    • If the CD or DVD drive name is missing , the drive is not being detected by Windows. Scan for hardware changes again to attempt to detect the drive. If the drive is still not detected, close Device Manager and skip to Step 3 to reset power and reseat the drive cables if necessary.
    • If a drive name is shown with an alert icon (the drive icon is marked with an alert symbol, ), double-click the drive name to find more information. Do the following depending on what is shown in the Device Status section:
      • If error code 10 , 19 , 31 , 32 , 39 or 41 is shown inside Device Status, a problem exists with the integration of previous CD burning software. Use Step 5 to remove associated control filters from the registry.
      • For any other error, refer to the information that is provided with the error code. For more help and information, refer to the HP support document Device Manager Information (Windows 7) .
    • If a drive name is shown with a disabled icon (the drive icon is marked with an arrow pointing down, ), the drive has been disabled. Right-click the drive name and select Enable . You may have to restart the computer. The drive should work correctly once it has been enabled.
      注 :If the drive cannot be enabled, a required software service or driver is disabled or not functioning properly. Double-click IDE ATA/ATAPI controllers in Device Manager to see if there are any problems and troubleshoot them according to the error codes. Resetting the BIOS may also resolve this problem. To reset the BIOS: restart the computer, press F10 repeatedly at startup to open the BIOS Setup Utility, press F5 to reset the BIOS values to their default setting, and then press F10 to save and exit.
    • If the CD or DVD drive is listed as normal , with no special icons , Windows is detecting the drive but other software used to burn discs may not be detecting the drive. Use step 6 to make the disc burning software detect the drive.
  • Windows 7 includes a troubleshooter that checks hardware, such as CD or DVD drives, for problems. Follow these steps to use the Hardware and Devices troubleshooter to check for problems:
    1. Click Start , and then click Control Panel .
    2. Under System and Security, click Find and fix problems .

      图 5: Troubleshooting computer problems
      If you are prompted for an Administrator password or confirmation, type the password or provide confirmation.
    4. Click Next .
    5. Windows checks for problems. If the troubleshooter detects problems, follow the instructions to fix the problem.
      If the drive is still missing after using the troubleshooter, continue to the next step.
    Under certain writing conditions the drive might lose communication with Windows - even after restarting Windows. To reset the drive, fully turn off the computer by selecting Start and then Shut down from the power menu. Wait five seconds for the computer to fully power off before turning it on again. If the drive is still missing after resetting power, continue to the next step.
