Since XP doesn't natively write to DVD a new blank DVD+R or DVD-R (blank media) should show just as you wrote.
What software are you trying to use to record and support your new drive?
have a sony drx-830u external dvd recorder. when i go into my comp., it shows it as my f drive. when i try 2 open it, it says f is not accesable, incorrect funtion. when i hit properties + have a blank dvd in drive it says it,s full???? when i go into device manager it says it,s working properly. appreciate any help.
