I have 1tb external drive that connects to my media server in my kids room. One day the XBMCBUNTU(xenial) running on the media server decided it no longer wanted to communicate with that drive. It does not even show up with 'fdisk -l', however, if I unplug it from the media center and plug into my MAC running PARAGON EXTFS I can see the partition and the kids movies and play them without a problem.
Is there anything that I could use to make the drive show up in fdisk so that I can mount it? or is there a config file that controls how drives are enumerated that maybe got corrupted or something? or is there something that can diagnose problems with my MBR?
