I was burned windows 7 on a 4 GB DVD-R with CD/DVD Burner. I think it was Nero CD/DVD burner.
Data (windows 7) was round about 733 MB in size. So, there should left round about 3GB free space on that DVD-R. But it is full. Properties showing that total capacity of DVD-R is 733 MB and 0 MB free out of 733 MB.
How can it be possible? I just write 733 MB on DVD-R.
Please help. Is there any way to recover that free space.
