Can I clone a bigger HDD to a smaller SSD?
"I have an old computer and I'm using about 30% of the 500GB hard drive. I'm afraid that the hard drive will fail to work someday, and it is really slow to load system or perform any tasks. The desktop is running Windows 10 and stores photos transferred from my mobile phone. I bought two disks, a 1TB hard drive and a 256GB SSD. I'm planning to clone the 500GB hard drive to SSD so that the computer can boot from SSD and get a faster speed. However, I have no idea how to clone or migrate OS from a bigger HDD to a smaller SSD! Is there free and simple software that can do this for me?"
