Difficulty: Moderately Easy
Step1
Select a hard drive with enough space to hold all of the games and media you wish to carry with you. Look for drives with 7200-RPM specifications for faster speed when loading and caching games.
Step2
Format the hard drive to FAT64 using the Windows format utility. Drives larger than 32 gigs will require third party formatting software although Windows 98 is capable of formatting up to 127 gig drives.
Step3
Turn off the power and remove all cables, including the audio, video and controller cables. Lay the Xbox on its side with the front facing you. Look at the left side and pull the hard drive cover away from the console gently.
Step4
Place the hard drive over the Xbox hard drive bay with the tapered end towards the front of the console and the connector end toward the bottom. Connect the cable carefully and verify no pins have bent.
Step5
Align the hard drive slot with the back of the drive and set it into place until you hear a click. Press the cover on carefully and connect all of the cables. Turn the power on and verify the Xbox powers up properly.
