Hi, I have had this problem for maybe a week now. My xbox will take extremely long to start up and I get an error code a lot telling me that some content is unavailable. Everything runs super slow and I cannot go to my friends list from the guide, as it will freeze for 10+ minutes every time. I have cleared the cache, deleted a lot of data from the HDD, and deleted and recovered my Gamertag. My xbox runs fine without the hard drive inserted. Help is appreciated, cheers.
