Perform a surface scan


This option is available from every CD/DVD icon.

After this scan, IsoBuster will inform you of the amount of errors encountered.

Errors on a disc are not necessarily always a problem.  They might be located in areas where there is no useful user data.  E.g. sectors that are 'often' unreadable, depending on the media and the way the tracks were written :

- The last two run-out blocks of a session
- The run-out, link and run-in blocks (7 blocks) between every packet (in case of packet writing)

After the scan, in case there are file-systems with files on the disc, files that are located in erroneous sectors will also be 'marked' with a special icon :  (c) IsoBuster

The list with erroneous files can always be recreated without the necessity to redo the scan.  Just select the File System icon and create the list via "Directory tree and file information".
