Mac Mini randomly ejects all USB disks after I plug in a new USB disk
I have a Mac Mini (mid 2001) with 2 external hard drives connected via USB.
Sometimes, when I plug in a new USB drive (thumb or hard drive) on any USB port of my Thunderbolt Display, all external hard drives are ejected, all but the new one.
After some seconds they are reconnected automatically.
Mac mini, OS X Mavericks (10.9.2), Thunderbolt Display
