When I connected the card directly to the pc w/ the adapter, it saw it as a 6gb drive and I could copy things to it (or move files over from memory when in the 8300).
Solution: Take the card out and put it in the usb adapter and reformat it (fat32) on your computer to 6gb. Try it again in the unit. It showed up through explorer and the Roxio software and can now use it while still in the device. I've found in the past that any memory cards (of whatever type) give you less problems if you reformat them first on your computer.
Yes, this has been reiterated on these forums, however the experience that we all seem to be observing is that once you actually put more than 1.7 GB of data on the 6GB card it will become unusable from the device.
