500 GB external HD (MyBook Pro) by Western Digital. It has firewire 400, firewire 800, and USB 2 connectivity. It’s still in the box with the wrapper. This is the silver version, not the black. ($185 shipped OBO)
I also have a Toshiba Satellite A135 S4656 Laptop Computer with Windows Vista home edition, an 80 GB HD, Intel Celeron processor, and 512 Ram. I used it for 3 months for writing and emails when my primary computer needed repair. I’ve since restored it to the factory default settings and now would like to get rid of it for some extra cash. I’ve got the power adapter, and two discs with software that came with it. ($300 shipped, OBO).
