Have a client, they use QB 2009 Server Manager on their SBS 2011 server. They use Macrium Reflect for backup and they have an offsite USB drive they swap every friday. For some reason the USB drive will not eject when they go to swap the drive out. As soon as i kill the QB Server Manager, the drive will eject. I made sure the Server Manager is not monitoring the drive, but it is still holding the drive, keeping it busy so it won't eject.
