i did say presumably. can’t see someone formatting to linux filesystem if needed for windows at some point, since if needed on another windows box then this needs to be installed. if it needs to be used on windows as well then i’d go for ntfs, wouldn’t format to ext2/3 then install this. but that’s me, maybe this user is different than me.
post above sounds rude i know, but it isn’t meant to i promise 
i know there are drivers for windows to allow read/write access to linux FS drives, which i can understand need for for internal drives, but external… well a little less perhaps.
