To rad the disk at all, you will require a 3rd party application. Look here for some suggestions:

I like MacDrive a lot...great product.
Once you can read the mac formatted disks, you should be able to copy the files to your system. From there, launch the appropriate program (ie. Freehand) and then go to File > Open and select teh document. Another possibility (though it will not always work) is to rename the file with the appropriate extension on the PC. For example if you had "cooldrawing" as a file, you may rename it "cooldrawing.fh5" to open it with Freehand 5.
Good luck...hope this helps!
