G-Mini unresponsive

I recently swapped a new iMac (OS 10.14.2) for an old one, and my G Drive Mini won’t mount – it just does this rasping click sound like the disk is spinning but rubbing on something. I have 4 Minis and at least two of them are doing this. Seems like the new computer is throwing the old Minis for a loop! Any suggestions? I’m not a skilled computer person, so please keep it slow and simple…:slight_smile:
