Re: Is this normal.
It's possible that you may need to reinstall your CD drive's drivers. Right click on My Computer (or Computer for Vista) and go to Manage, then select Device Manager and look at where the CD/DVD drives should be. If it is listed with a yellow exclamation mark next to it, you need to install the drivers. If it isn't listed, open up your case and make sure that the IDE or SATA cable is plugged in. If not, plug it in and then see if that makes a difference.
