    Hello,
    I'm running XP on a 2 YO desktop. My two CD/DVD drives functioned perfectly until the other day. I've installed no new programs, but I think a Microsoft update happened at about this time.
    I tried the MS fix, deleting both upper and lower (i forgot the entire name) files in the registry. The I tried the MR FIXIT auto tool from Windows, no luck. I tried the solution I found on this forum here 525621-solved-dvd-cd-rom-drive.

    I see both drives in explorer, and trouble shooter in device mgr says they both are functioning. But, they both indicate that they are empty even though there is a disk in both. One disk is blank and the other I tried is a commercial dvd. No luck with either.

    TIA-
    Donna

    I have the same problem with my Sony DVD RW AW 170a. When I insert a normal DVD it read it perfectly but when I insert a DVD-R it doesn't detect it.

    I tried a CD in one of the two drives and now it says that it isn't functioning, and is inaccessable?

    Try this fix, make sure you follow it exactly

    Fix for missing DVD/CD drives.

    Create a text file with NOTEPAD containing the following data exactly as below and name it FIXCD.REG
    You should have 3 boxes on the bottom in NOTEPAD.
    1)Filename : fixcd.reg
    2)Save as type: all files
    3)Encoding: ANSI
    If you do not change it from txt type to All files type, then the file will actually be fixcd.reg.txt, this won't accomplish the desired result

    Double click on the file and say yes to the merge into registry question.

    ----------------------- Use text after this line, contents of FIXCD.REG -----------------------------
    REGEDIT4

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}]
    "UpperFilters"=-
    "LowerFilters"=-

    [-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdr4_2K]
    [-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdralw2k]
    [-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdudf]
    [-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UdfReadr]
    [-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdr4_xp]
    [-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdudf_XP]
    [-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UdfReadr_xp]
    ------------------------------ Use text before this line -----------------------------

    It didn't work. I loaded a DVD and it showed a message that Windows doesn't recognize it.

    The DVD I loaded was written using Track At Once meaning Multi session was enabled and my DVD is not reading any multisession dvds.

    Please help if you can

    You could try a system restore back to a time before the update or a repair of windows

    I would be better if you started your own post otherwise the responses start to get confusing

    I tried 2 different system restore points & that didn't work. Would uninstalling, disconnecting, and then reconnecting/installing them work?

    Thanks

    You could try uninstalling the drivers, reboot and see if windows sorts the problem.
    I had a similar problem with Win 7 the other day.
    I had just done a clean install and had everything running sweet when I noticed both the optical drives missing.
    I tried everything I know, hunted on the net nothing worked.
    I decided to do another clean install and now everything is OK,
    It niggles that I could not find the answer why
