Hello.
Not so long ago, I had to recover some photos from a flash drive that was accidentally formatted. This is not an easy task, and while it was possible to recover most of the files, I had to get acquainted with almost all popular programs to recover information.
In this article, I would like to give a list of these programs (by the way, all of them can be classified as universal, because they can recover files both with hard drives, and from other media, for example, from a memory card - SD, or a USB flash drive).
It turned out not a small list of 22 programs ( further in the article, all programs are sorted alphabetically).

That's all. In one of the following articles, I will supplement the article with the results of practical tests, which programs managed to recover information. Have a great weekend and don't forget backup so you don't have to rebuild anything...
You will need
- -A computer;
- - disks;
- - several drives;
- -SuperCopy program;
- -BadCopy program;
- -program Nero;
- -Alcohol program;
- - cleaning wipes;
- - freezer.
Instruction
A disc is a fragile thing to become unreadable, it only needs a couple of scratches. First, make sure that your drive can actually read the detected disk. optical media information is in the form of CD-ROM, CD-RW, CD-R, or DVD-ROM, DVD-RW. All these formats are different, the drive must match the media. Check the available disks on other hardware.
If the drive is shown but on a PC, try the following:
- use special programs. For example, SuperCopy, BadCopy. Please note that basically this software can only skip damaged areas. This helps if you are trying to recover a disc with movies or music, it will not work with games.
- Polish the disc with a silk or cotton cloth. Make sure there are no new scratches. Make movements starting from the center, smoothly moving to the edges, but not along.
- wipe the disc with a special cloth. Anti-static wipes are available from computer stores.
Place the disc in the freezer for thirty minutes. Wrap it in a bag so that moisture does not collect. This is why it helps: the heating of a cooled disk takes longer, the drive has time to read the information. The main thing is not to overexpose the disc in the freezer, the disc will become more fragile and may break.
Create a disk image using programs such as Alcohol or Nero, copy files already from the image. The virtual system will force disks one should treat the information more carefully. Try it from a disc using Slow CD, Nero Drive Speed. Discs can be read on different speeds, these programs serve to determine the speed.
Wipe the disc with a soft cloth and detergent. This helps if the disc is very patchy. Remember, you can not wipe the discs with acetone, gasoline. After such a wet cleaning, the disc must be completely dry.
Wipe a dry disc with a cloth soaked in vegetable oil. Oil does not conduct electricity, it is not as liquid as water, and it will also remain in a scratch. Even corrupted data can be recovered.

note
Try inserting the CD into another drive, it happens that one drive reads information, the other does not.
Use a combination of all disk recovery methods.
Perhaps everyone who stores any information on disks, sooner or later they encounter such a problem when the computer cannot open them due to numerous scratches and other damage. Often, such discs are immediately sent to the trash can, but do not rush, you can try to recover the lost information and rewrite it to another medium. There are a few easy ways to help you do this.
You will need
- - damaged disk;
- - cotton or silk fabric;
- - special antiseptic wipes;
- - a soft cloth and detergent.
Instruction
First of all, check if your drive can even open and read the detected disk. If not, then you should not immediately panic, check this disk on another computer. Next, check the media for damage in the form of scratches. If a disc is cracked, chipped, or otherwise severely damaged, do not attempt to open it on your computer. Otherwise, due to the speed of unwinding, it may simply crack in the drive, and you will have another problem in the form of fragments, which then will need to be removed from the drive.
If the computer detects the disc, but does not open it, try using special programs such as BadCopy or SuperCopy. But keep in mind that they can only skip damaged parts of the disk. This property will help you to restore audio and video files. As for games, this method is ineffective here.
Try buffing the media with a cotton or silk cloth. This should be done in the direction from the center of the disk to its edges, but in no case in a circle. Try to do everything very carefully so as not to damage the disk even more. Instead of a cloth, you can use special antistatic wipes that are sold at any computer store.
Another few unusual way- put the damaged disc in the freezer for half an hour, after wrapping it in a plastic bag, which will prevent the ingress of harmful moisture. The media cooled in this way will take longer to heat up and during this time the drive will have time to read all the information you need from it. However, be careful not to overexpose the disc in the refrigerator, otherwise it will become brittle, which will subsequently lead to breakage.
