I haven't got the stuff to build the kit yet, it should be here in a few days, but I have a 1TB Samsung USB SSD that is formatted to NTFS, single volume, with "MusicServer" as the top folder, then Artist>Album>Track. Would I be able to shrink the one volume and add another volume with the format needed for the Pi? Also I read quickly that the Pi drive would need a 3rd volume for something. My memory is not great, so I see this stuff but don't commit it to memory until I am hands on.
Anyway, when get there, can I plug the SSD into my Windows computer and use a partition software to shrink the existing NTFS partition and make the other two with different formats?
