Thanks for your answer. Let me try to be clearer:
I want to use the 4TB My Book Duo with my new iMac. The iMac has a 1TB HDD–and I plan to partition it so 800GB is the MAC OS and 200GB is for a Windows installation.
My basic question is how best to setup the My Book Duo so (1) I can use it for automatic MAC backups using Time Capsule; (2) and use part of it for Network storage of files accessible by MAC & Windows.
Out of the box, I _ can _ re-format the whole NTFS drive for the MAC using HFS+ – or partition the drive and format one partition as HFS+ and the other as FAT32 or exFAT.
If I do that, I need to understand whether this configuration affects my ability to set up a RAID configuration.
