Some discs run correctly, but others do not.
If the problem is with an application CD-ROM, refer to the
software's documentation and check that the hardware
configuration meets the program's needs.
The color of the materials used to make the disc can affect its
reliability. Silver-colored CD-ROMs are the most reliable,
followed by gold-colored CD-ROM. Green-colored CD-
ROMs are the least reliable.
