Apologies for resurrecting an older thread but as regards formatting tools I use BiNG. Although not freeware, there is a trial period. Furthermore (and similarly to PM which I also use), it can be run from a bootable CD with no installation, which is the way I like to run any partition manager utility. BiNG will detect hard drives connected via USB2 and will allow formats, resizing, etc. My use of PM was superseded to an extent by BiNG simply because I was under the impression that PM8 (which I understand Norton has now dropped from its line up) could only handle max partition sizes of 320GB. On previous PM versions that I used eg PM6 there was also a size limitation officially of 40-50gb but would work to 80gb. Beyond the safe limits PM would just crash the partition on any attempt to create or resize.. I too have external USB drives formatted to FAT32 my largest is 500gb (465GiB) and works fine. Not sure if I feel confident having a larger partition than that. As an aside (and I am sure that a lot of you are well aware of this) one can also use GParted as a (free) partition manager (create, resize, etc) this prog can either be downloaded as a standalone utility or can be run from a Linux Live CD (I particularly like Puppy Linux, which I also have installed on a dual boot system). GParted is quick efficient and as safe as BiNG. Good Luck
