I've seen replies to this type of problem with other models that note that solutions are model specific. I no longer have access to my LS400 via its IP address or via the desktop application. I have tried a factory reset with no success. The LED continually flashes white with no breaks or color changes. I tried re-seating the drives. I hear the sound of one drive trying to "search", but that eventually stops. I am not super tech savy, so I'll probably need a relatively simple solution. If there is not one, then I'm off to buy a new one. This is my second Buffalo in ten years. My warranty has expired, so no surprise that the Buffalo support number is locked away from view.
