Can an eSATA port on an external drive enclosure be connected via an adaptor to a USB2 port on the desk top computer? My external drive is no longer being recognized by the computer through a USB2 cable even after plugging it into different USB2 ports on the computer. I replaced the external drive and it still is not being recognized. I have an eSATA port on the external drive enclosure but none on the computer. I'm hoping the eSATA port connection on the external enclosure is still connected to the drive itself internally.
