Matshita DVD-RAM UJ850S not working

  1. I have a Toshiba A215-S5839. It has an AMD Dual Core Processor and 2 gig of ram. Installed in the laptop when I purchased it was a Matshita DVD-RAM UJ-850S. I have always had some problems with the drive and would often have to reinstall the driver. Reinstalling has stopped working. Now it will not read data dvd or cd's at all. Comercial Video DVD's play, but all that can be see is moving blocks. I tried your registry trick and it crashed my computer. I was worried I wouldn't be able to get it back. All the rest of my drivers have been updated and seem to be working properly. I have all the proper codecs and my DVD drive is set for the proper DVD region. I'm at a loss. Please help...

    On the one hand i'd say it's probably defective and time to replace.. tho on the other hand, is odd, if you're saying reinstalling the driver seemed to fix it?? Let alone the registry fix crashing the machine???

    1. What Service Pack level is installed?
    2. And let's take a quick look at the filter drivers loaded for your device

    Also... you said you had been "re-installing" the drivers.
    > Have you been downloading a vendor's driver? If so, where from? or can you give me the link you are using?
    > Or are you just uninstalling whatever you found in Win 7 (ie using standard drivers in Windows 7? if you know?)
    > In part, just curious to check on/ know where your toshiba filter is coming from

    I'm gonna break this up into 4 posts so I can send the atachment you asked for.

    What is on there right now is a driver running in compatability mode for windows vista service pack 2 that I got on the toshiba site I'm about to give you. But I have tried the drivers from microsoft with the same result. I will give you that link when I reach five posts.

    Not to throw a rench in the coggs, but it read an install disk today for a cisco wireless router. I also forgot to mention is it will run the windows 7 install disk from boot. That install was a reinstall about a week ago after i got some "bad" advice from a few users to edit the registry and remove a filter. It crashed my computer in a way I had never seen. Not even a system restore was able to recover it. I wiped all petitions of the hard drive except the bios portion and reinstalled windows 7. That's when I started playing with both microsoft's drivers and toshiba's drivers. I don't know if that info helps. But I thank you for your help anyway.

    Hmmm.. i skimmed the info for a few things but didn't have an "Ah HAA!" moment (i.e. nothing in particular popped out at me). But here's some thoughts

    1. Try running from a boot Cd and test your optical drive
    If your optical works when running under Knoppix - an alternate OS (for example), you'll know it's a Windows problem. Otherwise it's likely hardware or firmware problem. See How to recover your folders/files when Windows won’t boot and follow step 2 to create an optical CD. Then try playing music

    2. Firmware
    NeroInfo Tool tells us the optical drive is running Firmware Version : 1.40. You might google a bit to see if any newer firmware version availbale that might be worth trying

    3. Filter Drivers
    On the one hand, i don't know why removing CLASS filters should have crashed your machine so badly
    > Unless maybe you received bad instructions?
    > Or you possibly removed the wrong registry key???
    Do you remember the link that gave instructions?? - just curious to see it, if you do)

    Normally, one would only be removing CLASS filters. For your current case, i see you currently still have one filter installed and its a DEVICE (not a CLASS) filter.

    Do you now (or did you used to) have a Toshiba Backup Utility installed? Seems that Driver Name: tdcmdpst.sys
    is part of that tool. If still installed, reboot, then use Revo Uninstaller to uninstall it. You might check Filter Load Order Tool also to see if it's disappeared. Then retest and see if it makes any difference

    /* btw */
    If it happens you've ALREADY uninstalled that Toshiba Backup tool it would seem it left behind a filter driver!

    Okay, As far as option 1, I can boot with the drive. I can't play a cd, but with some coaxing, I can get it to rip a cd. Also with some coaxing, I can burn an audio cd. I have looked for firmware for the drive surching in google with
    Matshita DVD-RAM UJ850S and all I keep getting is links to sites that give me a program I have to pay for that search for drivers that need to be updated. The DVD driver is never one of them and I never find firmware.

    As far as the filter drivers, like I said, I am running the drivers from that toshiba link that I gave you. I am currently running them in compatability mode for Windows Vista Service pack 2. I have the original drivers disk from the laptop that I burned with the recovery disks as soon as I got the computer. But the drive won't read them. Im going to change my boot order and attempt to run the driver disk from boot. If that works, I will reinstall from there and let you know.

    I can't find the link for where I got the registry manipulation. It was in a thread on microsoft answers I can't find.

    Ok. I changed my boot selextion and began with the recovery disks that I made when I got the laptop. Disk 1 (the bootable disk) ran with out a problem. I went into the repair utilities to locate and up date my drivers, hit the icon to load drivers, and inserted the disk with the drivers and utilities that was burned when I wrote the recovery disks. that disk wouldn't read. I still have the boot order with the dvd drive first and I'm taking the disks with me to school this afternoon. I will pop on periodicly to try to move this along.

    As for option 1, i think you misunderstood my intent.

    The point was to boot into Knoppix and so you can then see if the your audio CDs will play when running under Knoppix and using its media player. (Thus you can test your hardware when booted into a completely different OS then Windows! to help see if it's a Windows vs. a hardware/firmware issue)

    Though from the sounds of it, if you're still having problems when you try booting from/running your recovery CDs, sounds like its time to replace the optical drive :(
