If so: > > dd if=/dev/olddisk of=/dev/newdisk bs=32k Can "dd" also be used to copy to/fro my RAID disks (40G), to a single 40G disk? The latter is of a different brand, but has the same size. In other words: how identical does the geometry need to be? If I can use dd here, I think I will use dd to create a "core" system; and then use additional dumps to backup individual slices.
