I guess if you were low on cash and opted for the 4GB model, you're kind of screwed:

I hope they fix this, it'll be a pretty unpleasant surprise for a lot of people. 

LULZ? 
 
That's definitely messed up.  I wonder why that's happening.

That... sucks...

Welcome to mycrosoft.  lol  
 
Great way to get people to buy shit.

It's really weird, since the multiplayer works fine...how can you have a working multiplayer but not co-op? I don't know enough about games/memory/technology in general to know :/

That sucks. I was thinking about picking up a 4GB model but if this is an example of what's to come than no thank you. 

Thats pretty lame, I don't see how anything in reach could cache 4gbs, the disc itself is capped it 6.8gbs

If the article is accurate the worst part is that 16GB of USB storage would not help...that's more usable space than you get out of the O.G. 20GB 360 HDD

Also, if you bought a copy in the UK you're extra screwed, as the Slim hard drives don't go on sale until the end of the month. 
 
Gives you enough time to play through the single player campaign I guess.

That is fucked.

" A patch better be coming. Atleast allow the use of USB drives. "

I know why, 4GB console reads the 4gb as memory unit. Halo Reach requires a xbox 360 hdd for theatre fileshare and coop. I'm getting screwed cuz i have a arcade with 16gb usb drive, and that doesn't work as a hard drive in halo 3, odst and reach. Please take this bungie attention i've already posted a couple of times i hope they fix it

Major bummer.

They could have at least put a note on the box saying that some features require the HDD. :/

I'm pretty sure Burnout needed a hard drive to play online as well.

Ouch. That is pretty sucky. Hopefully Bungie will get a patch out for it soon.

I'm fairly sure ODST was the same way.  I do agree that a USB drive should have worked -- I'm surprised that it doesn't.  With that said if you are in the market for a new xbox you really should get one with a big hard drive -- installing your games is the way to go for silent gameplay.

It's a much bigger security risk to have cache files sit on a USB drive that can be removed and decrypted than to have it stored on a hard drive. "

That would make sense, except for the fact you can install games to USB drives as well. I would think that would be more of a security risk than cache files. ;) "

This makes no sense.

And you're kidding yourself if you don't think that hackers wouldn't just open up their drives and hook them up to a PC to do their hacking in the first place. The hard drive in any 360 is just a 2.5" drive; the same as you'd find in or buy for any laptop. That information is one broken warranty and one bit of software away from anyone wanting to get at the installed game files stored on them.
 
Anyway, I'd like to see some actual investigative journalism on this one. Microsoft's stance (that they're "looking into the issue") makes it seem like an actual bug. Sounds like it was like that in ODST too, so it could very well be an actual limitation of the game engine. If that's the case, I'd like to hear the technical reasoning why. I'm interested in stuff like this.

Why didn't they just mark this on the box?  I just looked at my Xbox 360 games and some of them get very specific like, how much free space you need to save, if its 720p or 1080p etc.  To me, the shitty thing isn't that you need a HDD for co-op, its that they should have just labeled the box as such to inform people but didn't.
