Mount Rainier (MRW) is a format for writable optical discs which provides the packet writing and defect management. Its goal is the replacement of the floppy disk. It is named after Mount Rainier, a volcano near Seattle, Washington, United States.
Mount Rainier can be used only with drives that explicitly support it (a part of SCSI/MMC and can work over ATAPI), but works with standard CD-R, CD-RW, DVD+/-R and DVD+/-RW media.
The physical format of MRW on the disk is managed by the drive's firmware, which remaps physical drive blocks into a virtual, defect-free space. Thus, the host computer does not see the physical format of the disk, only a sequence of data blocks capable of holding any filesystem.[1]
