Defragging Smart Media Cards

My camera is so very old. It's way past time to get a new one. It's an Olympus D-320L from 1997 - older than my daughter. A lot older than her. It uses up to 8MB smart media cards. I've got four of these - 3 in 8 MB and one 2 MB card. I've begun to notice that the camera is erroring out on these cards more often. I'm not sure if it's the camera or the cards. But I take a picture and then I get a rapid tweeping and the display flashes. I have to close the camera and that picture is gone. This happened before, but it would also come back up in low-quality mode.

I talked to David and he suggested defragging the cards, especially since I'm still using a 3.5 floppy adapter to read them. I tried this today and got the following message:

Disk Defragmenter cannot run on this volume type.

So, it looks like it may very soon be time to shop around.
