I'm unable to eject USB drives. When I try, I get this error:
The disk "Untitled" wasn't ejected because one or more programs may be using it.
To eject the disk immediately, click the Force Eject button.
Additionally, when I use Disk Utility to erase a USB drive I get this error:
Disk Erase failed with the error:
Couldn't unmount disk.
This happens on my account and my wife's account. I can partition USB drives, but I can't erase or eject them.
Any ideas on how to resolve this?
