You cannot legally download Diablo I from Blizzard's online store, so this is an illegitimately garnered copy you have. We do not turn a blind eye to this kind of thing here, despite what other fansites you may frequent. Posts are being deleted, infractions given, and if this discussion of piracy continues, it will result in more infractions or bans.
Thread resolved, closed.
Have a great Thanksgiving,
