I have two devices: HL-DT-ST CD-RW GCE-8483B and Sony DVD-ROM DDU 1615 things have always worked fine until last night I go to download some songs for my daughter to our Itunes account and the drives don't even turn on or spin or anything. I checked device manager and both have yellow exclamation points by them. When I check the properties for both, I get this message: "windows successfully loaded the device driver for this hardware but cannot find the hardware device (Code 41)." any suggestions? thanks.
