Thanks! This seems to have worked very well!
I just installed the software, and was able to write to my external HDD immediately. Nothing else to set up (e.g. reformatting drive).
To test it out, I just copied some files over to my external HDD (eHDD), and then mounted the eHDD to my bootcamp partition being virtualized by Fusion. I was able to read over on that side without a problem.
Now my question is whether or not have can have both my bootcamp partition and my MacHD recognize the eHDD without having to dismount/unplug/replug the eHDD? i.e. Can I set it up so that when I plug in my eHDD, it mounts on both the windows side (virtualized in vmware) and the mac side?