To open an unreadable disc, wipe it with a soft cloth and mild detergent. This will help clear the disc of fingerprints or smudges. After this procedure, wait until the disc is completely dry.

Reading, recovering and copying data from a damaged one is one of the most common tasks when working with removable media. The number of proposed solutions is huge, but when trying to systematize, they all come down to a limited set of action algorithms.
Instruction
Try using a soft cloth (silk or cotton) to polish disk. It is not recommended to use circular movements, movements from the center to the edges are considered correct.
Wipe the drive with a special anti-static cloth and insert it into another drive (if possible).
Put the damaged dick in the freezer for 30 minutes, after wrapping it in a bag. Repeated attempts to read a damaged sector lead to heating disk, which causes a change in the refractive index. A cooled drive is less susceptible to heat, which can help resolve the issue.
Try using software (SuperCopy, BadCopy) to replace bad sector values with zeros or try to create an image disk using specialized applications (Alcohol, Ahead Nero).
Use utilities like Nero Drive Speed or Slow CD to change (slow down) the reading speed disk or download specialized program Non-Stop Copy, which does not require installation and is freely distributed on the Internet.
Unzip and run the Non-Stop Copy application.
Perform a quick copy of the damaged disk. At the same time, unreadable sectors disk are marked as broken without stopping the copying process.
Proceed to the refinement process, during which the program determines the exact boundaries of the unreadable sector of the damaged disk or select the fine detail option if there are several damaged sets.
Complete the repair procedure for the damaged disk performing the procedure of copying bad sectors. By default, the application makes five attempts to copy each corrupted fragment.
Use the option to restore the entire directory containing one or more bad sectors using the specialized nscopyd.bat script included in the Non-Stop Copy program.
Call the main menu of the operating system by pressing the "Start" button and go to the "Run" item.
Enter the value "name_ disk:Program Files
scopy
scopyd.bat" "name_ disk:folder_to_copy" "name_ disk:path_to_the_copy_save_location" and confirm the command by pressing the OK button.

The situation where you cannot play the CD normally disk or copy data from it, is familiar to many users. It is especially unpleasant if some unique files are recorded on the disk - for example, a photo archive. Unreadable disk you can try to restore.
You will need
- - soft cloth;
- - toothpaste;
- - information recovery programs;
Instruction
Most often, the readability of information is affected by scratches on the disc and various dirt. Cheap disks are most prone to failure, they low price due to the low quality protective coating. If the disc is no longer readable or you cannot read all the information, carefully inspect its working surface. Remove any dirt with a soft cloth lightly dampened with water.
To repair shallow scratches, use a simple method that gives good results. Apply to a damp cloth toothpaste and polish the damaged area. There are subtleties here: it is necessary to polish across the scratches. Most often, scratches go along the recorded tracks, so you need to polish with movements from the center of the disc to the edges. If the disc is badly scratched, this job can take up to half an hour. Then rinse off the paste, rinse the disc, dry it, wipe it with a soft cloth and try to reproduce it.
If the disc is still unreadable or if you don't feel like polishing it, use special utilities. One of the best in this regard is the AnyReader program, you can find download links on the Internet. After downloading the program, install it and run it. In the program window that opens, recovery options will be indicated, usually the first one is needed - “Copying files from damaged media”. Select this item and click the "Next" button.
The program will open the disk, mark in the list with birds the files that you need to save, and click "Next" again. In the new window, specify the folder where the recovered files will be saved. Click next. The file will start copying. After its completion, the report that appears will indicate whether it was possible to copy the file completely.
You can also use other utilities to recover data: Max Data Recovery, File Salvage, NSCopy. Nice results gives the IsoBuster program, which allows you to pull information from the most problematic disks. Its disadvantage lies in slow work. This program it is convenient to run at night - by morning the disk image will be created.

Almost always, in order to maintain privacy when entering passwords, the corresponding programs display unreadable characters - “asterisks” instead of the characters entered. However, if you see these very asterisks in the password entry field, this does not mean that the password. Often such stars do not hide anything, but wear clean information function- let you know that when you type password will be hidden from prying eyes.
