Dan here.

If you would not mind a little assistance.
I'm trying to dual boot from an A-Data 16gb sdhc card and I've done it successfully with Transcend cards in the past. I'm trying to spilt the card by partitioning 10gb for internal and 6gb for external. last time with Transcend I did 5gb internal and 11gb external successfully.

I keep getting after doing sfdisk:
"The command to re-read the partition table failed Reboot your system now, before using mkfs."
"If you created or changed a Dos partition, /dev/foo7, say, then use dd(1) to zero the first 512 bytes: dd if=/dev/foo7 bs=512 count=1
( See fdisk(8).)"


can you write out the no-reread command line or the sfdisk command line for me or refer me to where I can read up on this for n800. Google only brings up non n800 ways.

I have used Panasonic low level reformat successfully.

It goes through the entire nupgrade.sh steps successfully. I end up with only one partition, external with 5gb and no internal. Also I do: " umount /dev/mmcblk0p1 " Before command line " sfdisk /dev/mmcblk0 -uM ". I've also out of frustration tried: " umount /media/mmc2 ". When I originally did this process after the three( ,,, ) commas command the total storage copacity when would be correct. Now the total storage capacity is off by about 500mb after: " /dev/mmcblk0p2: ,,, ".

Update: I tried with another card, so I know it's not the card. I reflash and did the whole process again and still end up with only 5gb on external. Very frustrated.

Any help or guidance will be greatly appreciated.

Thanks,

Dan
