it is possible in general, but I don't know your specific drive or what enclosures fit it. There is a site that does this kind of thing, but I don't recall the name right now. Someone else should help us out...
Usually you just take your drive, the enclosure, and put them together. The enclosure has a firewire port and then it's just like a firewire drive. A lot of CD-RW manufacturers do this--they take a mechanism developed by someone else and smack it together with their own particular enclosure. A little more involved than that, but you get the idea.
