It seems to be a High Sierra issue. If the drive is nit visible in Finder, one cannot eject it. However it will be seen in Dish Utility but still cannot be ejected. If I do not forget, I will disconnect the hub before start up then reconnect it.

Well, it could b that the external media got corrupted because you ejected it before all the data blocks had been written, or it could just be that the computer got confused.

In any case, try real hard to eject your media first. Open finder hit command-shift-C to bring up a list of attached devices and find your external media and hit command-E. Then you need to wait until the device disappears from the list.

Best wishes,

Hi all,

I have been using a new USB hub to connect devices to my computer. While connecting a USB thumb drive, finder only sees the thumb drive until I remove it without ejecting it. After that, finder does not list the drive once it is inserted, but it does give me an error message to eject the drive first before removing it.

It doesn't matter if the drive is inserted directly or through the USB hub, but this seems to happen after the first eject error involving the USB hub.

Why is this happening?

Any help is appreciated.

Antonio
