Mine came already formatted as NTFS, but I decided that since I was backing up a linux system, I'd just feel better if I used ext3, so I reformatted it to that for no particular technical reason :-). Note that you can get to NTFS from linux by installing ntfs-3g and ext2/3 from windows by installing Ext2IFS (http://www.fs-driver.org/), so either filesystem can work for windows or for linux.
