A:AnswerI was able to connect my 1 TB external drive. I could copy files from that drive to my Mac mini. However, I could not write to the drive because the format of the drive is Windows NT File System NTFS. It is read only. I was unable to change that. I am able to read and write to standard USB sticks.
A:AnswerIf nothing is plugged into the hub and the blue light is on it either means that power is left in it after the laptop is shut off or it means that it is drawing a small amount of power.
A:AnswerThis is simply for Type A ports, it does not have a HDMI plug in, you should find another hub such as the "Hyper - 7-Port Universal USB-C Hub - USB-C Docking Station for Laptops - Space Gray" as long as you have a USB-c port that can transfer data and power.
