the standard measuring tool is HPL which solves for a very large multidimensional array. Prepackaged rpms might be found in the Rocks distribution. The answer is yes to each of your other questions

FSCK_MSDOS(8)						    BSD System Manager's Manual 					     FSCK_MSDOS(8)

NAME

     fsck_msdos -- DOS/Windows (FAT) file system consistency check

SYNOPSIS

     fsck_msdos -q special ...
     fsck_msdos -p [-f] special ...
     fsck_msdos [-fny] special ...

DESCRIPTION

     The fsck_msdos utility verifies and repairs FAT file systems (more commonly known as DOS file systems).

     The first form of fsck_msdos quickly checks the specified file systems to determine whether they were cleanly unmounted.

     The second form of fsck_msdos preens the specified file systems.  It is normally started by fsck(8) run from /etc/rc.boot during automatic
     reboot, when a FAT file system is detected.  When preening file systems, fsck_msdos will fix common inconsistencies non-interactively.  If
     more serious problems are found, fsck_msdos does not try to fix them, indicates that it was not successful, and exits.

     The third form of fsck_msdos checks the specified file systems and tries to repair all detected inconsistencies, requesting confirmation
     before making any changes.  The default behavior is to always ask for confirmation of each change.  Use the -n or -y options to override this
     default behavior.

     The options are as follows:

	   -q	   Causes fsck_msdos to quickly check whether the volume was unmounted cleanly.  If the volume was unmounted cleanly, then the
		   exit status is 0.  If the volume was not unmounted cleanly, then the exit status will be non-zero.  In either case, a message
		   is printed to standard output describing whether the volume was clean or dirty.

	   -f	   This option is ignored by fsck_msdos and is present only for compatibility with programs that check other file system types for
		   consistency.

	   -n	   Causes fsck_msdos to assume no as the answer to all operator questions, except ``CONTINUE?''.

	   -p	   Preen the specified file systems.

	   -y	   Causes fsck_msdos to assume yes as the answer to all operator questions.

EXIT VALUES

     fsck_msdos exits with a value of 0 when the filesystem is clean (or has been repaired), and 8 otherwise.

SEE ALSO

     fsck(8)

BUGS

     fsck_msdos is still under construction.
