[opensuse] dd question

Hello SuSE people,

I know that you can do a dd if=/dev/sda of=/dev/sdb which actually clones an
entire drive, partitions, links, etc.

Question is can I dd single partitions like dd if=/dev/sda1 of=/dev/sdb1 and
still have the same result ? Partition by partition?

What I'm trying to do is split an OS off a large drive to a smaller one to
gain the partitions back on the larger drive because of that stupid libata
decision. I will put it on a drive I have wiped from a much older OS .Will I
need to paartition the wiped drive first? or will dd do that for me.

Possible? Practical?

RANT ON: For the life of me I cannot understand that stupid decision by the
devs to use libata with it's 16 partition limitation just as hard drives were
getting bigger and bigger. Really really dumb. And someone said they were
working hard to get the large number of partitions back. That was a year ago.
Nothing yet !! RANT OFF

BTW I have copied everything on the "victim" OS with rsycnc. Just in case.

Bob S
