hi,
I tried out marble so sulus command gives me an awful lot of files.
I tried his command before I started marble, just didn't save the result but it looked fine (apart from the size of the partition)

Hmm:

Nokia-N900:~# sfdisk -l

Disk /dev/mmcblk1: 121008 cylinders, 4 heads, 16 sectors/track
Warning: The partition table looks like it was made
for C/H/S=*/49/48 (instead of 121008/4/16).
For this listing I'll assume that geometry.
Units = cylinders of 1204224 bytes, blocks of 1024 bytes, counting from 0

Looks strange
