Rather that calculating md5sum sums on your files, why not use diff -q this is much more efficient as it can stop reading in the files as soon as it finds a byte different (or if the file sizes are not equal it can report that they vary without reading a thing).

mincdiff
MINCDIFF(1) MINC User's Guide MINCDIFF(1)
NAME
mincdiff - report differences between minc files
SYNOPSIS
mincdiff [-header|-body] [-l] [diff options] file1 file2
DESCRIPTION
The mincdiff shell script compares two minc files by running diff(1) on the headers of the two minc files, and cmp(1) on the image vari-
able. You can view only the header differences using -header or only the body (image variable) differences using -body. The option -l is
passed on to cmp of the image variable. Any unrecognized options (e.g. -u) are passed verbatim to the diff of the headers.
OPTIONS
-header Compare only the headers of the two files.
-body Compare only the image data of the two files.
-l Print the byte offset in decimal and the byte value in octal
for each difference encountered in the image variable.
