Windows 7 Registry Fix to recognize the dvd drive.

• Windows 7 will not recognize the dvd drive

  Windows 7 will not recognize the dvd drive, although it worked well for more than two years.  Now I can't access it to install new software.

  It will not be displayed in the Device Manager, bad shooters to say it is not connected or is, tried Fixit fix (could not as "not applicable to your computer update"), uninstall iTunes (in the case of a conflict - even if it worked with the DVD of > 1 year), etc., but still cannot access the DVD.

  It's obviously a known issue, given that a support page - http://support.microsoft.com/kb/976187 that recommends the fix or manually disable ALPM active power management.  If it of a known issue, why is not included in the updates and that I have to disable ALPM power if management it worked ok before?

  What now? Is turn off the power, my only option?  What happens if it is not yet recognized after that?

  My computer windows 8 HP Pavillion M8100n does not recognize the DVD drive or the SD card reader.  I have just upgraded to Windows 8 of Window Vista. Do you have any suggestions?

  Hello

  I see nothing unusual, except that there should be a "0001", or even "0002"...

  When you have made the registry change, you used the command line (Admin)?... the process may not work with the regular command prompt...

• Windows does not recognize the DVD drive at startup

  Laptop: Dell E6410 ATG wt / verzion A15 Bios

  OS: Windows 7 SP1 with the latest updates.

  The question I have is when I log on Windows 7, the laptop does not recognize the DVD drive. The reader will not be displayed in my computer or Device Manager. I can get around this physically ejecting the disc and reinsert. If I do this drive appears in my computer Windows and Device Manager. It will read DVDs and CDs fine. I am able to reproduce the problem above mentioned question if I restart the laptop. If I restart the laptop the DVD drive won't be recognized and reinsert the drive will get it appears again.

  This problem occurs if I try a DVD - RW drive and an old DVD - ROM drive. If I go into the BIOS before windows, I can see the BIOS recognizing drives ok but not when initially get into Windows without having to eject and inserting the disc.

  Thanks in advance for any help.

  I guess that this must be a hardware problem then.

  Seems odd.

  The only other thing I can think of, after reinstalling W7, is a BIOS problem eventually. A strange setting it may be an older version of BIOS with a bug in it. If you decide to update the bios, make sure that you get the latest version for your make and model PC and follow the instructions. You can destroy a PC with bad BIOS or update the procedure.

• Windows Media Player does not recognize external DVD drive - so how do you watch a movie DVD?

  I just connected an external DVD - RW drive in my ultrabook of Windows 8 for the first time.  The ultrabook recognizes the drive and the dvd movie which are, but Windows Media Player only - only says: "connect a device".   The resolution of the issues said that the drive works properly.  I can't copy this movie at the video store, because it's a borrowed DVD.  So, how do WMP to recognize the DVD drive and play the movie?

  Hi HWH-CED,
  DVD playback is possible in 8 Pro windows media center. Player Windows Media 8 has no native codecs DVD added to it. You have the option to purchase an update for your Windows 8, which is Media Center Pack to allow playback of DVDs on your computer.

• Recognize the DVD drive in order to load Autocad

  I am running VMware Fusion on my iMac with Windows XP Home Edition. I have already loaded AutoCAD LT 2008 on my machine, and although it runs terribly slow it works.

  I'm now trying to load a version complete Autocad 2009 on the machine, but Windows does not recognize that I put the Autocad DVD in the DVD drive. He keeps asking for me to insert a disk.

  Since than the other version, on that I already loaded and Windows are literally the only things that I put on the side Windows of the machine I don't have much experience with this, but I don't see why it would not see the DVD drive.

  Any thoughts?

  I am trying to install a new drive CD-RW/DVD-RW on a Tecra M1; However, when the computer does not recognize the drive.

  Is there a solution to this?

  Thank you

  Colin

  For me it s case.
  I would say that the BIOS can't handle the new player properly because of the wrong master/slave/c-salt settings
  Readers slim for computers laptops support setting master/slave/c-salt settings and these settings can only be changed by changing the rider as on desktop drives.
  So it is very important that you purchase a compatible player and supported because disks with incorrect settings will not work.

  Before buying a car, you should ask the service provider to Toshiba for a caught player supported and compatible

• Why has my Windows 7 Home ceased to recognize the Fat32 drives?

  Until a few months ago, my Windows 7 Home had no problem reading disks formatted FAT32, including my HTC Incredible phone. But now he wants to just get myself in shape every time that I connect them via USB. The same readers are very well read by my laptop Windows 7 Starter and a Windows XP computer. I even tried connecting to a Windows 7 computer to work, and he wants to format the drive as well. I was installing a bad update or it will be a fix soon?

  Thank you.

  Hello

  Thank you for visiting Microsoft Community.

  From your description, I understand that Windows 7 does not recognize Fat32 drives.

  Please don't worry. I'll try my best to help you.

  Did you change your computer?

  Method 1: Run the troubleshooter to solve hardware problems or unknown device:

  Open the hardware and devices Troubleshooter

  How to use the System File Checker tool to fix the system files missing or corrupted on Windows Vista or Windows 7

  Method 4: Check which application is conflicted:

  Step 1: Start your computer in safe mode with networking

  http://Windows.Microsoft.com/en-us/Windows-Vista/start-your-computer-in-safe-mode

  If the problem does not occur in Mode safe mode with networking, we can use the approach 50 / 50 to narrow down the root cause of the problem.

  Step 2: Refer to the section below for instructions on how to start your computer in a clean boot state.

  do it right.

  Did you follow the Troubleshooting Guide for the reader who still does not work? There are
  the entries in registry that the troubleshooter does not solve and those who "might" be the cause.

  Check with your Maker system and a device for the two possible firmware updates and
  the correct registry entries for your car.

  Here are the keys that I of course are those in question - for the subkeys of the CD/DVD drive
  as there will be other subkeys in these keys. Do not forget to ask specific keys involved as well as
  the parameters.

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\IDE

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\0001\System\CurrentControlSet\Enum\IDE

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}

  You can probably find more info here and maybe even the exact registry for your CD/DVD settings
  drive from someone with the same model.

  Use DevManView to locate the CD/DVD in the registry (be careful and do a prior Restore Point)
  nothing change) - find the DevManView device and then make a right click on it free in RegEdit.

  DevManView - free - an alternative to the standard Windows Device Manager, which displays all the
  devices and their properties in flat table, instead of the tree viewer

  I hope this helps.
