I have being trying to burn a 90min CD on my NEC 4551, but the drive only sees it as 702Mb when it should be 800Mb. I got round it by using the overburn feature of Nero (which i don’t like doing). Then out of interest i put a blank CD in my old BTC DVD writer, went to my computer and the disk showed up as having 799Mb free space. Can anyone tell me why my NEC cannot see this extra space? Once burnt the NEC drive can see that there are 773Mb on the disk but seems unable to detect an 800Mb blank disk.
It might be the media. Try a different brand of CDRs.
