After you format a disc by using the Windows Vista Live File System, the available space on the disc is less than the capacity of the disc. For example, after you format a 700 megabyte (MB)-disc, less than 700 MB is available for use on the disc.
This issue occurs because the Windows Vista Live File System reserves a small amount of disc space to accommodate link-loss area. Live File System uses Restricted Overwrite mode. In this mode, the media requires a special low-level format. This format reserves a small amount of disc space for link-loss area. The Universal Disk Format (UDF) file system reserves at least 10 percent of the reported capacity of the disc for sparing. Also, if the disc was originally formatted by a third-party program, additional space may be reserved by the third-party program.
