A common goof is for a root user to mistype a device name causing a
file to be created in /dev/ containing the data which was written. Tar
will happily create such a file.
Another goof is for root to "write" to an unmounted filesystem. Later
when the filesystem is mounted the written files are hidden yet still
consume space on the fs containing the mount point (usually /).
If the results from "du -xsk /" and "df -k /" are not real close then I
suspect you have written files in a directory which was later used as a
