    DVD-RW won't burn - Toshiba Satellite Pro C850


    Hi all


    For some reason, neither my internal nor external DVD writers will burn DVDs. My internal DVD-RW is a tsstcorp cddvdw sn-208ab. Th external DVD-RW is a tsstcorp cddvdw se-208db.


    For a while I could burn a DVD by using "Fix it", but then I'd have to reboot, use "Fix it" again, but now that doesn't work at all.


    Sometimes there is one driver shown (C:\WINDOWS\system32\DRIVERS\cdrom.sys) and sometimes there is a 2nd driver (C:\WINDOWS\system32\DRIVERS\GEARAspiWDM.sys).



    I've tried uninstalling the DVD-RW drives, and rebooting.

    I installed the Gear driver update, but then I couldn't find it in its location.

    About 6 months ago, I had similar problems and fixed it by deleting registry keys (upperfilters & lowerfilters), and that fixed the problem at the time.

    Maybe I need those keys back? One site recommended adding an UpperFilter within the same folder, containing the text "GEARAspiWDM" & rebooting, which SOMETIMES allows me to burn ONE disc, then the reg key is gone.

    I tried uninstalling the most recent Windows update, but it made no difference.

    I have used a range of burning software- doesn't seem to make a difference.

    Any suggestions would be appreciated

    Welcome to the forum!

    Gear driver is not something I would want on my computer: GEARAspiWDM.sys Windows process - What is it?

    Ok, thanks.

    Here's a couple of clues to solve my riddle:

    1. When I view the drive's properties, it labels it a "CD-ROM". Same with the external drive. But the icons both say DVD-RW.

    2. When I open itunes, it alerts me that I won't be able to burn discs because of the registry settings.

    Hmmm.

    My point was I would get rid of Gear. That's all I got.

    Might give CDBurnerXP a try. Yes, it does work on Win8/8.1. I've seen it work where other things didn't.

    It's definitely a problem with the drivers or the registry - both the internal & external dvd-rw.

    Both have C:\WINDOWS\system32\DRIVERS\cdrom.sys as their drivers, which can't be right since they're not cd-roms.

    I've just realised neither drive will play DVDs :S

    Thanks to those who suggested different burners, but I've tried the best & the rest already!

    Mine shows the same and yet works just fine, both as DVD and CD reader and writer.

    I'm missing the second driver and your screen shot isn't clear enough for me to read!

    Can you please type the name of the driver? Thanks

    C:\windows\System32\Drivers\PxHlpa64.sys but I think it's proprietary for my Pioneer DVD-RW DVR-112D machine. The first one (cdrom.sys) is part of a driver ever since DOS days and it had to be included in Autorun,sys for CD to work.
