The administrator who allocated a CD-ROM at a particular label deallocates it using the Device Allocation Manager. Typically, the Device Allocation is still running in the workspace where it was invoked.
In the role that allocated the CD-ROM, return to the workspace that is running the Device Allocation Manager.
Double-click the name of the CD-ROM device in the Allocated Devices list and move it to the Available Devices list.
Remove the CD-ROM, and click OK in the CD-ROM Deallocation dialog.
To close the Device Allocation window, click the top left button and select Close.
