Case 1: The Linux installation is on a seperate Harddisk
dd if=/dev/hd[a,b,c,..] of=/dev/hd[a,b,c,..] bs=2M
Part of Sourcedrive : if=/dev/hd[a,b,c,..] the Letter "a" for the first Harddrive, b for the second, ....
Part of Destinationdrive : of=/dev/hd[a,b,c,..] the Letter "a" for the first Harddrive, b for the second, ....
Case 2: The Linux installation is on a Partition
(e.g. hda1 is the Partition with the Linux installation and hdb1 is the Destinationdrive)
dd if=/dev/hda1 of=/dev/hdb1 bs=2M
