hi i have a bunch of iso files that i want to write on a single usb hard drive. for example i want to burn my MS office 2010 and adobe CS5 (has 3 discs). so what i do is make partitions for each giving them enough space to be written on. but when i write to the usb hdd it reformats everything and removes all the partition.
how do i write to usb without breaking the partition tables. also how do i choose which partition it uses. as on the drop down menu it only says the whole usb hdd.
