I apologize but it’s a little hard to read your post. It sounds like you may have done a firmware update on the drive? If not, what type of update are you referring to? It sounds like the firmware update failed on the unit. You may need to replace the unit. I would try running the firmware again and possibly try updating the firmware on a Windows based computer. Windows and Mac communicate with drives differently and Windows may be able update the firmware when the Mac is not detecting it.
