Matshita-DVD-ROM-UJ-850s-ATA-device doesn't read any CDs/DVDs
You mayy notice that your Matshita DVD- ATA device has stopped working properly and has stopped reading. This error is mostly due to the "Windows" operating system not being able to load the hardware device driver for this. The device driver may be corrupt or missing. Downloading a suitable device driver from Toshiba, if you don't have the CD-ROM from Toshiba. Bear in mind that this may lead to a crash in your software or damage to your hardware. Microsoft therefore doesn't encourage users to try and solve such problems by themselves by using various sites. It is best to refer to a professional/product manufacturer and use to official CD software.
