Xbox error: Disc cannot be read

I get this error occasionally, which is really strange considering its reading the hard drive and nothing else on my hard drive has this issue. I've redownloaded the game several times and have found the error still. I only get this error when crossfire is loading the lazerazor map, and I don't think I'm alone in this. Any suggestions or sympathy?

Lol. Obviously it can't read your disc. There is no disc to be read.

That sucks. Hope you fix it.

Sound like its an issue with the hardrive itself.
