Several years ago, I purchased a XBOX 360. I opted for the XBOX 360 4GB because of price. I thought that 4GB was enough. But with the massive growth in size of software applications as a result of storage price going down, some new games that came out for the XBOX 360, especially in 2014, will only work on XBOX 360 models that have a built-in hard disk drive. Destiny is such a game.
After some serious searching on Amazon.com, I found the perfect drive–a generic 500GB hard disk drive designed for the XBOX 360 slim form factor model.
The drive came in within 2 days.
The most challenging aspect of installing the drive was figuring out how to open the bottom of the XBOX 360 case. I did a search on youtube.com and found a video that showed me how to open it. As it turns out, no tools are required–just your finger to pull a latch, then pry the cover open.
Once the drive bay is open, just push the new drive in until you feel that it has snapped in.
When you turn the XBOX 360 ON, go to the SYSTEM settings and look at the storage section. If everything worked out, XBOX 360 will detect the hard disk drive and will make it available for storage.
