Recover Data from Corrupted CD/DVD

Sometimes disk might be unreadable because of problem that took place during the process of burning. For example, the software or device may be unable to finalize the last session on the disc or write the contents only partially because of system crash or power outage. The logical structure of such discs could be incorrect preventing regular software and devices from reading the content partially or fully. However, physically such disks could contain actual data that was supposed to be written to it. Such data (video and audio streams) could be extracted with Recover Disc. Some of its features are listed below:

Recover Data from Scratched and Damaged CD/DVD: If a CD or DVD disc is scratched or damaged, the software can only partially read it or it may be fully unreadable. In such scenarios, Recover Disc can extract the intact portion of the data and even try to recover problem areas. It enables browsing of disc content and select files that one need to rescue. Alternatively it can save an image of the whole damaged disc or each track, if many tracks are present on the disc. The program works under windows 2000/XP/2003/Vista and supports all types of CD and DVD media. Smart error handling and flexible retry options helps one complete the task in minimum time and maximum probability of successful recovery. Sophisticated algorithm used to read the content of the disc makes the program applicable even when the information contained in the file system tables is partially lost.

Support of discs burned with DVD Video Cameras and DVD recorders: Recover disc can work with DVD media created by DVD recorders, Video cameras and other standalone devices. It can help in case the disc is damaged after burning or if it is burned incorrectly because of technical problems with the device.

Retrieve Data form all sessions on multi-session discs: While writing a file to a CD or DVD media one usually has two options. Burn the whole disc at one or write data in several successive sessions. In later case, multi session disc is created. While browsing the content of such disc with regular software, one usually sees files from all sessions and is not divided by sessions anyhow. However, if a newer session contains a new version of a file that was also present in one of the previously burned sessions, one can see the last version. The old one will be physically present on the disc but it will not be accessible. Recover Disc can read resolve the problem. When it encounters several versions of a file in different sessions, one can choose the version to extract. Besides, it has an expert view mode to browse full disc structure with all tracks and sessions. This way one can browse the content of each session separately.

Support of ISO and UDF file systems: Recovery disc supports any CD and DVD discs containing ISO or UDF file systems. UDF system is generally used on discs created with “drag and drop” software which allows working with CD or DVD as usual drive that is copy and change files on it on fly. When Recovery Disc encounters several file systems on the same disc, it selects one automatically. If the disc content information is partially lost in each file system, the programme can merge the remaining data to find as much files as possible. If one is interested in seeing the detailed disc structure, one can switch to expert mode view. In that mode one can browse each file system separately. It is useful if different file systems on the disc actually reference different sets of files.

Merge Partial Data recovered in different environments: Physical parameters such as temperature may also vary during successive reading attempts. Consequently, one may find out that different areas require different environment to read them properly. However, one does not have the option to read the first part of a file on one device and second part of the same file on another one. Recovery Disc provides such possibility. When one extract a file from a disc and some areas cannot be read, the corresponding places in the files are left blank. Later while trying to extract same file, the program will read only the part that was not extracted and merge with it previously extracted data. Ultimately if there is scratch on the disc that makes only a few sectors unreadable, one can try to polish it. However, other data should be extracted to avoid damaging it.
