hd i get the same layout 74.50 gb NTFS C partition and the EFI

This is a limitation of cloning a drive, the partitions must be changed during the process, but cloning does not allow this.

You are better off to make a full disk Image of the old drive, then apply that image to the new drive, this will allow you to change partition sizes during the process. I just did this for my T60, went from 60gb to 250gb, and the software I used correctly re-sized the C partition to use the rest of the increased size of the new disk.

I used this software to image the old disk (all partitions), then applied that image to the new disk. It will ask you near the end of the configuration if you wish to keep the partition sizes or use the entire space, choose the latter.
