How to Add or Replace a Hard Drive in Xbox 360

Xbox 360 uses proprietary hard drives—standard laptop drives don't work directly.

Official Options

• Xbox 360 branded HDDs: 20, 60, 120, 250, 320 GB. Buy used/refurbished (eBay, GameStop).
• Xbox 360 Memory Units: USB flash drives (16–512 MB, older) or configured USB sticks (up to 32 GB).

Install Internal HDD (All Models Except Original "Fat" Top-Load)

1. Power off & unplug.
2. Flip console; press release latch on drive bay (bottom/side).
3. Pull out old drive (if any).
4. Slide new drive in until click.
5. Power on → Format when prompted (erases drive).

Alternatives

• USB Flash Drive: Settings → System → Storage → Configure Custom USB Device (max 32 GB).
• Xbox Live Cloud Saves: 2 GB free with Gold/Core.

Warning: Third-party caddy adapters for laptop drives exist but violate ToS and risk bans. Use official drives only.
