Digital BW, The Print

I was using a Dane-elec 1 gig compact card in an Olympus E20. I
took several exposures during the day...checking them as i went
along and all seemed fine. I tried to copy the exposures using a
card reader and nothing was being transfered from the card to my
computer. The drive that the card was on showed nothing. I put the
card back into the camera and the camera program stated that I was
trying to use an unfomatted card. I knew that I would loose the
exposures that i had made but i reformatted the card anyway. After
reformatting in the camera, the program told me that the card was
full. I knew that wasnt the case. I do know that the camera was
functioning properly as i put in another card and was successfull
using the same card reader and copying to the computer.
Has anyone else had the same experience. I imagine that the card is
fried.
Any assistence would be greatly appreciated
