If there's something we here at iFixit can't do, it's leave a "black box" alone.

We slice open the hard drive case to see who's providing the storage for our particular Xbox.

The 5400 RPM Seagate 250 GB hard drive is pretty cool, but we're more intrigued by what's underneath it.

Closer inspection shows that not only does the hard drive case have a pull tab, it has a spring-loaded pull tab.

A standard 2.5" SATA hard drive means I can safely upgrade my Xbox 360 E, right?

Unfortunately, no. Any attempt to "disassemble, decompile, create derivative works of, reverse engineer, or modify" hardware is a violation of the Xbox Live Terms of Use and may result in enforcement action.
