I've a external 500 Gb HDD that I've used Disk Utility to format it as MS-DOS file system (FAT32) that I would like to define as a HDD in Parallels. When I try to add a HDD using the configuration editor I get the options to add yet another virtual disk or to "use boot camp". I'm using Parallels because I don't want to use boot camp. The Help documentation is no help ... What am I missing? Edit: Oh, forgot. Build 4560. This build runs the video editing software I want and the later builds have problems with video drivers (and it will not run).
