So I have an external hard drive I use for backup, of both the Mac and Windows sides of my computer. It's split into an HFS+ and a NTFS partition. However, after I run backup on the Windows side, the HFS+ side becomes unreadable and needs reformatted. 


I've read that this is because Windows writes some extra stuff to other partitions with the most space, and it reads HFS+ as empty, so therefore writes to it. So if it were a separate HDD but in the same enclosure/likely through the same cable, would this still happen you think? Or should I just have two completely separate external drives?

You will need two separate drives. I am not sure what you mean, "through the same cable". You cannot have two separate drives simultaneously running off the same data cable. You would have to alternate swapping a single cable between two drives (disconnecting from the alternate drive). If that is what you mean, yes, that would be fine. It sounds like the easiest thing to do is use a docking station and swap drives as you do your backups. Or possibly this one with dual bays, then all you would do is switch between the bays, no need to swap out drives.
