Probably you don't want a 4G partition table, a 4G partition,and a 4G filesystem on your 8G card, but that's what you'll get when you use dd. This should work, unless you have bad blockson your 8G, which dd will just assume are good. To use theadditional space, you would need to expand the partition, resize the filesystem, and maybe thenedit the /etc/fstab file for new UUIDs. The alternative is to partition the 8G disk theway you want it, setting the size of root, and decidingif you really want swap. Format the partition(s) withthe filesystem you want -- maybe no journaling on anSD card, so ext2 or ext4 without journaling. Copythe files over with any copy program which can copy fileattributes and not follow links (look at the option switches).tar works just fine with the following:
Get the new UUIDs with
Edit the /etc/fstab with the new UUIDs.Install grub to the 8G disk (assume it's sdc)
Bad blocks on the target card should be recognized and avoided, so you get a working system without a perfectcard.

ubfan1What filesystem?
For ext, you can create an 8gb partition, then use DD to copy the 4gb partition on top, then use resize2fs to expand it to fill the space.
There might be similar utilities for other file systems.
