Unstoppable Copier is a free software specialized in recovering files from damaged discs. Both hard drives as CDs/DVDs.

On certain occasions, when trying to copy files from a hard disk or CD, we find that the Operating System informs us that there are read errors on the source disk and that we may not be able to copy the selected files/directories. In these cases, we need a tool that can read the files of the source disc and try to retrieve the information from those files.

Unstoppable Copier is used to recover information from files that can not be read. We must not confuse this program with other data-recovering software that recovers files that have been deleted from the hard drive. This program does not recover files that have been deleted, but it recovers those files that are corrupt, and the Operating System can't read.
A file may be corrupt because the Disk sectors are defective or the CD/DVD has some scratches.

The use of the program is very simple, so we need to choose the origin disk (or directory) and destination. Suppose we are trying to recover data from a hard disk. In that case, we must ensure that the destination of the recovered files is another hard disk different from the origin because the latter may contain bad sectors. Therefore, the recovered files can be corrupted when storing them on that hard disk.
Once we have selected the source and destination, press the button “Copy,” and the recovery process will begin. It will not be necessary to intervene in this process since it is automatic.
During the file recovery process, the program will display a series of stats about the recovery process at the bottom of the window. Some of the data shown in these statistics are; Files copied, Corrupt files, good Bytes copied, corrupted Bytes copied, Read errors, successful Writes, and more.

The program can make batch files recover (batch Mode). This means we can choose multiple drives/folders to retrieve the corrupt files. We will choose one of the drives/folders to recover, and once added to the list, we can start with the recovery process. The program will process and copy the files from the drives/folders one by one.

The program has a series of options that allow us to keep all the information from the original file. These options are: Keep Attributes, Keep Owners and Maintain Time/Date.
Another interesting option is the “File Not Damaged First.” This option allows recovering first those files that are not damaged. This way, during the first minutes of the copying process, files that have a good state will be copied first, and at the end of the process, the files that have some damage will be copied. So if a corrupted file fails, and interrupts the copy process, at least we will have recovered all the files that do not have any default.

We have the possibility of varying the accuracy of the file recovery. Higher precision means a higher time needed to recover defective files and a greater percentage of success in recovering the damaged files. If we want to vary the level of accuracy, we must go to the tab “Options” and move the bar to “Exhaustive Recovery.” This way, we will have the highest percentage of successful recovery. If we move the bar to “Quick Recovery,” the file recovery process will be faster and less accurate.

Despite being free and having a simple look, this software has proven to be one of the best programs to recover corrupted data, offering better results than other paid programs. Without a doubt, essential software for any PC.
