Thanks for the reply. I've actually been working on clearing the cache, because from reading other posts it looks like that might help. But I've run into a little problem.
FTP'ing into the Xbox, I can clear the /mnt/E/CACHE/ folder with no problem. Also, I was able to delete files from Y and Z. So they are apparently empty. For some reason, though, there are files in X, and I can't seem to touch them. When I try to move/copy/delete/rename them, I get this message: Response: 550 Could not delete /mnt/X/P: Read-only file system
The files and folder listed under X are: ¢É, one named 4, one named P and then one blank folder. I have no clue what this means, but I'm unable to delete it. I tried booting Halo 2 after deleting all the stuff but this, but I have the same problem with it freezing.
Could the files in the X portion be the culprit? If so, any idea how I can get rid of those? I'm able to FTP and telnet into the Xbox.
Thanks a bunch for the help!
