SYMPTOMS

When you try to eject the media in a removable media drive by using the Eject option on the context menu of Windows NT Explorer, the following error occurs:

An error was encountered trying to unmount Removable disk [D:] Check to make sure there are no open files or windows from that volume.
In addition to the conditions mentioned in the error message, this error will occur if the user does not have Administrator privileges on the local computer.

CAUSE

This is by design.

RESOLUTION

The user must be given Administrative privileges, to use the Eject functionality of Windows NT Explorer.

MORE INFORMATION

An Iomega Zip drive is an example of a device that will demonstrate this behavior. Other comparable devices are thought to function similarly.

The media can be ejected manually through the release button, but the Eject option on the shortcut menu that appears when you right-click Windows NT Explorer will not work if the user does not have Administrative privileges.
