation under Windows XP/Vista/7 myself. You may need Administrator level access rights to run. When copying large files (4.4 GB) in Windows 7, the program may crash. The developer declares compatibility with Windows 98/NT/2000 on its website. I think he can be trusted. However, it should be borne in mind that the better your hardware (processor, RAM, HDD (“hard drive”), optical drive, etc.), the faster the copying process will occur. The following factors also influence the copying process time: the size of the copied file, the degree of damage to the media, and the program copy settings.
I saw the “highlight” of this program when I tried to copy a movie from a scratched CD-R disc. Before this, I tried to do the same thing using IsoBuster (a paid and disproportionately more functional program). IsoBuster never worked. The copying process is stuck at 30%. CPU usage was around 100%. As a result of fifty minutes of copying the thirtieth percent, I interrupted the task.
The Super Copy program (then still 2.0) coped with the task with a bang. At the same thirty percent, she “thought” a little, skipped it (replacing it with zeros) and continued copying further. After 20-25 minutes I received a copy of the film on my hard drive. While watching, at about the unfortunate thirty percent, the Windows Media Player flashed a black screen, the sound cut out for a couple of seconds and the film continued.

Setting up Super Copy 2.1
To open the settings window, click the button Tune in the main program window. Or go to menu Tune and select Program parameters(picture below).
The super-copy-2.1 program can carry out the copying process using several methods. Which one to use depends on the specific situation. You can set the reading area (the entire file or up to the first error). You can also set the file reading direction. If you check the " Read from older addresses", reading the block will begin not from the beginning, but from the end, which will significantly slow down the process of reading files, but will reduce the number of errors. If you check the " Abort reading after... seconds.", the program will monitor the reading process from the outside and interrupt it after a specified amount of time. This is a very useful function, since some device drivers take a very long time to process errors. That is, when the program tries for a long time to unsuccessfully read the same section , the reading process will be forcibly interrupted after the time you set. If this does not happen, without interrupting the copying process, you must remove the storage medium from the reading device and, after the message appears, insert it back.
Copy methods
- A method for reading an entire file forward. The file is conventionally divided into blocks. Blocks are read only sequentially in the forward direction and without exception. The block is read until the first error occurs. For example, this method is suitable for reading small files or for detailed damage analysis.
- A method of reading an entire file in reverse. The file is conventionally divided into blocks. Blocks are read only sequentially in the opposite direction and without exception. The block is read until the first error occurs. For example, this method is suitable for reading small files or for detailed damage analysis. If the " ", the block is read backwards, i.e. from large addresses to smaller ones. This allows you to reduce the number of errors.
- A method of reading an entire file first forward and then backward. The file is conventionally divided into blocks. Blocks are read only sequentially in the forward direction and all without exception, then the program will try to read those blocks that could not be read when reading forward. Checkbox " Read from older addresses" must be installed. This method is suitable for reading small files or when there is minor damage to the media.
- A method of reading a file until the first error occurs in the forward direction. The file is conventionally divided into blocks. Blocks are read only sequentially in the forward direction until the first error occurs in the block. This method is suitable for reading heavily damaged media.
- A method of reading a file backwards until the first error occurs. The file is conventionally divided into blocks. Blocks are read only sequentially backwards until the first error occurs in the block. If the " Read from older addresses", the block is read backwards, i.e. from large addresses to smaller ones. This reduces the number of errors. This method is suitable for reading heavily damaged media.
- A method of reading a file forward, then backward until the first error occurs. The file is conventionally divided into blocks. Blocks are read sequentially, until the first error appears in the forward direction, then until the first error appears in the reverse direction. Checkbox " Reverse reading when reading backwards" must be installed. This method is suitable for reading heavily damaged media. (The items “Setting up Super Copy 2.1” and “Copy methods” are taken from the program help).

The laser disc has undergone significant changes since its inception, evolving from a CD with a data capacity of 650 megabytes to a capacious Blu-ray capable of storing up to 50 gigabytes and more. However, despite such obvious progress, optical media has not gotten rid of many of the problems and shortcomings that have plagued it from the very beginning. For example, after recording another disc (even if the recording drive that was used was completely new), it is impossible to say with one hundred percent certainty that all the data was correctly copied to the disk. Another inconvenience of working with optical media is related to the growing volume of information. It has become many times more difficult to navigate which drive to look for a particular program or document on. And finally, the most important “disadvantages” of a laser disc are data loss due to mechanical damage (scratched surface of the disc) or as a result of a recording error. However, so far there is no serious alternative to optical media, so it is necessary to look for ways to solve these problems, at least partially. Utilities with which you can evaluate the condition of disks and recover data from them will be discussed in today’s review.
