I have an Ubuntu Server installation running on an older 400GB Western Digital 3.5" drive and want to change to a notebook drive. I've done this once before, but didn't run into these particular problems last time. On my other server, I did later add two 2TB drives that were WD EARS drives so I had to configure them for 4k at that time.
When I set up this box, I used LVM. Information about the existing setup is shown here:

So, I picked up a Black Friday 640GB Seagate drive that was in a GoFlex enclosure, $54.00, not thinking that it might be a 4k drive, which it is. When I first went through fdisk on the notebook drive, it told me that the first partition did not begin on a physical sector boundary, which was my first clue that there was a problem. After some monkeying around with it, I have the following:
Disk /dev/sdb: 640.1 GB, 640135028736 bytes
255 heads, 63 sectors/track, 77825 cylinders, total 1250263728 sectors

Disk identifier: 0x43f5b54a

/dev/sdb1 64 156282965 78141451 8e Linux LVM
How do I go about migrating data from my old drive to my new one? The first thing I read about was using a Live CD and DD to duplicate the drive, but I don't know if the advanced format drive will cause problems or not. I thought about adding the new drive to the volume group and then the Live CD to migrate, but I can't unlock the original drive in order to add the new one, most likely because root is on the drive. The third option I can think of is to do a new install on the new drive, then rsync everything over, but I don't know how to do a clean install on a 4k advanced format drive...
Help!!?? :(
