Defective Dreamcast GD-ROMs

While Sega of America claims that it has tracked down and replaced all of the defective Dreamcast games on retail shelves, we are still being bombarded with e-mails from readers claiming more faulty GD-ROMs. Today, we have uncovered methods in which to spot a flawed GD-ROM disk.

Upon examining a faulty GD-ROM up close, it's possible to see where the settlement process went bad – there is a jagged, uneven ring near the outside edge of the disk. This is where data was not properly burned.

The GD-ROMs are also labeled with a distinct production number that can identify them as being faulty. Although not officially confirmed, and only based on our research, disks with numbers beginning with “92_ _” are from a Sega plant that produced the faulty GD-ROMs.
