Paper Abstract

Most operating systems have no fail-safe features built into their file systems. They rely on recovery programs to repair the file systems after failures have occurred. These actions often result in loss of files, and sometimes the files are not recoverable. The loss of data in high capacity storage devices is extremely costly. We illustrate how robust file systems may be built for the WORM optical disks.
