Windows Explorer supports the Eject command for removable media devices.
If you use the Eject command on a library, Removable Storage Manager (RSM) may no longer be able to move media in the RSM media library.
RSM must be used to manage media in a library (multiple removable media device).
If you used Windows Explorer to Eject media in one of these devices, replace the media and do a Full Inventory of the library:
1. In RSM, expand the Physical Locations folder.
2. Right-click the library and press Properties.
3. Change the inventory method to Full.
4. Press OK.
5. Right-click the library and press Inventory.