Instruction
Reject the asterisk intent in web pages received from the server. In the vast majority of cases, passwords are not transmitted by the server to the user's browser. You can verify this by opening the source code of the page received by your web browser - it will not contain a password in any way. open form, nor encrypted. Passwords are transmitted over the Internet in only one direction - from the browser to the server.
Use some specialized application program that can read passwords in open windows of other programs. There are no such tools as part of the service components of the operating system. It would be strange if a decryption program were included in the same package as programs that provide password security. the desired program easy to find on the Internet - for example, it can be Pass Checker. The program consists of six files (including the help file) with a total weight of only 296 kilobytes and does not require installation. Immediately files to your hard drive or removable media it can be launched by double-clicking the Password.exe file.
Open the program whose stars you are interested in. Then place the Pass Checker window over the open program and with the left mouse button drag the skull image onto the field with the hidden asterisks password. This field will be highlighted with a flashing frame, and in the Pass Checker window, opposite the window text inscription, the decoder will place password in its unencrypted form. This password you can copy and use as you wish.
Click the Help button on the bottom row of buttons if you want to use more difficult ways password decryption. In addition to the simplest one described in the previous step, the program provides two more options. Despite the English-language interface, the Pass Checker help is written in the language, so there will be no problems.

It happens that important documents, dear photos, videos and other information stored on a DVD-ROM, is not available for reading or viewing. There may be several reasons for this: for example, your disk is physically worn out, made of poor quality material, or scratched. And read or copy the necessary files from damaged disk does not work, even though they are displayed in the operating system explorer.
Instruction
Take advantage of special programs that directly, without using standard Windows tools, read information from DVDs. These utilities repeatedly try to read the damaged part of the disk, continuing this process even after reading errors occur, and as a result “pull” the information in its original form. And if it doesn’t work out, then many of these programs simply change the unread sectors to zeros (although some defect may appear in this place in the document). Of course, you most likely will not achieve an ideal recovery, but it is still better than losing data forever.
Download, for example, CDCheck. This is one of the popular and simple programs. Examining the DVDs in detail, she discovers corrupted files and restores them. To ensure the operation of the program, select the appropriate document, and then click on the "Check" button and specify the folder where you want to copy the information.
Damaged or lost data from unreadable (poorly readable) discs can be recovered using the BadCopy Pro utility. By choosing desired mode(it depends on whether the file is displayed in operating system, but it is not readable, or the data in Windows Explorer is invisible at all), click on the "Next" button, and the process will start. True, it will take a lot of time, because the information will have to be restored separately in each folder.
Another program - IsoBuster - will help you recover lost data stored on a broken DVD. To do this, run the utility and insert a disk into the drive, after which its layout will appear in the panel on the left, and files on the right. If it was not possible to find them, you need to run the search command for missing files and folders.

If necessary, you can cancel both copying one file, and all at once. For this there are special settings. If the utility detects any bad sectors, then the user is prompted to select the operation to be performed - you can try to read the section again, or simply skip it. The choice can be automated by choosing the appropriate program settings.
DVD-type media is very outdated today. However, they are used quite often. It is very easy to damage these discs, but if necessary, even heavily scratched media can be read using special applications.
> Installing CD-R/RW drives is now almost a system requirement for home computer. A variety of software for recording and processing data, relatively low cost discs of both types in relation to the amount of stored information makes the use of CD-R/RW for storing and distributing digital information almost uncontested in relation to other media. The purpose of this article is to familiarize users with programs and possible methods for recovering information, access to which could be lost either as a result of mechanical damage to the disk, or as a result of erroneous actions user. The following programs fell under the consideration of the author of the article: CD-R Diagnostic, CDCheck and Isobuster Pro. We will consider the work of each of them on the example of a specific defect.Scratch on the disc in the working area
To assess the capabilities of each of the programs, a really damaged mp3-collection of the Kalinov Most group with a partially unreadable track of one of the songs was selected.CD-R Diagnostic
The first program I trusted to restore the track was CD-R Diagnostic, the demo version of which I was familiar with a year ago, and hoped that this particular program in its full version would be the best.
