I have managed successfully to clone my existing 80GB SSD onto a new 240GB SSD using the instructions mentioned in my first post. I have followed the instructions exactly except for those parts that relate to managing partitions : My exiting SSD and new SSD are not partitioned. However although the operating system transfer is successful, on completion the reported size of the new 240GB installed SSD is reported by Windows Explorer as still 80GB. I completed the transfer with the command prompt command "winsat disk" as included in the instructions.
Does anyone have any idea why the reported disk size is wrong. Perhaps I should have followed some of the partition instructions after all.
