    Hi,
    I have a 2TB mechanical drive I use for ClearOS (binary compatible with Centos) which had 4 partitions, sda1-4. The O/S in on partitions 1-3 and data is on 4. I wanted to split partitions 1-3 to an SSD and make the SSD bootable. Partition 4 will go to separate drive and the data can easily be transferred using rsync while the server is offline.
    How to I transfer the first three partitions and make the disk bootable?
    Does it even make sense to do this or will block alignment end up being all over the place for an SSD?

    Sorry, I was never notified of a reply and I missed this, but thank you anyway. Time has moved on a bit and I have rsync'd the fourth partition to a new disk and I am now running my data from the new disk.

    Am I right in thinking that if I just delete sda4, that will leave sda1-3 intact and smaller than my new disk, so I can just use Clonezilla to clone the disk across to the new disk as it will ignore the space without a partition?
