This is for a Sony laptop that runs OEM windows 7 home premium. If I just clone over, will the os become locked since the hardware has been changed?
On side note, how to do the cloning properly so that the first sector of the 2 drives will align correctly?
Windows activation rely on a lot more hardware signatures than just the harddisk. thins like processor, motherboard, MAC address and more. The harddisk being replacement (and very frequently) yet same computer, will not singularly trigger a re-activation. I have done HDD to SSD on 2 Asus R303CA about 6 months ago Win8 and no need re-activation. I redo 1 recently to another new SSD.
Regarding alignment, for SSD it is actually partition alignment. Not aligning with the source HDD. This is so that things are written to one allocation block and not across 2 allocation blocks. Reason is that if properly aligned then any write and erase is on 1 block and not 2. Since SSD lifespan depend on a finite number of write/erase, a properly aligned SSD means maximum life while a non aligned SSD last only half as long.

Remember to turn off defrag, reason same as for life-span. The more you wrie/erase, the shorter the SSD lifespan. SSD is so fast and the technology so different (no spinning platters, no moving read heads) from HDD, defrag will not matter any more.
