I umounted OK, but I can't sfdisk. I get the same "...using fdisk on it is probably meaningless..."
I unchecked virtual memory and it's no longer even checkable.
I have an 810 with an 8GB external card.
I'm running 4.2008.36-5
That explains.
mmcblk0 is internal
mmcblk1 is external
so, my example will get your internal card on the N810 partition, if successful. Is that what you want to do?
A. In most instances this step is unnecessary; so, at least if you don't have a card reader or Windows, skip it and see if the process turns out OK anyway.
B. Download and install the Panasonic SD Memory Card Formatting Software into your Windows computer.
C. Place your SD Card in a card reader.
D. Use the Panasonic formatter to format the card. Select the options for FULL Erase ON and for Format Size Adjustment OFF. (It doesn't matter if the formatter reports that it can't use the Erase function.) This low-level formatting takes about 10 minutes.
so, my example will get your internal card on the N810 partition, if successful. Is that what you want to do?

Yes, but when I run sfdisk /dev/mmcblk0p1 -uM I continually get the following:
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)
I fine-tuned my tablet, threw away some progs that I dont like and made some minor setting changes, and cloned another 4G SD disk by just one command: ./nupgrade.sh wipe. That is the beauty of this, once you did it, the rest use only one command, no more dl, wget etc.
