    Try this. Plug in the card to a good ubuntu and see if it puts up 
anything like a good card will do. If nothing go to /media and see what 
the mount point is. It should be like KINGSTON or such.

    Now click on the image for the stick and unmount it. Now in a 
terminal type:

$ sudo mkfs.ext3 /media/Stickname 

This should put a good ext3 file system on your SD.
