Toshiba A45 Series manual 220, Secondary IDE Channel DMA setting

220	If Something Goes Wrong
	Resolving a hardware conflict

You press the disc eject button, but the drive tray does not slide out.

Make sure the computer is connected to a power source and turned on. The DVD-ROM or multi-function drive eject mechanism requires power to operate.

To remove a disc without turning on the computer, use a narrow object, such as a straightened paper clip, to press the manual eject button. This button is in the small hole next to the disc eject button on the right side of the computer.

Never use a pencil to press the manual eject button. Pencil lead can break off inside the computer and damage it.

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.
