After researching why I was unable to successfully play Halo 2 on my Xbox 360, I found numerous articles that have brought me to the conclusion that I bought a counterfeit hard drive off of eBay a couple years ago. (source 1, source 2)
Sadly, it seems like I'm not going to be playing Halo 2 with this hard drive since it is missing the second partition that allows for reverse compatibility with original Xbox titles. According to the sources I've read, my only option is to get a new hard drive.
While I really don't want to have to buy a new Xbox hard drive, would it be possible for me to play original Xbox titles using an official Xbox 360 flash drive?
I saw one of this nifty 8GB storage flash drives, and I think that would work best for me if they work with the second partition that my Xbox seems to lack. It's the 8 GB USB 2.0 Flash Drive by SanDisk that I'm looking at.
Hopefully I can get to play some original Xbox games with a flash drive!
