Mount Rainier is a standard that provides background formatting and defect management for storage on CD-RW and DVD+RW. This makes rewritable discs easier to use and allows the replacement of the floppy. On Mount Rainier CD-RW and DVD+RW drives you can drag-and-dropfiles to the RW disc and the real formatting of the disc is done in the background (invisible to the user). Also, if there are scratches on the disc the drive will recognize this and will replace the bad areas.
Also called Mount Rainier Writing (MRW).
