Hope this is a software issue, but fear it may be hardware.
Acer Aspire 5750 laptop, Windows 7 Home Premium, 64 bit. Pioneer DVR-TD11RS DVD/CD drive.
While burning music to a CD using WMP, I encountered a failure. Now the drive will not recognize that a CD is in the drive. Will not see either a blank CD disk or a commercial CD disk. However, it does properly play a DVD.
Device manager tells me the device is working properly. I uninstalled/reinstalled the driver from device manager. Microsoft Fix-it doesn't fix it. A quick look in the registry does not show any upper or lower filters. 'Opti Drive Control 1.70' does not see a disk so will not allow me to do any tests.
Does not see a disk in safe mode. Tried booting from the CD drive with a bootable disk - no luck. Found an exact replacement drive on ebay and tried that. Same results. I have a slimSATA to USB adapter cable on order, and will try the drive(s) externally when arrives.
I'm down to suspecting a motherboard failure in the data path, but am crossing my finger that it may still be a software issue. Any suggestions? Thanks.
