In case anyone is interested, here is a small patch to make hfsutils work with large volumes (over 4Gb).
Under Linux, I also has to compile the code with
"-D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE"
(There is probably a way to do this via 'configure', but I haven't a clue how to do that ...)
The only strange bit about the the patch is that I had to split the "return" line into two lines - which is the only way it would gives the correct result using gcc v2.96-98 on Linux for large numbers ...
