Another thought: If you've played with these cards a lot; had them in a 
card reader, etc. I might suggest getting rid of any cruft in the first 
few blocks:

dd if=/dev/zero of=/dev/yourrawcarddevice bs=1024 count=256

On any sort of Unix box will do the trick.    (the values above aren't 
critical, just good enough to get rid of any garbage)
