USB3 external drives randomly ejecting
Since the 10.12.5 update, I have been experiencing random ejects of external USB3 drives.
This is occurring on a 2011 21" iMac (12,1)
Normally I have 2 of USB3 Segate powered external drives connected via a Belkin Thunderbolt 2 Express Dock and have had this setup running for a long time without any issues.
I have tested the drives connected directly to the computers USB2 ports and they continue to randomly eject.
I have connected the same drives to my late 2013 15" MBP (11,3) both directly and via the same Thunderbolt Dock with no issues.
I have also connected the same drives to the USB port of my Airport Express and they stay connected without any issues as well.
Has anyone else experienced a similar issue since the latest update or any suggestions in searching Console logs for example as to where I may expect to find any relevant error messages that may indicate whay these drives are being ejected?
Thanks in advance
