I used my scan disk 2.0 GB on another computer and the computer gave me a message "USB Device not recognized. Device may have malfunctioned." Now when I insert my scan disk, I receive this message on every computer I use. My office tech guy told me that the other computer fried by flash drive but there may be a way to retrieve my files on my scan disk. Are there recovery programs? Where can I find them and how much do they cost?
