Compact discs have long ceased to be reliable Data Recovery Services storage media. It is generally accepted that discs can remain in usable condition for up to a hundred years. In fact, it turns out differently: disks store files for up to ten years at most. Data Recovery Services from CDs and DVDs depends on the type of damage caused. Each case and symptoms of a corrupted disk are described below.
Types of CD/ DVD damage :
People using “blanks” often have a situation where the outside of the disk does not have any damage, but data cannot be read from it. First you need to check the disk on any other device, because sometimes the problem may be hidden in the incorrect operation of the computer or drive. Data read errors are often corrected by lowering the read speed. Special programs allow you to manually set a fixed low drive speed. This will increase the chance of successfully reading the data.
Another common cause is careless handling of CDs. The surface of the disc smeared with fingerprints leads to reading errors. In this situation, data recovery from CD and DVD will not be difficult. You will need a wet and dry wipe. It is necessary to gently wipe the work surface first with a damp, and then with a dry cloth, avoiding circular motions. If the situation is too advanced and you need an additional disc cleaner, use an alcohol solvent.
In the case of scratches and other mechanical damage, it will not work to get rid of some napkins. The procedure for recovering data from scratched disks requires special software, equipment and certain skills. Scratches on the disc are filled with a special paste and polished. After that, the software causes the drive to read the damaged parts of the disk many times in a row without error messages.
Data recovery from cracked CDs and DVDs is an unjustified risk. The disc can break into pieces at any moment and, even worse, damage the drive. Therefore, service centers with expensive equipment do not often take on such work.
The next type of Linkedin data loss is associated with the software part, and not with external influences. Data loss and read errors are affected by various write failures. Constantly overwriting a CD or DVD-RW disc can lead to logical errors. RW discs have a quick format feature that everyone actively uses. With such an erasure, the information is not completely deleted.
Therefore, you have to restore data piece by piece using special data recovery software . You can try to recover files yourself. There are many free programs on the Internet designed for this purpose. If the disc contains information that is too important for you, it is better to turn to professionals.
