I have a 512M CF II drive that I want to copy to a 1GB CF II.

I've tried using dd, and it "seems" to work until I do an ls on the new drive. I think the probem is that the 512 has 1015 cylinders of 1008 * 512 bytes and the 1G drive has 992 cylinders of 2016 * 512 bytes, so the format copied by dd doesn't correspond to the actual drive.

I used:
dd if=/dev/hda1 skip=2 of=/dev/hdc1 seek=2 bs=4k conv=noerror

This in order to conserve the partion table of the second.

Is there a way to reorder the cylinders through bs= or something?

I tried other methods like dd'ing to an image and then mounting the image to copy it to the drive, but I seem to loose some permisions in the copy (or something like that). For instance mysql starts then stops, telnet sees a different TERM configuration, ftp restricts my permissions and other strange stuff.

What can I do?

You can't do that with dd; you will always wind up with the larger drive being seen as a 512MB drive. The method you tried with creating an image and copying the files should work. To avoid the permission problems, use tar to do the copy instead of cp. Assuming your dd image is mounted at /mnt/image and your new larger drive is mounted at /mnt/big, you would run as root:

If you want to use cp instead, it will probably work with:

Those are the two most common methods I know. tar usually works better for me re perms and links than cp. Also, it's a good idea to be root as many times you will have files on the drive to be copied that are only readable by root
