Re: Hp Pavilion dm4 LW475UA#ABA DVD write not working



First, try the automated fixit from Microsoft on the link below.


Windows 7




Check if the drive is now working.


If it still doesn't work, click the Start Menu, open All Programs, open Accessories, right click the Command Prompt and select 'Run as Administrator'.  In to the prompt type the following command and hit enter.


sfc /scannow                 ( note that there is a space between sfc and the / )


Let the process complete, then type exit and hit enter. 


Next, click the Start Menu, open the Control Panel and click on Device Manager.  Next click to open DVD/CD-ROM Drives.  Right click the drive and select uninstall.  Do not delete drivers if asked.  When the device has uninstalled click on the 'Scan for Hardware Changes' icon ( usually just below Help on the toolbar ).  Let windows reinstall the drive and see if it now works.
