An MS-DOS File System for UNIX Alessandro Forin Gerald R. Martin September 1993 CMU-CS-93-196 School of Computer Science Carnegie Mellon University Pittsburgh, Pennsylvania 15213 <A shorter version of this document appeared in the 1994 Winter "Procedings of USENIX" and is available from ftp.sage.usenix.org> Obtain from CMU techincal papers archive for CS department or from CMU via WWW. My opinions: This paper indicates a number of ways that can be adapted to generally speeding up a DOS file system. On the other hand, it has an agenda against UFS that is pretty crystal-clear in the way that they approached UFS: disabling the cache and using very small disks, disabling clustering, etc. In other words, believe the DOS speedup portions of this paper but do *NOT* believe the UFS slowdown portion of the paper; it is rather too slanted, IMO, but useful for DOS FS work if you can ignore the slant.
