I've installed several of those "FreeAgent" external drives now, as
additional storage for DVRs that don't have room for more internal
drives. They install easily and work well, as Frank says, and they're
dirt cheap - CDN$100 for a 250GB. At that price, you could have two or
three and cycle them through for backup duties, keeping one offsite if
so desired.
