Before doing any updates or software changes with the Hard Drive connected to the motherboard, make sure that all connections to the board are secure, such as the disc drive, otherwise you will brick the Motherboard, and will require a new one.

Before beginning this guide, it is best to read through the steps for the hardware portion, as shown here
You will also need a PC running Windows, and a hard drive reader (SATA Data and SATA Power to USB)
Seagate drives have been known to cause issues with XBox One software.

Connect the new hard drive to the PC. Make sure that the HDD is in a location where it will not be accidentally disconnected.

This process requires you to run a script to partition the HDD/SSD.
The links below are for both the download, and the original forum post for the script itself, which was created by user tai1976, of gbatemp.net
Un-zip the file.

Press the Windows key/Start menu and type in "CMD", right click, and select 'Run as Administrator"
Type the command "cd C:\Users\(Your Name)\Downloads\xboxonehdd-master-6.1\xboxonehdd-master\win"
Replace (Your name) with the name of your user profile.

Run the command "create_xbox_drive"
The next steps are to create a drive that has either 500GB, 1TB, or 2TB storage. If at anytime you get confused, there is a readme file in the folder you extracted that can help out as well.

For this tutorial, we are using the first option (a) Replace/Upgrade w/o a working original drive.

Make sure to choose the right drive to format, Disk 0 is almost always your operating system, DO NOT CHOOSE DISK 0.
It will ask you to confirm your selection.
Then you will need to choose the size of the drive you have created.

Once the command line displays 6 lines of long numbers with "GUID" at the top, the command lines is finished.
If this doesn't work, clean the disk with diskpart, link below, and try again.

Navigate to the System Update (X) drive, and create 2 folders, one labeled "A" and one "B"
Extract all of the files from OSU1, and copy everything in $SystemUpdate, except for "updater.xvd"
Paste these files in the folders "A" and "B" that you created.
Copy "updater.xvd" from $SystemUpdate and paste it in the root of System Update (X)
Note that you will need to download the bootanim.dat and store it in folders "A" and "B" as well. There are two different versions you can download one for OG / S or the X. Without the file the Xbox will boot with a black screen to the menu and not the boot logo.

Some users have experienced sign in issues after an ssd upgrade. If this occurs, simply reset the console (keep games and apps if need be.) and that should resolve the issue.
Those who have their Xbox set to "energy saving" mode for startup may experience a 20-30 second black screen before boot. Changing this setting to "instant on" resolves this issue.
Now enjoy 20x faster r/w speeds and loading times a fraction of that of a standard HDD.
