Does Labview RT 8.5 impose a limit on FAT32 partition / hard disk size?

Question

We will be using a PXI RT system (spec below) to collect, analyse and store a
large amount of data (~30 to 40GB per experiment).
We don't want to keep the Windows host PXI attached
and so the RT PXI must be able to store all the data from an
experiment.
It would be desirable to keep data from all
experiments on the H/D, so a capacity of ~300GB would be useful.
Q: Is there a limit on the hard disk size imposed by the Labview RT 8.5 Operating System and if so what is
it?
An older
post (~2005) suggests that the partitioning tool limited FAT32 partitions to 32GB.
Thus the question I'm asking that if I created a large FAT32 partition with
a third party tool could I install and run Labview RT
8.5?
Q: Is there any other way of connecting a
large capacity H/D to the RT System?  For example using H/D partitions, slave H/D. Other
ideas?
Thanks,
Michael

> The size limitation has nothing to do with
the LabVIEW RT OS. FAT32 limits you to 32GB. This cannot be changed since it's a
limitation of the file system format.
Thanks for
reply.
I have, however, gained the impression from a
number of web sites that there isn't a 32GB partition limit on FAT32 -- see [**]
below -- but the limit is with the
partitioning tool.  It looks like the
partitioning tool that comes with RT has a 32GB limit (Is that correct?). Hence
my question if you were able to create a large FAT32 partition could you install
and run RT?

[**] The following was copied from http://en.wikipedia.org/wiki/File_Allocation_Table#FAT32
Windows 2000 and Windows XP can read and write to
FAT32 file systems of any size, but the format program included in Windows 2000
and higher can only create FAT32 file systems of 32 GiB or less. ... This
limitation can be bypassed by using third-party formatting
utilities.
