When you start Backdraft Conform, a volume integrity check is performed automatically if a previous crash is detected. This check determines if there are any inconsistencies between the clip metadata stored on the system disk and the frames on the framestore and, when possible, repairs any problems that are found. Inconsistencies can occur if the application crashes before the metadata associated with a clip has been saved to the clip library on the system disk. Metadata for clips on the EditDesk is saved by the autosave process, while metadata for clips in the clip library is saved following various operations such as opening a new clip library.
