I've tried a search but come up with nothing relavent.

while playing halo from hdd i get dirty or damaged disk error near the end of the game. any ideas?

I used dvd2xobox to copy and haven't had probs with any other game.

Gladius is showing the same signs, and I'm running from the HD. I.e. late game "dirty or damaged disk error".

I get the same error on Legacy of Kain: Defiance. I have tried deleting the game and reinstalling it with PxHDD Loader and it gives me the same error... but it is somewhat random. I have a 4979 bios too so im not sure what to do ;(

EDIT: I just wanted to say that I looked at the freezing tutorial and followed it ;p I've tried reinstalling from scratch, deleting cache, deleting save games, all my IGRs are off (all 3), and my bios is up to date. XBox 1.5 :/
