Hi
I have a My Book Studio 4TB external hard drive that I have been using for the last 6 months on my Mac very successfully but it is formatted purely for Mac. I would also from time to time like to be able to copy things from it to a Windows PC but at the moment I have to copy it from the My Studio Book via my Mac to a memory stick that I can then put into the Windows PC to get it back off again!!! 
I’ve tried in the past to look at various formats I can use that would work on both platforms, but I have yet to find one that will work on both AND recognise it as a 4TB drive without it needing to be partitioned. I also have a smaller partition on it already that I use for my Time Machine backups so don’t really want to then partition the remaining section just so it can be read on both Windows and Mac.
Does anyone know of a format that will work for all please?
Many thanks
