[QUOTE=bunanson;252212]Worked on 1st shot

sfdisk /dev/mmcblk0p1 -uM

Error message:
"Checking that no-one is using this disk right now...
BLKRRPART: Invalid argument
OK
Warning: start=1 - this looks like a partition rather than the entire disk. Using fdisk on it is probably meaningless.
(Use the --force option if you really want this)"

Now what?
Thanks
