For some time, my answer to disappearing memory has been to always unplug the USB device before removing (or inserting different) memory cards. The issue is that they seem to not signal the USB infrastructure that they have been ejected, and thus the operating system doesn't know. In fact, most "x in 1" card readers --- ones that read many types of memory --- actually attach a bunch of disks with zero blocks in addition to attaching the memory card you have inserted --- as if they have the capability of simutaneously handling all different kinds of memory (although they often don't). So this seems like an acceptable solution. Until now. Now that I have a Dell 2405 flat panel display on my desk (gorgeous, BTW), I have a permanently attached cluster of memory card slots. Sure ... I can grope around behind things, find the usb cord for the monitor, but that's very ungraceful and ends up unplugging any other USB devices that go through the monitor (thus causing all kinds of trouble). So I set about tonight to see if I could convince camcontrol to realize that one of the previously full disks was now empty again. It doesn't seem that I can. Maybe what we need is 'usbcontrol' ... allowing us to reset (or at least reset the OSs idea of) one usb device.
