I. Click on Start->Run->Cmd (to start MS-DOS)ii. Type the command xcopyD:\*.* C:\cdcopy\*.* /v /e (D:\ is the CD/DVD disk drive and C:\ the hard disk drive.)iii. Stop or Exit from all other applications that maybe taking up too much virtual memory or CPU.iv. Restart the computer and try again.v. Restart in safe mode.vi. Switch the disk drive controller to DMA mode following vii. For DVDs, unplug any cables that may be connected to the video outputs of the computer.viii. Update the DVD driver with the latest version of software from the manufacturer's website.ix. Check that the sound card is compatible with the computer and use a DVD decoder for the drive.x.

ERROR CODE

• error codes are enumerated messages that correspond to faults in a specific software application.

Code 19 –Error Message: Windows cannot start this hardware device(CD/DVD DRIVE) because its configuration information (in the registry) is incomplete or damaged. To fix this problem we should uninstall and then reinstall the hardware device. (Code 19)Cause: as the error message states

Error code 39: Windows cannot load the device driver for this hardware. The driver may be corrupted or missing.

ERROR CODE 32

A driver for this device was not required, and has been disabled

• Code 10 This device is either not present, not working properly, or does not have all the drivers installed.

• Code 19 Your registry might be corrupted.• Code 31 The device is not working properly because Windows

cannot load the drivers required for this device • Code 32 (or Code 31) A driver for this device was not required,

and has been disabled • Code 39 Windows cannot load the device driver for this

hardware. The driver may be corrupted or missing.• Code 41 Windows successfully loaded the device driver for

this hardware but cannot find the hardware device.

SUMMARY OF CD/DVD DRIVE RELATED ERROR CODE

These error codes are usually resolved by uninstalling the upper and lower filters. Third party burning software will need to be reinstalled

CD and DVD Troubleshooting

• Power failure, either from the power supply to the drive, or internal to the drive.

• Mechanical failure. The drive has power, but does not eject the drawer or does not perform some other mechanical function.

• Read failure. The drive does not recognize the disc when inserted.

• Write failure. The write function fails to work correctly. The read function does work correctly.

• Configuration. The drive reads the disc properly to some extent, but does not perform all of its functions correctly

Make sure that CD or DVD drive has power by pressing the eject button and observing the drive activity

light. The drive activity light should flash and the drawer should open. If the light flashes but the drawer does not open, either the drive drawer mechanism is broken or jammed, or in the case of -RW drives, the burning software may prevent the drawer from opening until the software has completed its operation.

Make sure all discs used for testing are clean, with no scratches or fingerprints, and are originals (not burned or duplicate copies). Also, oxidation can cause small pits in the recording material, resulting in read errors. Attempt to read or play discs other than the failing one.

If other discs will play, then try the failing disc in another system.

If the disc fails in another system, replace the failing disc.Verify that the drive supports the media that you are trying to

read. For example, a DVD will not read in a CD drive.If the discs are scratched, use different media known to be good.Both sides of the disc should always be protected from

scratches.

• Make sure the drive is recognized and correctly placed in the system configuration utility. The System Configuration Utility is also referred to as the Setup Utility

• Power on the computer and press F1 when prompted to enter the System Configuration Utility.Note: Due to variations in BIOS designs, the terminology and names used in your BIOS may be different.

• Highlight Main, then select System Summary and press Enter. The CD/DVD-ROM drive should be listed as one of the IDE drives similar to that shown below. If not, the drive is not being recognized by the computer during BIOS hardware detection. This condition cannot be changed within the System Configuration Utility and must be corrected. Go to step 7. Otherwise continue below.

• Press Esc to return to the Main menu. • Select Start, highlight Startup Sequence, and press Enter. • Under Primary Startup sequence, set First Startup Device to CD/DVD-ROM. • Set Second Startup Device to Diskette or Removable. • Set Third Startup Device to Hard Disk 0. The settings should be similar to those

shown below.

• Press F10 to save the settings and exit.