Although I knew exactly which track was to be restored, I decided to start from the very beginning - with a complete check of the disk for errors.
To check the contents of the disk for errors in the Tools menu, select the Error Summary item. After that, the program will offer us a choice of three types of scanning,
differing from each other in the number of sectors to be checked for readability and the possibility of recovery in case of an error in reading. Quick scan in Help is not recommended due to the small number (about 500) of randomly scanned sectors. It is also not recommended to check the recorded disc in the drive in which the recording was made.
I chose Complete scan and timed it. According to Help, the time for a full scan should have taken 20 minutes, and during this time I wanted to repeat the features of the program through Help. But during the scan, the program did not allow me to press the help button. In fact, the scan took almost half the time. The scan results were:
- without specifying the place of errors. In order to find out the specific location of the errors, it was necessary to deal with the default settings. It turns out that the default is "Do not write errors to file". We find these settings in the menu command File / Preferences ... and put the necessary checkmark:
You have to start all over again. Upon completion of the scanning process, error data is finally available in the form text file opened by Notepad.
There are only errors in this file. Let's start the recovery process. To do this, by the usual click on the song title right button mouse call the command Copy file
Having reached the first sector with unreadable data, the program will ask what to do next
When choosing Accept All program in automatic mode will continue copying the file with the correction of unreadable data, the algorithm of which, apparently, is to fill unreadable places with zeros. Recovery lasted about half an hour, after which it became possible to listen to the saved file. The program in the process of recovery worked in background, at the end of the restoration, I could not call up the window with the program, although the program button was in the taskbar. Moreover, it was even in the Task Manager, but I could not close it through it either. At the same time, the second copy of the program was launched. Can this be attributed to the glitches of the CD-R Diagnostic under WinXP? May be...
CDCheck
The second program that restored this file was the program CDCheck.
We immediately note the presence of a multilingual interface. We start working on the errors again with a full test of the disk. We note to ourselves that in addition to the progress bar, the name of the file being tested is displayed, and when found broken file its name with the error code is displayed in the lower window. At the end of the test, the following message is displayed:
Although the information is not as detailed as in the previous case, you cannot deny the convenience of the interface to this program. Let's now start restoring the file.
Unlike the first program, recovery options are customizable. In addition, the author of the program explains that if the sector is completely unreadable, this place will be filled with zeros. Leave the recovery options set to default and start the process. Again, we note a visual representation of the ongoing process and more complete information about errors and their correction (some unreadable sectors were completely restored, and it took 53 attempts to read it to restore one of the sectors - this surprised me a little, since I thought that under the number repetitions until the sector is marked unreadable and must be understood total number reading attempts. It turns out that in the case when the sector has been read at least once, the program stubbornly wants to read this sector a second time. Therefore, I recommend setting the minimum number of repeated readings of the sector to one). To the convenience of the program, you can add the Pause button. But the most important advantage of this program is that it works with any devices in the system. Unfortunately, it does not access files bypassing the file system; it cannot access disks directly. Therefore, she will not be able to take part in the restoration of erased files.
As we remember, when work CD-R Diagnostic could not call the help file with the corresponding button, CDCheck allows you to do this.
The total file recovery time was almost 1 hour 35 minutes.
IsoBuster Pro 1.2
The third program that took part in the recovery of the file was IsoBuster Pro 1.2.
As in previous programs, I decided to start with a full disk test. To do this, the authors propose the Find missing UDF Files and Folders command in the right-click menu:
The program scanned quite quickly a part of the disk that did not contain errors, but when it entered the area with errors, the matter stalled. Although there is a Cancel button in the scan window,
clicking on it only resulted in the appearance of an hourglass at the cursor location if the latter was in this frame, and the words Not Responding appeared on the blue bar after the words Scanning for lost UDF data. Moreover, at that moment both Hyper Snap-DX versions 4 and 5 did not work either. When you clicked on the program close icon, the system replied that
Again, I don’t know if this is a bug or a specificity of the program under XP. In addition, when trying to drag the window while scanning and copying a file across the Desktop, it turned white. Having interrupted, thus, the protracted (or maybe frozen) scanning process, I decided to immediately proceed to restore the readability of the file. Having selected it in the file table, right-click again to call up the menu and assign "Extract"...
