Squall, how on earth did you gain this "knowledge"?
You're 18, you've probably just finished high school...
Ever seen Cookie's age? 28, yeah, he probably had a tad more education I guess....
furthermore, WDZ works with server systems a lot. on servers, It is VERY important that no data loss ever occurs, so I'm pretty sure he knows what he's talking about...
I don't know where the hell you found out about your "facts", but please keep in the back of your mind that half the internet still screams msgplus contains spyware...
EDIT:
As for the topic

You should look at how you're gonna use the disk.
If you will just be using it for the current system (Windows XP), I highly recommend that you use NTFS.
However, if you're planning to sometimes bring it along to friends (a friend of me sometimes takes his HDD with him to transfer some not-so-legal files), I suggest you stick with FAT32, simply because not everyone has XP yet, and Windows 98/ME can not access NTFS filesystems
