    Laptop no longer detects DVD drive, usual fix unsuccessful

    Hi all,

    I bought a Packard Bell laptop in March which runs off Vista. Yesterday I
    tried to run a game I had been playing for weeks by clicking the normal icon.
    I received an error message stating "We cannot detect a CD-Rom drive on your
    system". I tried the same with a variety of other DVDs and received the same
    message each time. The DVD drive in question has worked fine up 'til now and
    still seems mechanically sound (i.e. it accepts DVDs/open/closes) but it now
    also doesn't autorun a DVD on insertion.

    I have looked at Device Manager and it now doesn't show a CD or DVD drive at
    all. Under Disk Drives it does show a ST912082 2AS SCSI Disk Device with a
    message that this is working properly, but I assume this is the hard drive.

    I searched the web and found a fix that involves disabling the upper and
    lower filters of the relevant class in HKEY_Local_Machine. I did that but
    nothing seems to have changed following the restart - the computer still
    doesn't recognise that a DVD drive even exists. It looks like this problem
    normally occurs when you upgrade or switch to Vista. In my case, the DVD
    drive has been recognised for months by Vista, but now, suddenly, it is not.
    I can't think of anything I've installed or uninstalled in the last few days
    which may have led to this.

    I'm currently backpacking in some quite remote places so support is
    difficult to find, so any suggestions very gratefully received! Sorry for
    such a long post, but hope it's thorough.

    Kind regards
    Sean

    Thanks for the excellent post. Very good details. See if the drive is
    detected in the BIOS. When you first start the computer there will be a
    line that shows you what key to press to enter Setup (the BIOS). If the
    drive is not seen there, it is a hardware problem. With some laptops you
    can remove the optical drive and put it back in again. Sometimes this
    fixes whatever wasn't physically making contact. If not, the drive or
    the motherboard controller for the drive may have died and I don't see
    what you can do about it in the Back Of Beyond. If the drive *is* seen
    in the BIOS, the normal way I like to check in these cases is by booting
    a rescue system on a CD like Knoppix or a Bart's PE. Unless you've got
    one of these in your backpack, this is going to be pretty hard to do
    where you are.
