    Hello all. I wanted to add to your postings, and bay my own distain with a similiar suituation. We recently inherrited an IBM ThinkPad laptop computer. I re-installed windows, as the old system was horribly and errivisably corrupt. Upon doing so, and re-installing ( i used win ME) the DVD rom drive in the laptop suddenly decided to become a cd- rom drive. In the device manager, it appears under CD Rom Drives as what it is -- Mit****a DVD Rom SR 8175.
    However, under My Computer, it appears as Compact Disk Drive D. Sugestions? Questions? Comments??? I have un-installed this device, and re-installed it from the device manager... nothing is helping. DVD 's are not recognized, and CD's can play. The thinkpad we have is an A22 model.... Worse yet, Panasonic, the makers of this DVD Rom, have left it behind in their product line, so there is no more support for this drive available, including drivers.... Please..... help if you can! : (
    Thanks
    Jane

    Mits hi ta DVD Rom... why wont it let me write the name of the drive?? the previous should have appeared as all one word.. but it appears to have been censored.. hopefully this will work.

    this sounds like more of a driver/ software issue.

    I had a very similar problem with my dvd player. If I inserted a disk and tried to double click the drive in My Computer I would get an 'Incorrectt Function' error. Tried uninstalling the device and let the system find it again and still had the error. This is how I fixed it:
    1. Right click My Computer and click Manage.
    2. Click on Device Manager and right click the dvd drive and then click Properties.
    3. Go to the Driver tab and click Driver Details. You should see:
    C:\Windows\System32\Drivers\cdrom.sys
    C:\Windows\System32\Drivers\imapi.sys
    C:\Windows\System32\Drivers\redbook.sys
    C:\Windows\System32\storprop.dll

    If you see any other drivers listed follow the path to the folder (write down the name of the file without the .sys) and delete the file.
    4. Start > Run > regedit
    5. Search for the file name (eg if the driver file was named PxHelp20.sys search for PxHelp20) and delete any values found.
    6. Go back to Device Manager, right click the dvd drive and click Uninstall.
    7. Reboot and this should fix it.

    I have the same problem.
    My SONY VAIO laptop DVD RW DW-D56A drive can write sony's brand DVD+R disk without problem, but if I insert the disk and try to double click the drive in My Computer, it seems that the drive spins for a while and does nothing more. The same disk I can read Ok with my another desktop PC.
    To humberman :
    May you help me, I can not understand the step 5 of your post
    "..Search for the file name ...PxHelp20.sys ... and delete any values found."
    Actually, I found the name PxHelp20.sys in the Driver Details Properties.
    Do you mean only the key : HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PxHelp20
    or everything that I found in the registry?
    I did found a lot of keys and values with the word "PxHelp20" in the registry.
    Thanks in advance.

    Will this work if the drive reads dvd's as cd's? See http://www.techspot.com/vb/showthread.php?p=515143

    thanks geeksquad 851, your directions solved my problem, which was that the DW-56A DVD drive did't show up in the windows explorer. (Error Code 19, corrupt registry info)

    i uninstalled alcohol 120 and winoncd (the problem occured roughly around the time of winoncd's installation (on a custom xp version)), deleted the upper and lower filters in the registry and rebooted; the drive showed up again.

    thanks so much for saving me a reinstallation.
