The present FreeBSD msdosfs code has problems with some DOS filesystem configurations. From the experience of others, it seems that a FIPS- modified partition is more likely to cause DOS filesystem access from FreeBSD to fail. The results are not entirely predictable, but may include corruption of part of the fixed disk data. Fortunately, if the FreeBSD msdosfs doesn't like the DOS filesystem in question, this tends to be obvious right away. (If that's any consolation.) The msdosfs is in the process of being rewritten. Putting aside potential FreeBSD problems, FIPS itself really relies on a kind of trick to achieve its purpose. And problems can arise if anything should happen to the boot sector of a FIPS-ed partition. Under these circumstances, MS-DOS may silently resort to _deriving_ the filesystem configuration values, rather than getting them from the boot sector. The result may well be the sort of mess that any respectable filesystem repair utility will only aggravate. FIPS does have its place, though, and can be used as a tool to 'bootstrap' a partition split. For example: Use FIPS to split DOS partition C: DOS format the newly-created partition as D: Zip the entire contents of C: to D: Re-fdisk and re-format C: Unzip D: to C: Of course, the best advice is to make a backup of the existing data and repartition the disk from scratch. If the backup is retained for a day or two, it should by then be clear whether the new setup is going to work. -- Robert Nordier
