I had both my disc drives not work all of a sudden. I have a Dell desktop with Windows XP. When I try to read any type of data or music disc, I get a message: "Windows cannot read from this disk. The disk might be corrupted, or it could be using a format that is not compatible with Windows." I know the discs are not damaged because I can read them in my laptop.
This sounds like a driver issue, but I'm not sure if the Dell versions clobbered the working Windows drivers, or the other way around. Using Device Manager, expand and check the install dates on your various IDE/ATA/SATA, CD/DVD and USB drivers. See if anything coincides with when your drives started to malfunction. If you are able to read the drives after booting in safe mode, this would also point to drivers being the issue. If that is the case, use Control Panel/System Restore to restore the system files/drivers to a time before the disc issues appeared.
I removed McAfee and used the downloaded cleanup for McAfee. Microsoft Security Essentials was successfully downloaded into Vista, but I cannot turn on Windows Defender. I get an error message 0x800705b4. Is it necessary to have defender on? If so, how do I bypass the error message?
The stand-alone version of Windows Defender is incorporated into the Microsoft Security Essentials package. Why they don't automatically remove it upon installation, I don't know. Just go to Control Panel, Add/Remove programs and remove it.
