this may seem strange to ask but i recently purchased a 1 TB drive and formatted it correctly to use it as a time machine archve. after a few HOURS my 160 gig mac primary disk was backed up. i then created a second folder entitled "not time machine backups" and am copying my iphoto library etc to it. i plan on using that drive to store my photos from now on. it this ok? can i use this so called "time machine" drive as a second hdd? i figure as long as i dont actually touch the time machine folder, i should be ok, right? thanks for clarification.