After assigning the path of the copy file, the extraction of the file from the disk begins. Having reached the damaged area, the program asks us the question: "What to do next?"
Mindful of how the scanning process ended, I decided to check the Skip All box (assuming that we are talking only about bad sectors) and clicked on the Skip button. My assumption turned out to be correct - judging by the behavior of the disk and the percentage of completed work, the program made several attempts to read the sector and moved on, and again there were difficulties with Hyper Snap - it was impossible to take a screenshot. Another oddity was that you could run another copy of the program and, judging by the drive coming to life, it even began to recognize it. The total file extraction time was about two hours.
results
In order to find out whether the quantity has grown into quality, we will use Sound Forge 6.0.
The diagrams refer to the same fragment of the file. The top one refers to a copy of the file restored by CDCheck, the middle one is CD-R Diagnostic, and the bottom one is IsoBuster Pro. Comments, in my opinion, are unnecessary. I will stop at one more moment. To do this, we will use WinAmp 2.80 (WinAmp 3.0, for some unknown reason, refused to play the file created by CDCheck).
Part of the file info of the original and files created by CD-R Diagnostic and IsoBuster
And here is the file info copy of the file according to CDCheck
Here is what it looks like under WinHex 10.6 SR2
Above is a code snippet of the copy of the file created by CDCheck, below - the original and the copy of the file created by CD-R Diagnostic.
Which program should be preferred? In my opinion, CDCheck should be preferred in this situation, and IsoBuster is useless in this case. Regarding CD-R Diagnostic, we can say the following, the program, in general, is good (perhaps in its more advanced version of CD-R / DVD Diagnostic it is devoid of some of its oddities in default settings), and in case of simultaneous damage to both TOC and the files themselves, it may well cope with the recovery. I even tried to simulate this situation - a CD-RW disc subjected to quick format with simultaneous mechanical damage. Here is this disk in the picture (the ink was subsequently washed off :))
Recovery of erroneously deleted information from a CD-RW disc
This test involved disks formatted with the program Ahead InCD 3.51.91.
Different types of information were recorded on the disks. Then one of the disks underwent a quick format, and the files were deleted from the other by system tools. I will not separate these two cases, since there is no difference between them. When performing both of these actions, only the information in the file allocation table is overwritten, the files themselves remain intact.
I immediately draw the attention of inexperienced readers to the fact that although the system promises in the form of a hint to easily and naturally restore files deleted from the RW disk from the recycle bin, this is actually not the case. Since only one file allocation table is formed when writing a CD-R/RW, in order to restore access to data, direct access to the disk is required, bypassing the file system. Let me remind you that CDCheck does not have such an opportunity, but another program, already mentioned, will come to replace it - WinHex 10.6 SR-2
And one more note. Since the work of each of the programs in this case comes with the need for exclusive ownership of disk resources, then the disk being restored must fit in a regular drive (or with InCD uninstalled).
CD-R Diagnostic
Again, let's start with CD-R Diagnostic. Immediately upon launching the program and selecting a drive, the analysis of the disk begins, after which the contents of the disk will open before us. Like the first time, intuitive actions lead to an error
We change the window, again we try to set the Copy ...
And again we get an error message...
We open another folder, and, finally, we see the recently deleted files with our own hands.
Although Help "e says that possibly damaged files are marked with a question mark, we try to extract a file that is suspiciously similar in size to the NVIDIA driver installer. After copying to favorite place and renaming it from Unnamed_0018 to 41.09.exe, run it and get the long-awaited
After carefully studying the contents of each folder on both drives, we come to the conclusion that in order not to have problems with renaming files after a possible need to restore them, it is better to use nested folders. In this case, everything happens automatically.
After copying the selected folder (the disk has undergone a quick format), we get
winhex
Let's see now what help WinHex can give us (well-made, with many useful utilities, hex editor). It includes a Disk Editor utility that provides direct access to the contents of any disk
Let's try using it to restore some file, the beginning and end of which are visible naked eye. For this purpose, a book page saved in html format is suitable.
