Dissapearing drives RRS feed

  • Question

  • I realise this has been posted previous however the fixes I've seen don't appear to be doing anything.
    It's not an issue I personally have on Vista 32, however I've had several other systems come into me on Vista 64 displaying odd symptoms - when non-original discs are inserted (Not talking pirate copies here, just any CDR/DVDR/RW media being used) the optical drive dissapears.
    Event viewer shows the drive has been "unexpectedly removed from the system" and after a restart it's back there and works with other discs. Put in a DVDR and bang - the dirt is gone! (sorry, drive).

    Now, I've tried hunting around for the filter keys in the registry, added them and set to the values recommended on other posts on these forums and via MS's KB with no joy. I've also manually reinstalled all drivers involved, ensured there was no CD/DVD emulation packages installed or running and no burning software likewise. System restore, manual rebuilds, different optical drives -  and all with no joy.

    I'm guessing there's some nasty DRM stuff going on here, I'm not particularly into Windows software - mine "just works" and does so nicely, otherwise I'm a hardware monkey, and would appreciate some input Big Smile

  • Hi,


    For your reference, I knew a similar issue that occurred on a computer with Windows XP. Please click the following KB:

    You can no longer access the CD drive or the DVD drive, or you receive an error message after you remove a CD recording program or a DVD recording program in Windows XP: "error code 31"

    Besides, make sure the device is compatible with Windows Vista. You can find the Windows Vista Hardware Compatibility List here:


    I'm not sure how you add the filter keys, but as far as I know, there's a KB article that tell us how to delete the UpperFilters and LowerFilters key. Try to follow this KB:


    The CD drive or the DVD drive does not work as expected on a computer that you upgraded to Windows Vista

    Hope it helps.
