    I have an IBM Lenovo 7732a13 with a Matshita uj 850 where the DVD doesn't work. Device manager is reporting that it can't load the device driver Code 39.

    That driver is definitely loaded. What next?

NOTE: If prompted for an administrator password or a User Account Control prompt is displayed, type the appropriate password or click Continue.

This is a problem with several answers, however; for the most part, consider the Media that is inserted into the drive. If it is a COPY for example, the copy made on another computer may not line up correctly. The CD/DVD has magnetic lines that are true, very much like a phonograph record. If they do not line up correctly, they will not Read or Write. The other problem can be the Laser Head. If the reading head is misaligned, it too will have a problem reading data. The best way to get around the problem is to transfer the data from the CD/DVD media to a USB Flash drive, and go that route, or get an external USB CD/DVD for about 30 bucks at Wal Mart.

Matshita dvd-ram uj-850s ata device cannot start (code 10).my laptop is toshiba A100,vista home premium . i cannot use my dvd ,please i need to solve this problem without losing my files ibrahim

After i try to find the registry (which is not available)
Why not give this a try:
  1. Start your computer after SHUTDOWN
  2. After your DESKTOP appear on the screen for about 10 second, QUICKLY INSERT ANY CD/DVD (in my case I insert Glee)
  3. Let the computer run for a while, don't do anything until it settle down
  4. Check at MY COMPUTER whether your cd is detected
  5. I got mine work this way!. Good Luck my friends!
