CDRoller - Applying Scan UDF Disc

In addition to another methods of CD/DVD/BD data recovery, Scan UDF Disc gives you a good chance to retrieve several types of files, including:

·	Files are not visible in Windows Explorer - the writing process was interrupted by a system or power failure before UDF folders were placed on the disc, but most or all of the files were written to the disk. This means that the files may be on the CD (DVD, BD), but Windows Explorer cannot see them.

·	Lost files - complete files that do not have a file name associated with them. They can also be files that you accidently deleted from the CD (DVD, BD).

·	Files on the disks quick-formatted by Roxio DirectCD and Nero InCD.

·	Files located in unreadable (damaged) UDF folders, including the root one.

·	Files located on Sony Mavica CD finalized with failure on the camera. Forced scan is recommended.

·	M2TS files on the discs that were not finalized by AVCHD camcorders. Forced scan is recommended.

To start Scan UDF Disc select the same option in the Tools menu or in the Side Bar. The program displays a progress dialog similar to the one shown here.

After UDF scan is completed or canceled, found files and/or folders are displayed in the Lost objects detected on disc... window similar to the one shown here

You can rename the selected folders, open them with the help of Open command, or left double clicking on their names. If the lost folders have been found, try to open them first. This may give you a chance to recover the files with original names that are located in the found folders.

When applying the Recover All / Recover Selected commands, the program automatically identifies the types of files, initially shown as FileXXXX ones, or the files having an intermediate extensions, such as .ole2 for MS Office ones.

If you know an original type, you can rename the selected files manually, with the help of Rename command, or/and use New Extension option to speed up the re-naming process in case of the large list.

If you're going to retrieve UDF files from the same disc at the different times, you can save the table of contents (names,locations, attributes) of the found files into separate file by Save Table Of Contents command from the File menu. Further, check on the Load Table Of Contents from file box on the UDF Reader tab in the Preferences dialog. Next time, when you will run Scan UDF Disc the program will display the list of the found objects shortly, without scanning the disc, and you can continue to retrieve the files data.

If the program can not recognize UDF disk, but you are certainly sure the disk contains the files, we recommend you to try the forced scan of the disk. This may be useful if the disk was incorrectly finalized, and the system data are not accessible. For example, this problem often occures on Sony Mavica CD when the finalization step failed on the camera.

To start the forced scan, you should initially know what CD/DVD mastering program (or device) formatted your disk. For example: Roxio (Adaptec) DirectCD, Nero InCD, PacketCD or Sony Mavica CD digital camera. Further, you should assign an appropriate profile in the Forced scan list under the UDF Reader tab in the Preferences dialog and click the Refresh button in the Tool Bar.

Obviously, there is no 100% guarantee to recover all displayed files completely, please keep in mind, that some files may be erased or partially re-written by a new ones. The program can restore those FILES DATA, which else it is possible to rescue.