CDCheck 3.1
Developer: Mitja PerkoDistribution size: 1.5 MB
Spreading: shareware
Interface: Russian It is possible to draw a conclusion about the condition of the disk “by eye” only if obvious mechanical damage is visible on its surface, indicating careless handling of the media. The more scratched and dirty the working side of the disk is, the higher the likelihood of failures when reading data from the media. But even if, after the most thorough inspection, no cracks or scratches are found, this does not indicate that the data from the CDDVD will be read correctly by the device. Recording errors can also occur as a result of a software glitch or due to the failure of the recording device. Many people use a simple way to determine the quality of a recording - the media being tested is inserted into a DVD drive, after which the data from it is copied to the hard drive. The logic of this “test” is simple - if the data is copied, then the optical disk is in perfect order. Actually this is not true. The fact that the data was copied to the hard drive only means that some information was read by the drive, but the very fact that the copying process is completed does not guarantee that the data on the hard drive is completely identical to the data that was written to the media. You should also not rely entirely on comparing the sizes of the original and copied files - even if they match, the data may differ. Comparing data manually is inconvenient, especially when there are a lot of files on the media, so it is best to control the quality of recorded discs using a special utility such as CDCheck. One of the main functions of this utility is to determine the integrity of data on the media. For this purpose, the program generates a checksum for files and folders, a unique code for a particular case, by which one can judge the reliability of a copy of the data.
CDCheck works with different types of checksums - MD2, MD4, MD5, Adler32, CRC32, SHA (1, 256, 348, 512), Tiger (128, 160, 192), etc. Before burning a disc, the program can analyze the contents of the future media on the subject of compatibility of data recorded on CD/DVD with ISO image standards. Data verification can be performed either by checksum or by the “source-copy” principle. At the end of the scan, the program can launch an external anti-virus scanner, checking the content for viruses. CDCheck allows you to set the priority of a job, and also has a data recovery function by repeatedly reading disk sectors. When a certain percentage of reliability is reached, which can be set in the program settings, the data can be considered recovered.
By processing data with CDCheck, you can monitor detailed process statistics: average data reading speed, estimated data processing time, number of scanned files and folders. The utility supports command line operation and provides detailed information about the CD/DVD/BD media used.
DiskInternals CD & DVD Recovery 3.5
Developer: DiskInternals ResearchDistribution size: 3.5 MB
Spreading: shareware
Interface: English A utility for recovering lost information from optical media is one tool from a whole set of various tools for recovering lost data that the developers of DiskInternals Research offer. This program can work with any optical media: from CD-R and DVR-R, to dual-layer discs and DVD-RAM. CD & DVD Recovery detects "missing" files recorded in ISO9660, UDF and Joliet systems. This data can also be recovered if the data was written to the disk in multi-session mode.
The operation of restoring damaged or deleted data is greatly simplified thanks to the step-by-step wizard included in the program. Following his instructions, you need to select the media whose contents are inaccessible, and then specify the parameters of the files to be restored. So, for example, for a more accurate data search result, you should determine the approximate size of the files to be resuscitated, as well as indicate the approximate time of their creation. These criteria are of particular importance when analyzing a disc with multiple recordings, on which there are many “traces” of old information once recorded on this medium. CD & DVD Recovery identifies the location of lost data on a disk and can work with long file names. The program provides access to files from any track, even if the session on the disk was not closed correctly.
CDRoller 8.0
Developer: Digital Atlantic CorpDistribution size: 6 MB
Spreading: shareware
Interface: English The problem of unreadable disks has given rise to a mass of utilities created to solve it. Some programs are designed to test the quality of recording media, others are designed to read surviving information. Typically, this uses a multiple read method, where the program tries to copy the data from the damaged disk as accurately as possible. However, in practice, these utilities cannot always save the situation. For example, if the copied file is large and contains one or more unreadable fragments, then such data may not be suitable for further use.
