1) Attach SSD to extra SATA port in computer.
2) Install and run
AOMEI Backupper.
3) Chose the clone option.
4) Chose the source as your current 1 TB hard drive
5) Chose the destination as the SSD.
6) Select to align option. You don't need to copy sector by sector.
7) Wait for clone to complete. Once complete power off computer. Uninstall 1 TB platter drive and install SSD to the main SATA I cable. Boot computer. You're done.
I've done this many times. Even with USB sticks and a netbook.
Notes:
You will need to purchase a 1 TB SSD unless you are not using 1 TB. If you are only using say, 220 GB, than a 256-500 GB SSD is all you need.
Some anti-virus software mistakenly reports AOMEI Backupper as malware. It's a false positive. This is what I have heard on other forums.
