The boot partition is about 4 G like it should be.

I checked the card with Parted Magic -live cd and it shows that the card has three partitions (one really small) and two aproximately 4 gigas. Where are the two missing gigas when I use the card on 770 (or Windows)?
We will find your 'lost' space together, how about that ?

1) dl and install DiskUsage from maemo.org>download or /gronmayer.com/it/, which give a breakdown of your disk use.

2) xterm
df > /media/mmc1/df1.txt
cat /proc/partitions > /media/mmc1/cp1.txt

Here are my outputs for N810 for comparisons

================================================== ==

For N810:
mmcblk0 internal 'SD' fixed
mmcblk1 external SD
My N810 is drunk, and get infFl and extSD mixed up

/dev/mmcblk0 and /dev/mmcblk1 intSD/extSD p1 FAT
/dev/mmcblk0 p2, p3 debian
N810:
2G intSD = 1.3G Fat + 0.6G debian
8G extSD = 5.9 Fat + 1.9G p2 +.2G p3

For 770:
mmcblk0 SD
1G = .3G Fat + .5G p2 +.1G p3

do you need 4G p2? why?
