I'm thinking of getting one of the Hitachi 7K60 7200RPM IDE notebook drives to replace the rapidly-filling-up stock 20GB drive in my 15" TiBook. In addition I want to get an external FW/USB enclosure to put the existing 20GB drive in for backups, etc. , so I'm interested in specifically: * if people recommend getting an enclosure that offers external power (via AC transformer, or I've heard there are some that can draw power from a USB port)? I've seen some threads about bus-powered enclosures and people blowing out their FW ports and/or the controller on the enclosure itself, is this a problem people have seen with 2.5" enclosures? * If there are enclosures that offer FW800, or is FW400 all that's offered on 2.5" enclosures? * Brand names of enclosures people have used and liked. Spent many months lurking here, great site & great info!
