I have a question about the behaviour of a cloned disk.
I want to copy a20GB disk to a partition on a much larger disk (1TB) of 
20GB. The disk is bootable with 2 primary partitions (1=ntfs, 1=ext3) 
and an extendedn partition with 5 logical partitions (with different 
If I copy that disk with "dd if=/dev/sdb of=/dev/sdd8 bs=1024" will all 
be preserved i.e. are all partitions the same as in the old disk and is 
the disk bootable ( and can grub find the bootable partitions 
You can see I don't have much experience with this so I hope somebody 
with more experience can help me out.
