Well thanks for the post, but I am familiar with these formats, & have read it, but I wanted to know more than that like how to actually make an HFS & NTFS partition, all you have posted is the definitions of the file formats, I wanted to go further, & I have also Googled this as well, & see others have asked this, so I dont think my question was unreasonable. So I guess I will look to mroogle for help.
Not everybody can just choose one or the other formats, I do encounter windows computers still, so I cant just ditch windows formats for all mac formats, & it is all nice & well to install mac drive for windows on my windows computer at home or NTFS 3G on my mac, (which looks a bit complicated, still a mac newbie), but if I find myself needing to plug in my hard drive into a mac or pc that is not mine, I can just go in & try to install Mac drive or NTFS 3G on their computers to read my drive, I need to be able to use it on the spot, hence my question on splitting the drive into NTFS or HFS.
