Need DVD Driver for Toshiba Satellite L40 17U laptop.

[Indratej]

Hi I am using Toshiba Satellite L40 17U laptop from a while now. Yesterday when I tried to view videos store in my DVD disk by inserting it inside the DVD/CD ROM drive, I came to know that it is not working. So I just went to the Device Manager and tried to figure out what is the matter. I saw a yellow exclamation mark on my DVD-RW DVR-K17A ATA Device. On right clicking it and checking the properties the following message is prompted: "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)" So wanted to know where I can find the appropriate drivers for my DVD/CD drive.

• Right-click the CD and DVD (DVD-RW DVR-K17A ATA) Device, and then select Uninstall.

Code 39 for an optical drive is due to corrupted registry entry. The problem can also arise because of some CD/DVD driver issues. The problem can be solved either by editing the registry entries in Windows Vista and Windows XP. In Windows 7 you can solve the problem with the use of in-built troubleshooter (Playing and Burning CDs, DVDs, and Blu-ray Discs troubleshooter). But you should always remember that changing or deleting some wrong registry entry can result into many problems, so it is better you backup your registry.

Windows XP users should follow the below steps to edit registry file and solve the issue.

• Registry Editor Window will appear. Now go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318} and select the {4D36E965-E325-11CE-BFC1-08002BE10318} .
