I recently purchased n Ultra CompactFlash Card up 30 MB/s* 200x for my Canon Camera. Have been using it, and just recently when I was viewing/copying images via a card reader plugged into a usb port on my computer, it would suddenly “blank” out, show just the drive letter and say "no images available. I would close the drive and replug it back in, and the images would be there. This happened several times this evening.
How do I tell if it is a problem with the card, reader, or my computer? The pictures are taking just fine, and I’ve not experienced any other problems with my computer so far. How do I resolve this?
Thanks,
Carol
