DVD Drives Dissapeared... [Windows Update]

By Jam_Master_K

  1. Sorry to bother you all, but i wonder would anybody be able to help me out with a problem i have encountered.

    Last night I carried out a Windows Update, and i installed all the software updates that were available. However i also noticed that there was a hardware update available too. I decided to install the update as i thought it must be a better driver or something similar.

    The updates were "VIA - Storage - Primary IDE Channel" & "VIA - Storage - Secondary IDE Channel". I have no idea what these updates were as there was very little information on them.

    When i rebooted my computer, both my DVD drive and DVD-RW drives were missing. They were nowhere to be seen in explorer and when i inserted a dvd nothing happened.

    I eventually figured out that it must be the update, but i could not find a way to uninstall it.

    It seems a lot of people are having problems with these 'VIA Storage' updates and lots of peoples computers won't even startup after the update.

    Then i eventually figured out that maybe i needed to rollback the driver on the IDE channels. I did this on the primary IDE channel, in the device manager, and to my joy, the DVD drives re-appeared, and are in full working order.

    Then i tried to rollback the secondary IDE channel and it tells me that 'no driver files have been backed up for this device'. So i am unable to change it. It has an exclamation mark on its logo in 'Device Manager' and when you click it, the message that is displayed is: 'This device is not working properly because Windows cannot load the drivers required for this device. (Code 31) Click Troubleshoot to start the troubleshooter for this device.'


    So, as i see it, i think i have undone the damage the "VIA - Storage - Primary IDE Channel" update caused, however i have not addressed the other update.

    Everything seems to be running fine now but i am wondering, could it cause problems in the future?

    So if anybody has any advice i would be terribly grateful. Oh, and i have a few more short questions...

    • What exactly is an IDE channel?
    • Would my computer definetly have a secondary IDE channel, and if so does it mean that its not functioning now that this update has been installed?
    • Or could windows update just have installed the driver without me having a secondary IDE channel, as when i disable the secondary channel, everything on the computer seems to work fine still.
    • If anybody knows of any other, or better, way to undo the damage, i would be delighted to hear it, as i have very little knowledge of this area.

    Well i decided to uninstal and reinstall the hardware, but it kept installing it with the 'VIA' driver, which is not the right driver for my secondary IDE channel.

    So i decided to have a look in the 'system32' folder for the VIA driver. Once i found it i backed it up and deleted it. Uninstalled the hardware again and rebooted and everything is working good again now. It installed it properly with the proper manufacturers driver.

    Just thought i would post this info, in case anybody has a similar problem in future.
