I have had this just sitting next to my computer for the past few months, and just decided that I don't really need it.
I bought it new, its a 250GB, much more than I will ever need as I do not have much files. I am also tired of it allways buging me to backup the system when there is nothing new.
Anyway, its like new, 250GB Dual interface, which means it has firewire and usb ports. I have all the manuals, CD and cables that came with it. I paid almost $300 for it, and I am asking $150, which includes shipping.
Here is a link from Seagate website.
