Hey, I've just tried this on my Mac running OS X 10.3.7 and it works fine. The only thing to consider is that if you write files from your Mac to your Hi-MD the Mac will create a .Trashes directory which isn't visible from the Mac (files that start with a "." aren't visible by default). If you use your Mac to delete files they will be copied into the .Trashes directory (actually a sub-directory of this) so the file will look like it has been deleted but your disk space won't be freed up until you empty the trash folder. The Mac will also create very small ._yourfilename files in addition to the files you copy on (I think this is because files on the Mac have two forks, resource and data, one of which is your file the other can hold custom information like icons and preferences). Actually I am making it sound a lot more complex than it is, the best thing to try is to copy files from your Mac to your Hi-MD then take a look on your PC which will show all the files that the Mac hides from you.
