copy, burn and resize SD Card Image

To copy the image

apogee@apogee-persiasys:/media/second-drive/apogee/20080918$ dd if=/dev/sdc of=sdimg-1gb-20080918.dd
1984000+0 records in

apogee@apogee-persiasys:/media/second-drive/apogee/20080918$ ls
sdimg-1gb-20080918.dd

To burn the image..

apogee@apogee-persiasys:/media/second-drive/apogee/20080918$ fdisk -l

the new sd card is 2GB while the image is 1GB... so, to resize partition table:

apogee@apogee-persiasys:/media/second-drive/apogee/20080918$ sudo fdisk /dev/sdc
[sudo] password for apogee:

The number of cylinders for this disk is set to 7754.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

then to resize the filesystem:

apogee@apogee-persiasys:/media/second-drive/apogee/20080918$ ext2resize /dev/sdc3
ext2resize v1.1.19 - 2001/03/18 for EXT2FS 0.5b
apogee@apogee-persiasys:/media/second-drive/apogee/20080918$

ok, now we can use this sd card...
