I installed an Intel 320 80GB SSD into my laptop today. Intel has their own version of Acronis but it wouldn't clone from a large partition on the mechanical drive to the smaller SSD. I downloaded Easeus Total Backup and it did the trick. I had previously bought an external 2.5" USB drive enclosure. I put the SSD in that, connected to the laptop, downloaded and installed Easeus TB, ran it and told it to do the complete clone. A little over an hour later it was finished. I took out the mechanical hard drive, put in the SSD, turned the machine on and it booted just fine.
