I am using two of the 10 TB G-drive. I changed my MAC to 2020 iMAC several days ago. Since they, G-drive crashes unexpectedly. I tried: (1) turn on only one of the 10 TB G-drives, (2) restarted iMAC, and (3) restarted G-drive. Still, G-drive crashes. Are there any known problems? My older G-drive crashed before, and the problem was its cable then. I purchased these two 10 TB G-drive this spring, and I did not have any problems with my older MAC laptop or iMAC.
