I have a 6-month old computer running Vista with a CD/DVD drive which I have used to read and write. But as of a couple weeks ago it is unusable because it is not recognized by the OS. In Explorer or My Computer, the E:\ drive does not even appear in the list. In Control Panel when looking at the CD/DVD drive information it states that there has been corruption in the registry. I have no idea what I might have done to cause that. When I try to re-install the driver from the internet, it first checks and tells me that I have the most recent version of the drive so no need to re-install. Should I uninstall the driver and then re-install?
