ENDQUOTE The 63 offset is spurious. I've seen this before somewhere but can't remember the details -- i.e the value 63. I wonder whether editing the label and setting both offsets to 0 might solve the problem. You could always make a copy of the existing lab= el=20 and put it back if the changes don't help. You could in addition check the size for the partitions against the size = given by=20 fdisk for the slice. Malcolm Kay
