As you know, the life of the optical disc is not long, the disc can stop reading due to various reasons – if a faulty hard drive recovery have scratches, physical wear and poor-quality material to make the disc, etc. Data on this disk cannot be read and copied by the operating system, although files and folders on it are displayed in Goodwill in Windows Explorer.
It is clear that there is a need to worry about the presence of quantities to think about such situations before and in time. Backup But in practice, this often does not happen, because many users did not do this until the end users finally postponed the reservation to “later” (in secret hope that everything would be fine).
And finally, at one point, they are confronted with the fact that images, video clips, music clips, and sometimes important documents and distributions are completely inaccessible to them. At the same time, it is possible that data can still be read using special utilities.
The fact is that the OS, if it cannot read the information correctly from the damaged part of the disk, then copy and delete the already copied part of the file. And special utilities, using other mechanisms to read data, can eventually read such files and copy them (although they do not guarantee 100% recovery of all files).
These utilities read information from direct access to the CD / DVD-ROM drive, bypassing the standard Windows tool, they take several attempts to read the damaged disk part, and thus after any reading errors that are often used in your original form The information in the eclipse disk allows “bridge” to continue to read / copy information.
If this number is not passed, then most of these programs, with no solution, change the unreadable areas with zero – it is natural that there is some defect in this file at the end. It is clear that in practice all files cannot be restored in such a way that it will be suitable for further use.
For example, in the case of text documents after such a recovery, a couple of paragraphs will disappear, but it is certain that it is better to complete the loss of an important document made for the entire month.
As everyone can do quite decent in terms of audio and video data – Obviously, if at any point to listen to your favorite tunes or to preview a movie, you can hear a strange sound again Or on the screen you will see a strange phantoms, but again, it will be better to lose treasured content, it is better with the software, but trying to restore the data Is still understandable, because malicious bad zones can appear on some helpful files, which you do not need at all.
