During a low-level format, defect lists are populated, which store a list of bad sectors, which are then mapped and a sector slipping algorithm is utilized.When using sector slipping for bad sectors, disk access time is not largely affected.
The FDI format is publicly documented, [5] and accompanied by open source access tools. Because the format can store raw low-level data, as is for example required to support copy protection schemes and other non-standard formats, FDI files can be larger than disk image files in other formats.
