I am going to use a controller pulled from a external backup drive that had a 2.5" SATA laptop drive in it.
Drive has mini USB connector and a small controller board that plugs into the drive and powers it off of USB the drive had a 250g drive in it but I am going to use it with a 120G drive that came out of a dead Xbox360.
I have seen many sites that have USB to SATA adapters for reasonable prices as well as docks for the same.
I have some of these for full size drives also recovered from external drives and they use a controller board also that plugs into the drive but use external power to meet the needs of the full size drive(usually 12 volts)
If you are more worried about ,spelling, punctuation or grammar you have probably already missed the point so please just move on.
