If you've ever tried to read alpha/beta/prototype game data from Microsoft Confidential burnlab discs to no avail, instead of the data being corrupt, chances are, the disc has a gold alloy layer (instead of silver) and you're trying to read it from a DVD or Blu-ray drive. The problem has to do with the reflectivity of the gold metal layer of the disc. Long story short, most DVD drives and likely all Blu-ray drives simply cannot read the information on gold alloy discs due to the disc surface not being reflective enough to have its information read. DVD drives tend to yield the most deceptive results, because they can sometimes read some of the information, thus making it appear as though the drive works fine but the disc has corrupted data in spots. Solution? Pick up an old CD-R/CD-RW drive! The model I use is the HLDS GCE-8400B. There are usually plenty of them on eBay which you can nab for between $10-$20 (including shipping). I realize this is a fairly niche "problem," but figured I would share in the event that it helps someone!
