exactly like this one: OWC mercury on-the-go it's a 30gb toshiba 2.5" hard drive taken from my g4 ibook bought last september. 4200 rpm. works fine, nothing special. it will come with the black case and a firewire cord. it's powered by the fw port, so no power adapter needed. paypal fine. feedback on ebay under "kuginomura". please PM me if you have any questions. oh, it also has a white apple sticker on top of the case. can remove if you want. asking sold! in USA.
