Shipping floppy drives - Disk in or out?

When floppy drives were new, they usually came with that cardboard piece inserted, and with the drive door closed. When shipping a floppy drive, is it really best to have something closed in the drive? I'm talking about single head 5 1/4" drives here. I've seen several methods: Nothing inserted, drive open nothing inserted, drive closed Disk inserted, drive closed cardboard protector, drive closed disk, in sleeve, inserted *sideways*, drive open (can't close it like that) disk inserted backwards, drive closed. Now, on a single head full height drive, there really isn't a whole lot to damage. The sping on the lever mechanism is pretty strong, so it's unlikely that it'll slam down and hit the head unless it's really dropped hard. And, if it does, it's just got a fuzzy pressure pad there - not another head. Also, with something as thin as a disk inserted, does it really protect anything? I suppose that the closed position is more stable, since then the mechanism would be fairly solid, and you'd have less chance of damaging the drive door, but would that mean any shock would press on the head? A similar question would probably be - when single head full height drives were new, did they ship with a cardboard protector? I primarily only remember those from the half height and double sided drives. And only once have I seen one for a 3 1/2" drive (it was basically a solid plastic disk). And I also remember getting some new high density 5 1/4" drives that were not shipped with a protector. -Ian
