I have confirmed that all the USB ports on my laptop are working . Well I purchased a hard drive enclosure. I place the hard drive inside an nothing happened. I think this hard drive is dead. Now I am out the money I paid for this piece of crap seagate freeagent pro. a called around to see how much it would cost to recover the data. It will cost any where from $700 to $2500. I will never buy another seagate product again.
