I have a new travel USB hard drive that I will be using on the road with my Macbook Air, mostly for storing the data/work files of many different programs. I've been reading up on some of the formatting options for the drive in order for Mac and Windows to both be able to read and write to it. The options seem well laid out in this article. So it seems to me that the only option is to have some sort of software, weather on the mac or PC, to be the communicator between the OS and the formatting that it can't natively read. A lot of my software is windows only and I'll be using it in bootcamp on my Mac, but I prefer to use Adobe Lightroom on the mac side. So my question is, will any of the software's mentioned in the article above allow my programs on the opposite OS (opposite to the travel drive's formatting) to read and write on the drive, or does everything have to be moved around within the software's GUI mentioned in the article? (for example: If I go with the NTFS formatting and use the software that allows the mac OS to read it, will Lightroom (installed on the mac side) be able to read all the data, photos, settings, etc. that I will work from and store on the new travel drive (formatted to NTFS)?
