Unfortunately, the Drive is a custom drive. Instead of a SATA interface, the SATA port is replaced with a USB port directly. What you can do is remove the plastic enclosure to see if the USB port is loose or partially separated from the drives logic board. If it is, you may be able to fix it by soldering it back in place or with a new USB port.
Other than that, if the drive is failing mechanically, I would suggest copying as much as you can at a time to a replacement back up drive.
