Sometimes the method you use works, sometimes it doesn't. That's the chance you take.
The PROPER way, is to right click on the slot, select Import, then when it unlocks the 'mailbox' (that's the small door) you put the tape in there and BE will move it to the proper slot. Then you inventory it.
Right now, BE is probably saying: There's a tape in this slot. I have no idea where it came from or how it got here. So I'm calling it "Unknown Media".
I suggest taking the tapes out and properly importing them.
