It is recommended to put the new drive in the laptop first, and connect the old drive via USB. Note: the first section of the above KB document directs laptop users to KB 2931: How to clone a laptop hard drive - and has the following paragraph: Please see KB 56634: Acronis True Image: how to clone a disk - and review the step by step guide given there. Moving from a 1TB HDD down to a 120GB SSD sounds likely to be a very tight fit unless you have very little data and applications stored on the source HDD drive - you need to be looking at having around 20% free space on the SSD after the clone is complete, so really your data needs to fit into around 90GB max, which won't leave you much opportunity for any future expansion or growth! How are you trying to perform the Clone operation here? I would assume that you are attempting this from within Windows and probably with the new Crucial BX500 SSD connected externally, which is not recommended on either count. See KB 2201: Support for OEM Versions of Acronis Products which applies to your OEM version of ATI from Crucial.
