Acronis True Image 2015 18.0 Build 6525 - HDD backup

Hi all,
I have a problem that I think is not a problem ;-) and maybe someone can help me to solve it ...

Situation:
- 2 HHD SATA 1TB each used as secondary storage, they crashed both
- I bought two new HDD SATA 2TB each, the bios recognizes them, Acronis recognizes them

Problem: when restoring the backup i previously made with Acronis on new 2TB disks (I do not know for what mysterious reason) Windows 7 Ultimate recognizes them only up to 1TB, as if they were still the old HDDs.

Question: How do I restore the backup on the new 2TB disks and let W7 recognize 2TB disks instead of 1TB?

Operative note: i use MBR with all of my disks.

Thanks a lot,
Regards/Ciao!
