Unable to read media in DVD-RW/CD-RW drive

I have a laptop computer with Windows Vista Ultimate 32-bit version installed.
I have two desktop computers with Windows Vista Ultimate installed, one with the 32-bit version installed and one with the 64-bit version installed.
All three computers have an annoying quirk with reading media in the internal DVD-RW/CD-RW drives installed in the computers.
If there is no media in the DVD-RW/CD-RW drive when a computer is booted up, when a DVD or CD disc is inserted into the drive the files on the DVD or CD disc cannot be read.
Trying to open the DVD or CD disc with Windows explorer results in a message that the disc is blank and asking if the disc should be formatted.
This problem occurs whether the media inserted is from retail software packages or is recordable media to which files have been written.
I can use InfraRecorder or PowerISO DVD/CD burning software to successfully burn files to DVD-R/CD-R blank media while this is happening, but the burned media cannot be read by Windows explorer on that computer after burning either.
I have tried all of the options in the Windows AutoPlay function with identical results.
If there is a DVD or CD disc in the DVD-RW/CD-RW drive when the computer is booted up, Windows explorer can read files on that disc or any disc that is subsequently inserted into the DVD-RW/CD-RW drive.
This is true whether the media inserted is from retail software packages or is recordable media to which files have been written.
When the 'Computer' icon is opened with Windows explorer, the title of the disc stays the same as the disc that was in the DVD-RW/CD-RW drive when the computer was booted up regardless of subsequent discs that are inserted into the DVD-RW/CD-RW drive.
I do not care if Windows explorer updates the title of the DVD or CD disc as long as the contents can be read, so I have put up with my work-around of always leaving a disc in the DVD-RW/CD-RW drive when the computer is booted up.
I never experienced the referenced problem in years past when using Windows XP on the three referenced computers or any other computer.
Is there some method to fix this problem with Windows Vista, so that I will not have to ensure that media is inserted into the DVD-RW/CD-RW drive when the computer is booted up if I want to use the DVD-RW/CD-RW drive to read files from any media inserted inserted into the drive?
