I don't think so.

The card reader reports that the card contains only about 1 GB, not 2 GB. As I understand it, the standards for SD cards holding more than 1 GB are in flux. There are combinations of cards and readers which simply don't work. This looks like one of them. What happens if you use the same card and reader under another operating system?
