OK, so what I'm trying to do is... I have a MBP with three harddrive partitions. One partition has Mac OS X on it, the other is NTFS WinXP, and the third is a FAT32 data partition.

I want to be able to reference a file on the third partition from BOTH operating systems... but I'm unsure of how to do it because the way the two OS's refer to the drives is different. For example, in OS X, my file might be called:

Where as in Windows, I would define the location of the file as:

So I end up with the problem of my "program" only seeing the file in one OS and not the other, depending on how I define the location. Is there a way around this? Possibly with environment variable or something in the offending OS? Any input would be great thanks!
