You may have to install the AMD chipset drivers manually. If you open the Device Manager and expand 'IDE ATA/ATAPI controllers' what is listed? If the 'Standard AHCI 1.0 Serial ATA-controller' is listed can you obtain the Hardware Id for the device: Right-click 'Standard AHCI 1.0 Serial ATA-controller' >Properties >Details, then choose 'Hardware Ids' from the drop-down menu under 'Property'. What is listed under 'Value'? Also, can you locate the folder that the AMD chipset drivers were unzipped to?

Go to Device Manager find the cd rom right click and select properities select Driver tab select Driver details. Make sure both ( 2 files) are coming from Windows system32 DRIVERS cdrom.sys and Windows system32 DRIVERS GEARAspiWDM.sys. I found after loading some software the systekm changed my driver to the 64 bit version after removing the file under windows I moved it to a temp folder just to be safe the re booted the computer it went and found the 32 bitr version and everything works ok now. Hi, Has anyone found the cause of incorrect function for this device, I have justed upgraded my system to WIn7 64 bit and now my TS-L633A device cannot burn. At first it would hang at the end of the burn process, It would physically burn but fail at the end and the system sees it as a blank DVD.

I have run MS Fixit and now CDBurnerXP performs the burn and reports that the DVD has been burnt, but when looking at the DVD+R it has not actually physically burnt into the DVD, putting the DVD back into the system brings up the 'How do you want to use this disc.' Window, as if the DVD is blank. Leaked Source Code Of Symantec Product Upgrade.
