Both Bringfried and Wayne are working under Linux, so the file-size
limitation of FAT32 is not likely to be the issue here, not unless the
system is ancient. Given the 64 bit nature of the beast I doubt that.
The file-size limit should be 2^63 bytes.

I think the right answer was given by Wayne is his original post. What
I don't get is why you'd want a 4G unformatted data file in the first
place, I'd prefer to dump the data to an HDF-5 file.