Having selected this block, we save a copy of it as a file
and open it in Internet Explorer:
It is clear that this technique will work for any type of file, the main thing is to find its start and end identifiers. To some extent, the developers of the program have facilitated our efforts by fixing some of them in the configurable parameters of the File Recovery by Type command
IsoBuster Pro
But the IsoBuster Pro program left the most pleasant impression. After getting acquainted with its capabilities, I was also delighted, as two years ago when I got acquainted with the ZipMagic 4.0 program, which launched applications from archives without unpacking them.
So in the case of IsoBuster Pro - the program can not only copy, but also run files from disks that have undergone either Quick Format or Quick Erase. Here she is undisputed leader. Add to this that she can work with DVDs, as well as with disk images, including, she was able to create an image of the disk that took part in this test after Quick Format without data loss (WinHex worked with this image for greater convenience ).
I will refrain from any conclusions on each of the programs, their version numbers speak for themselves. Let's hope that older releases will get rid of the current shortcomings and add in their functionality. You can download demo versions of the programs at the following addresses (current at the time of publication)

Restoring access to information on quick erased CD-RWs
For the convenience of working with CD-RW discs in a number of recording programs, including Ahead Nero Burning ROM , the Quick Erase command is provided, while only the TOC area (file allocation table) is completely overwritten, while the information itself remains untouched. Let's see how easy it is to access this information. Immediately after Quick Erase, both in the Explorer window and in any program that works with disks, this disk will be indicated as empty (blank). Searching Yandex for Recovery Quick Erase CD-RW/ Recovery Quick Erase CD-RW was not particularly effective. The only information that allows us to evaluate the possibility of such a recovery was on remsoft.newmail.ru.A discussion of the situation with the recovery of an erased CD-RW in one of the forums finally clarified the situation with the method of recovering an erased CD-RW, and why it is possible.
Let's burn two folders under Ahead Nero Burning ROM on a previously completely erased CD-RW: the first is the examples for the VB.NET package, the second is the source materials for writing the first two parts of this article (the recording mode is not important, in any case, the files can be fully restored).
And erase the disk by selecting
I already wrote that of the programs I have reviewed that help restore access to information, only CD-R Diagnostic is able to restore access to information while damaging both the TOC and the files themselves. We have the files themselves, let's try to create, albeit damaged, TOC. To do this, we will use remsoft's advice and write an unfinished DAO session (disk-at-once) to a quick-erased CD-RW, while one of the saved Nero projects can be used as the file to be written.
If you rushed to interrupt the session, the system will say that the disk is empty - in this case, it helps to re-burn the disc being recovered in the same mode.
On my experimental "blank" only about 150 MB were written before erasing, so I did not want to take an image of the entire disk (especially since there was unformatted space behind these 150 MB, and how IsoBuster would react to this, correcting this error, I already knew after all the experiments, when I decided to try recovery in it - when entering an unformatted zone, IsoBuster estimated the completion time of more than 1500 minutes, again it hung up and I could only unload it through the device manager).
Since for WinHex the unformatted space was an insurmountable obstacle (it was necessary to replace scrolling with direct addressing to the sector of interest to us)
Its end is easy to find. In the case of sequential placement of files with the same extension, immediately after the end of the allocated section, we will get the beginning of the next file to be restored.
Copy it to a new file and get business card CD-R Diagnostic, which helped us this time as well.
Other files are restored in the same way.
Further, I recorded the same folders on a disk formatted for InCD. Although with InCD installed, a batch-formatted CD-RW disc cannot in principle be erased using Ahead Nero Burning ROM - the latter will not start, under other programs installed in the system, this is possible. For example, famous program Alcohol allows this, and InCD will not even try to prevent this and will determine that the disk has undergone Quick Erase only when the disk is reloaded. As in the first case, we use CD-R Diagnostic to copy the contents of the disk to HDD and re-open it for viewing and editing in WinHex. We see that in the case of a disk formatted for InCD, there is a problem in the form of readable service marks and reserved empty space.
Attempt two - additional removal of places that occur in some places, consisting of only spaces
We can't say that it got worse - pay attention to the correct color of the part of the frame with the inscription Sound Forge. In general, when recovering large graphic files(the size of the file with this picture is over 2 MB) it will take a lot of manual labor and patience.
