To put this in the simplest terms, the rest of the disk space is reserved for indexing the file system. All operating systems have some means of doing this (for example, the FAT - file allocation table - in microsoft file systems). For the same reason it is possible for a filesystem to be more than 100% full. FreeBSD will sacrifice the space reserved for indexing if it can. Of course, it is usually the case when a filesystem is more than 100% full that something has gone serious wrong. -- Lars Eighner eighner@io.com -finger for geek code- http://www.io.com/~eighner/index.html 8800 N IH35 APT 1191 AUSTIN TX 78753-5266
