What is "mount rainier"

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 disks is a layer placed in between the file system (e.g. UDF or FAT32) imposed by the operating system or the packet writing software used to write or read the disk and the physical layer which determines how data is written to or extracted from the optical disc. This is transparently managed internally by drive's firmware which remaps physical drive blocks into a virtual and defect-free space. Therefore, the host computer does not see the physical format of the disk, only a sequence of data blocks capable of holding any filesystem.

Mount Rainier (pronounced: ), Mount Tacoma, or Mount Tahoma is the highest mountain of the Cascade Range of the Pacific Northwest, and the highest mountain in the U.S. state of Washington. It is a large active stratovolcano located south-southeast of Seattle. It is the most topographically prominent mountain in the contiguous United States and the Cascade Volcanic Arc, with a summit elevation of .

Mt. Rainier is considered one of the most dangerous volcanoes in the world, and it is on the Decade Volcano list. Because of its large amount of glacial ice, Mt. Rainier could potentially produce massive lahars that could threaten the entire Puyallup River valley, and poses a grave threat to sections of Seattle, a city of over 650,000 people with more than 3.7 million living in its metropolitan area.
