Help with halo!

I have backed up my CD to iso and burnt a backup using Alcohol 120 when I attemt to install I get the maessage “Halo encountered a disk error while writing to the file C:…\d40.map make sure your hard disk is not full and the file not in use”

Any clues? is this just a bad iso or is this some form of copy protect/

deja vu ?

have looked at all the old posts but no one seems to have had this problem
