Replacing The Xbox One S Hard Drive With An SSD | Step-By-Step

An Xbox One S accepts a 2.5-inch SATA SSD, but the console then needs an offline USB system update before it will boot.

Microsoft never sold this as an upgrade, and no menu inside Settings will get you there. Anyone replacing the Xbox One S hard drive with an SSD is signing up for two separate jobs: a teardown with a Torx driver, then a system restore from a USB stick. Skipping the second half is where most of these projects stall — the new drive arrives blank, and the console has nothing to read.

Both halves are well documented. The physical work runs about an hour on a flat table with the correct bits, and the software half is a download plus one option inside the startup tool.

What To Have On Hand Before You Open The Case

You need a 2.5-inch SATA SSD, a Torx T10 driver, a plastic opening tool, a USB flash drive of at least 6 GB formatted NTFS, and a Windows PC with internet access. A labeled tray for screws is optional and worth every cent.

Drive choice is the one genuinely open question, since the repair documentation covers the swap itself but does not bless a particular model or capacity. Our tested Xbox One S SSD picks compare 2.5-inch drives that fit the stock mount.

Unplug every cable and work on a stable, flat surface. The clips at the rear, near the warranty sticker, are the brittle ones; a plastic opening tool works them free without gouging the shell. Prying at that seam with a screwdriver is how consoles end up with cracked plastic and a service claim that goes nowhere.

Xbox One S SSD Swap: Screw Order And Connector Care

The swap runs nine steps, and two of them decide whether the console survives: releasing the case clips without snapping them, and pulling the drive connectors by their plastic bodies rather than their wires.

1. Turn the console off, unplug it, and set it bottom-up on the table.
2. Work a plastic opening tool around the rear near the warranty sticker, then along the sides, until the lower case separates.
3. Remove the six green 50 mm chassis screws, labeled F1 through F6, with the T10 driver.
4. Lift the interior metal chassis out of the white shell to reach the hardware.
5. Flip the console and remove the two 10 mm T10 screws holding the hard-drive enclosure.
6. Lift the enclosure and unclip both plastic connector bodies from the motherboard. Do not pull the wires.
7. Take out the four black 10 mm T10 screws holding the drive in its black plastic mount.
8. Move the mount and cable assembly onto the SSD, seat it back in the enclosure, and reconnect both motherboard connectors.
9. Reassemble in reverse, and never power on with a connector half-seated.

Screw positions drift between revisions: some consoles use C4 and C5 for the drive enclosure, others C3 and C5. iFixit’s Xbox One S hard drive replacement guide notes both, so photograph the layout before anything comes out.

All-Digital Edition (Model 1681) Changes

The All-Digital Edition is a different teardown with a different bit set. iFixit’s All-Digital guide lists six green 50 mm F1–F6 screws, two 15 mm front-panel screws on a T8 driver, and two 10 mm C3/C4 screws for the hard-drive case, with four more 10 mm screws on a T8 security driver freeing the drive from its plastic carrier.

These steps do not carry over to an Xbox Series S, which uses a different internal SSD arrangement entirely.

What Does The Console Need Before It Will Boot Again?

A blank SSD needs an operating system, and the console gets one from Microsoft’s offline update package on an NTFS-formatted USB drive of at least 6 GB. That procedure covers Xbox One consoles other than the original Xbox One.

Download the package on a Windows PC, extract its contents to the root of the USB drive as directed, plug the drive into the console, and choose the offline update option inside the Xbox Startup Troubleshooter. Microsoft lists that path as the response to startup errors including E101, E200, E204, and E207.

One honest limit: if the new drive is not laid out the way the console expects, the offline update can fail, and the published pages stop short of a full SSD partitioning routine. A console that still refuses to boot may need a reset or a repair. Games and saves tied to the old drive can also drop out of reach unless they were synced to your Xbox account first — a drive swap recovers nothing on its own.

The order that keeps this job moving:

1. Sync saves and confirm your games are tied to your account.
2. Label every screw by position as it comes out.
3. Fit the SSD into the original mount and seat both connectors.
4. Format the USB drive as NTFS with 6 GB or more free.
5. Extract the offline update files to the root of that drive.
6. Run the offline update from the Startup Troubleshooter, then restart.
