Thanks Samson and Julian
Well, it worked, in spite of my Macrium being v4!
Going one step further, the wizard showed the new drive when he was asking to choose one to write the image on, and I got the job done!
Now, could you give me some advice?: my OS is Vista, I'm not intending to change to another Windows for now; as, how it's said, Vista is not prepared to use the trimming SSD function, what should I do to overcome this and get the best from my new drive?
