I wouldn't say everyone, Alex, but the probability's are greater than 
one. And so far one is all there is that we have heard about... I've 2, 
1 gig scsi drives on mine, one running at a cluster size of 4, and one 
fully nitros9 running a cluster size of 16. and have had zero such 
problems. That makes my finger point at a flaky wear leveling algorythm 
in that particular u-sd card.  I'd try another from a different era and 
src in that case just to prove/disprove the theory.

I know zip about FUZIX, so that its acting like an ext2 filesystem could 
figure in, but the bottom line would have to be IDK. I am not one to say 
it can't happen, Murphy lives too close and his hearing is perfect.
