FSUTIL outputs a NULL character (not a space) after every drive specifier, this can cause difficulty when piping the output of fsutil into other commands (particularly FOR). The output from FSUTIL varies by OS see this forum thread for more detail.
Some features in fsutil are reported to not work correctly under FAT or FAT32 volumes e.g. FSUTIL dirty query.