The simplest example of such a situation is a damaged DVD with a movie recorded on it. As you know, the contents of the DVD-video format usually look like a Video_ts folder, where menu and navigation files are located, as well as large files with the .vob extension, which contain video and sound. If the unreadable area of the disk is in the place where the vob file was recorded, this file will be partially damaged, resulting in a large fragment of the video being lost. It is possible to partially restore the remaining video. Firstly, for this you can use additional tools that can correct errors in the video file code. However, if the damaged area is large, then such utilities will not be able to cope with the recovery. Other programs that can fix a video file will use re-compression, which will inevitably lead to a loss of original quality. The CDRoller utility can solve this problem faster and more efficiently than many other programs. Having copied readable data from such a disk to the hard drive, CDRoller will analyze the vob file and divide it into separate fragments (movie scenes), saving them in the MPEG format familiar to the DVD video standard, without loss of quality. In this case, you can simply exclude the scene with the fragment where the defect is present, and record a new disc with the surviving data.
Thanks to the built-in recording module, the disc burning procedure can be performed directly in CDRoller. The program allows you to burn recovered files and folders, videos, as well as ISO image files.
The disk cataloging tool built into the program uses so-called short images (Short CD/DVD Image). In fact, these are not real images, but only data about the contents of the indexed disk - a list of all files and directories on the disk, with a preserved structure. Each time a new disc is read, the program can automatically create such a short image and write it to a specific folder, thus compiling a library of all discs. In the future, if you need to quickly find a specific file, you can use CDRoller to search the entire library of images. The data search tool is implemented very flexibly; the search query can be refined using various search criteria. For example, you can set the minimum and maximum size of the file being searched, define the subject of the search (for example, only folders, files, or both), specify the creation date, etc. Another feature of CDRoller is the ability to work with audio discs. Despite the relative durability of audio discs, sometimes it only takes one tiny scratch for a CD player to refuse to play a particular track or even recognize the disc. In order to save the recording, the program uses digital data extraction (Digital Audio Extraction). During the audio reading process, CDRoller can use jitter correction and also use sector re-reading to detect errors or loss of synchronization. The read tracks can be immediately converted into various digital audio formats - WAV, MP3, MP2, OGG, etc. The program can encode audio CDs on the fly, without creating an intermediate WAV file. To evaluate the quality of optical media, CDRoller runs a series of tests (the test can be started by selecting the drive from the list of available devices and using a keyboard shortcut), selecting a test method depending on the type of data recorded. The program checks the ISO 9660 file system and also checks the disk surface, after which it displays a detailed generated report on various media properties - the number of detected sessions, the program in which the recording was made, the size of the file allocation table, the list of unreadable folders, etc.
Please note that this check cannot be applied to disks with the UDF file system. Errors on optical media with such a file system are detected automatically. This data recording format is widely used by various models of DVD camcorders, DVD recorders, as well as batch recording applications such as Roxio Drag-To-Disc and Nero InCD. Users who have to deal with such discs often encounter a situation where the captured and recorded video is not played back. Typically, data recording errors occur at the session closing stage. They can be found when working with devices from a variety of manufacturers - Lite-On, Thomson RCA, Philips, Panasonic, etc. In most cases, CDRoller allows you to partially or even completely recover this data.
IsoBuster 2.5
Developer: Smart ProjectsDistribution size: 4.8 MB
Spreading: shareware
Interface: Russian This program is a universal data recovery tool. Many users consider this utility to be the best tool for “fixing” unreadable data from optical disks and, I must say, for good reason. The program is updated regularly, and the long list of its features grows from version to version. At the moment, IsoBuster can resuscitate data from almost any media, including BD and HD DVDs.
The secret of IsoBuster's popularity is, first of all, that this program understands all existing file systems that are used today to record data. The utility works with the contents of images; it can be used to mount images and extract data from them, as well as directly run files. The program supports the formats of all popular disc burning programs, such as CDRWin, CloneCD, DiscJuggler, BlindWrite, WinOnCD, NTI, Plextools and many others. IsoBuster can also be used to create an exact image of the source disk, and the image can be written in .iso, .bin, .tao formats, created with cue markings and a .md5 checksum to determine data integrity.
The program makes it possible to check the status of the media (you don’t even have to extract data to the hard drive) and can create a list of files containing read errors. If the program detects bad sectors when reading a disk image, IsoBuster can collect statistics of bad disk areas and save it to a separate file. If restrictions are imposed on the file system (for example, FAT), the created image files can be divided into parts, the size of which is specified in the IsoBuster settings.
