I am starting to get random ejection of external hard drives over FW800 or USB. I see that others are having this issue with Mavericks. It doesn't seem to be specific to hubs or direct connections.
This is on a new MacPro and Mavericks 10.9.2, and a Belkin TBolt express dock.
Has anyone seen this and found a workaround? I am trying to copy a 500GB project to a portable drive for a remote edit tomorrow and I'm getting nervous I won't be able to get things ready for the client.
