Unable to reload "safely removed" camera card

[Meteor]

A search for the title didn't bring up anything. I've tried various wordings but cannot get anything positive. Perhaps I'm being too vague or am looking in the wrong place...

I booted with the card from my camera in the slot in my printer (Canon PowerShot A590 and HP PhotoSmart D7360). The card was mounted and I was able to view the photos. After doing so, I simply properly unmounted the card and continued on with a different project. I then needed to remount the camera card and put it in the appropriate slot in the printer expecting it to appear on screen. Nothing happened. The card icon wasn't on screen and not shown in any selection under the "Home" icon nor anywhere else.

Is there a way to get it back without rebooting the system? I'm running Lisa RC 32 bit as a full install (with a few hundred updates (plus 8 "recommended" awaiting). Julia didn't have any qualms about reloading a camera card. Lisa must be requiring me to do something different? If so, what? Am I doing something wrong.

What is it that I need to do that is different so I can work with Lisa?

That forum link was spot on about the use of the "safely remove" option. You don't want to use it in conjunction with card readers. Otherwise, the reader will be disabled until reboot. With that said, on a windows machine, cards used in card readers are hot swapable. They don't need to be safely removed. Is it still necessary to use the "eject" option, in any Linux distro?
