I am getting this error when I try to eject usb drive from my server. I use it for data backup. I copied some file and then in My Computer when I try to eject it, the usb stucked on the error. It is not coming out. I closed all the files and applications. I can only remove by log off. Does there is some application in the service that engages the external storages. I can stop that to fix the problem. Thanks.
