"Ok so how do I plug the new drive into my PC"
- Laptop or Desktop machine ? Laptop can be awkward. I assume you have Windows on a different HDD\SSD so both drive bays are filled.
In this case you will need to use an external HDD enclosure and connect via USB.
Desktop is just a matter of popping the new drive in a spare drive bay, connecting an SATA cable between the HDD and spare SATA port
and one of the extra HDD\SSD power cables to the new drive.
- As long as your Windows is intact you will have no problems simply copying all game files to the new HDD.
The only time you would have problems is with a clean reinstall of Windows as this wipes out any Registry keys used by the games.
- I also keep a clone of my Windows as a precaution to avoid having to reinstall my disc based games should my Windows SSD fail,
but with games from Steam, etc. you can even do a clean reinstall of Windows, and after reinstalling the Steam client and jumping though
a few hoops (instructions can be found at Steam > Faqs pages) you can run your games without reinstalling them.
btw - I was of the impression that, while you can choose different locations to install games from the MS Store, you cannot copy them to
a new location after they have been installed.
I generally copy and backup new game installs to new drives in smallish (around 100GB) batches as a precaution against the small chance
of file corruption.
Keep your old HDD for backups should your games HDD fail at some time.
- If your Windows is on the same drive as your games, and particularly if the games on in the default location - Program Files (x86) -
or maybe Program Files (64bit games) you would need to clone the whole lot to the new drive.
This would take a long time with a 4TB drive, and is a big reason for never installing games to the default location, or anywhere
else on the C:\ partition\drive.
