Packet writing is an Optical Disc Recording Technology used to allow writeable CD-ROM and DVD-ROM media to be used in a similar manner to a Floppy Disk . Packet writing allows the user to access the contents of a CD-R or CD-RW disc directly through a mounted filesystem (Unix, Linux, or Mac OS/X) or drive letter (Windows). Without packet writing software, one would have to use regular CD recording software to ''burn'' a whole disc. Packet writing can be used both with once-writeable media such as CD-R , DVD+R and DVD-R , and also with rewriteable media such as CD-RW , DVD+RW and DVD-RW . Once-writeable media cannot however recover space once used; A deleted file does not free space on the disk, and a modified or overwritten file occupies additional space even if the file size has not increased. When the free space on a once-writeable disk is exhausted, no further update to the disk is possible. Rewriteable media, on the other hand, can be updated and reformatted many times just like a floppy disk, limited only by the eventual failure of the media. Several competing and incompatible packet writing disk formats have been developed, notably those of Adaptec DirectCD and Nero AG InCD . Proposed standards include Universal Disk Format and its proposed extension Mount Rainier . This is further complicated by the fact that is nearly impossible to unformat a disc formatted specifically for packet writing thus rending it unusable in computers that do not have support for the proprietary mode.
