Persistent 'Disk not ejected properly' error on iMac

This is a multiple times a day error message received on my desktop "Disk Not Ejected Properly" when I haven't ejected the Disk and when I do eject the disk properly. Apples support has already tried to help me by running a Disk Utility First Aid which took over 48 hours to complete. Should I schedule an appointment with Genius Bar to look at this? I have two external Hard

drives that were on my previous Mac desktop.
