It is a USB3 version and I've tried in in USB2 ports but I never get a 
chance to read anything, the "media not present" error triggers as soon 
as it's plugged in. I'm trying to decide if the data on it is worth 300 
USD (which was the cheapest recovery quote I could find) to me. If 
anyone has suggestions for a person or company that will do it for $200 
or less suggestions are welcome :/
