Yes I understand what you are saying. The drive bay is larger then the card reader itself so yes there should be a panel that fits in the drive bay that holds the card reader. That's how mine is anyhow. Unfortunately I don't have access to a photo atm.

I think this is it: U592R Flex bay filler assembly
