I've only done the cloning process a few times, and only with Acronis True Image (which is kinda spensive, but I've been using it for years so I stick with it, I know it works). The free 30 day trial of True Image, you can't clone a disk, but make a full back up of your C: drive, and check the options to only back up the data, not the free space and such like that, then put your new drive in and restore the backup to that drive and when you do just select to make the drive bigger. It sounds daunting, but really, if you mess around with it for a small while it's pretty easy, and if you leave your original C: in tact, make the backup (you'll have to restart and it will load a True Image thing so you're not in windows for the backup), then restore, put the back up on the extra space you have on your drives all ready, you can choose anywhere to save the backup, then you'll actually have two copies of your C: drive in case one gets messed up somewhere.
