I have been looking into bricked Hitachi drives and it seems they can't open or close like mine can't in the xbox 360 but in jungleflasher it can if it opens and closes in jungleflasher does that mean it is not bricked for more info

I am trying to flash a Hitachi 47 but it doesn't seem to work when I insert the drive into the xbox 360 i can't eject the drive and the message on the xbox when a disk isn't even in the drive is 'unplayable disk' this is all a bit confusing as jungleflasher says its been flashed with 1.51 check the link to see.http://yfrog.com/0c87844030p also i can eject the drive in jungleflasher but the ck3 pro will not why is that?
I'm not sure what I've done wrong any assistance would be very helpful as I need to give it back on Saturday and it isn't working!
