FATTY: A Reliable FAT File System

Most portable digital devices use the conventional FAT file system because of its compatibility. However, the FAT file system is unreliable across system crashes and power failures. This paper proposes the delayed sequential write method to improve the FAT file system 's reliability. Compared to other methods such as synchronous write and logging, the DSW method is simple and effective. Simulation results show that it is also quite efficient, about 50-80% better than synchronous write.
