using dd for cloning

[Gilles Gravier]

That's the correct syntax.

You can change bs to something bigger... bs=1024k for example.

Note, it's not guarantied to work if the disks don't have identical
geometry. I would do that with similar disks.

It will take time, and NOT TELL YOU about its progress... so wait for it to
finish. You should see the disk LEDs blinking.

Another option is to tar cf - /YourFirst Disk ¦ tar xvf - /YourSecondDisk

The v in the second command will list files as they are processed.
