What Andrew says about connecting your drives directly to the Mac instead of the dock. Unplug and reconnect your dock.

Quote:
I’ve really only use disk utilities to reconfigure a flash drive to work on my MacBook Pro to use for DJing.


Explain further.

Try the following:

Shut down. Hold the Command r keys down while booting. You should be in the Repair Partition on booting. Go to Install Mac OS. It should offer to download and reinstall High Sierra.This will not affect your data.

If you cannot enter the Repair Partition, let us know.
