Sony Mavica MVC-FD71 Floppy Drive Camera with 10x Zoom

Not sure if the floppy  drive works,  Ive tested with a spare disk but says "No Disk" when inserted.  

Not sure If I need to do anything else or if the reader is faulty (or my floppy disk is faulty (its old) ) 

No Charger included (needs standard Sony Camcorder battery type chargers).

Includes Genuine Sony NP-F330 Lithium Battery
