i recently copied the content of a 4gb solid state ide disk to a regular (2.5'') disk that is 40gb large.
i used the dd command. it worked nearly perfect, except that the system does not recognize the new disk size. i used fdisk to enlarge the last partition. fdisk shows me that the last partition used all available space.
but 'df' still shows the 4gb!? i tried fsck in hope it would find the inconsistency, but it didn't.

what do i have to do, that the system ('df' in the first place) also gets aware of the new disk size?

thanks for the help.

Not use dd to do the copy. Try 'cp' (from a live CD, ie, not while the source drive is mounted).

maybe parted could fix this? Try gparted or qtparted which can be found (probably in your packagemanger) but also in the livecd: http://www.knopper.net/knoppix/

You need to enlarge the filesystem. At present, you only have a 4GB filesystem, so there is no inconsistency for fsck to find.

Just in case the OP doesn't understand.... The partition has been enlarged ok but, the filesystem inside that partition hasn't been enlarged yet.
I do run the fsck before enlarging the file system.
For example:

e2fsck -f /dev/hdb2
resize2fs -f /dev/hdb2

Thanks for your answers.
It worked. The resize2fs did it.
