Ok, I'm planning on getting an external harddrive and from what I've read the Seagate 200GB USB/firewire drive seems to be a pretty good choice. It seems though most of the reviews I've read were all from Windows users, and I am curious if anyone here has used one w/ a mac and has any thoughts on it? Also Im curious about the 1 touch backup button feature. I won't be using this as Ill be using it to manually store and retrieve files, so is there a way to disable this so I don't accidently hit it and it starts backing up? or does it say ask you to confirm on screen before a backup like that begins? Thanks.
