Optiarc AD 7170a says all media is full<!-- google_ad_section_end -->
<HR style=“COLOR: #cccccc” SIZE=1><!-- google_ad_section_start -->so ive had this drive for about 6 months and everything has been fine with it. I went to burn a dvd the other day and it tells me to insert media with enough storage space. The problem here is that its a blank dvd+r. No Ive burned plenty of dvds and cds without any issues what so ever, not even media problems. I tried right after to burn a cd and the same thing happens. ive uninstalled the drive and restarted the comp and still no luck. Is the drive bad??? thanks in advance guys

Burning software is Nero


Is Alcohol installed?
